Roundworms!!



Canine and feline Roundworm!!

What is it and how does your pet get it?


Roundworms are a type of intestinal parasite commonly found in the digestive tracts of cats and dogs. This parasite can be passed from Dam to babies during nursing, across the placenta when puppies are in utero or through the ingestion of contaminated hosts or soil. Soil that has embryonated (infective) eggs or hosts that have ingested embryonated eggs pass roundworm infections on to dogs and cats when consumed. Eggs become embryonated after they have been exposed to the elements. Once the embyonated eggs are ingested they hatch out and migrate thoughout the body. The adult roundworms can be found in the small intestines.

Why have fecal examinations on your pet?

Fecal examinations are a great way to detect many intestinal parasites in your pet. Roundworms are only one of hundreds of intestinal parasites found in cats and dogs. Fecal examinations look for the microscopic eggs that are shed by mature adults. You will not always see stool changes if there is an active infection. It depends on the type of parasite, stage in the lifecycle of the parasite and number of parasites present and your pets’ sensitivity to the infection.

Why deworm puppies and kittens?

It is known that puppies and kittens can become infected in utero and puppies can become infected while nursing. If infection is present, it can affect growth and development of the puppies and kittens. Poor hair coat, pot-bellied appearance, and in severe cases death may occur. Puppies and kittens can shed eggs in the environment and then can infect other animals. When puppies and kittens are dewormed then the lifecycle can be broken.
Not only can roundworm infections affect your pet, but it is also a zoonotic disease. A zoonotic disease is something that can be transmitted between humans and animals. Dog and cat Roundworms can cause health concerns in people, particularly in children. Children tend to play in dirt that can harbour roundworm eggs and they tend to be less hygienic than adults. Health concerns in people from dog or cat roundworm can be caused by larva migrating through tissues in the body.  The parasite can travel through tissues causing inflammation. Many people may be asymptomatic for infection.

How do we prevent infection?


Regular veterinary care for your dog and cat, including fecal examinations, strategic deworming and monthly preventatives can help protect your pet. Stooping and scooping is a good practice to minimize transmission of many parasites. Eggs can be long lived in the environment. Hand washing is very important. After handling pets, playing outside and before preparing or eating food washing hands can decrease transmission to people. Do not allow your child to eat dirt or play in areas soiled by animals. Covering children’s sandboxes when not in use can also help prevent infection. Pets are a great pleasure for people and the risk of transmitting parasites to humans can be very small if the recommendations are followed.

Spring Time Toxins

Tips from Pet Poison Helpline to Help Keep Your Pet Safe!
By Erica Carghill, CVT and Justine Lee, DVM, DACVECC

Spring is just around the corner!  Plant bulbs are just as excited to break through the ground to add some color to our yards, as we are to see some greenery!  That said, we need to be aware of the potential dangers spring plants can be for our pets.  Here is a list of some of the most common spring plants and their toxicities… so you know how to pet-proof your garden and keep your pet safe!
Tulips and Hyacinth
Tulips contain allergenic lactones while hyacinths contain similar alkaloids.  The toxic principle of these plants is very concentrated in the bulbs (versus the leaf or flower), so make sure your dog is not digging up the bulbs in the garden.  When the plant parts or bulbs are chewed or ingested, it can result in tissue irritation to the mouth and esophagus.  Typical signs include profuse drooling, vomiting, or even diarrhea, depending on the amount consumed.  There is no specific antidote, but with supportive care from the veterinarian (including rinsing the mouth, anti-vomiting medication, and possibly subcutaneous fluids), animals do quite well.  With large ingestion of the bulb, more severe symptoms such as an increase in heart rate and changes in respiration can be seen, and should be treated by a veterinarian.  These more sever signs are seen in cattle or our overzealous, chowhound Labradors.
Daffodils
These flowers contain lycorine, an alkaloid with strong emetic properties (something that triggers vomiting).  Ingestion of the bulb, plant or flower can cause severe vomiting, diarrhea, abdominal pain, and even possible cardiac arrhythmias or respiratory depression.  Crystals are found in the outer layer of the bulbs, similar to hyacinths, which cause severe tissue irritation and secondary drooling.  Daffodil ingestion can result in more severe symptoms so if an exposure is witnessed or symptoms are seen, we recommend seeking veterinary care for further supportive care.
Lilies
There are dangerous and benign lilies out there, and it is important to know the difference.  Peace, Peruvian, and Calla lilies contain oxalate crystals that cause minor signs, such as tissue irritation to the mouth, tongue, pharynx, and esophagus – these result in minor drooling.  The more dangerous, potentially fatal lilies are true lilies, and these include Tiger, Day, Asiatic, Easter and Japanese Show lilies – all of which are highly toxic to cats!  Even small ingestion (such as the pollen or 2-3 petals or leaves) can result in severe kidney failure.  If your cat is seen consuming any part of the lily, bring your cat (and the plant) immediately to a veterinarian for medical care.  The sooner you bring in your cat, the better and more effectively we can treat the poisoning.  Decontamination (like inducing vomiting and giving binders like activated charcoal) are imperative in the early toxic stage, while aggressive intravenous fluid therapy, kidney monitoring tests, and supportive care can greatly improve the prognosis.
Crocus
There are two Crocus plants:  one that blooms in the spring (Crocus species) and the other in the autumn (Colchicum autumnale).  The spring plants are more common and are part of the Iridaceae family.  These ingestion can cause general gastrointestinal upset including vomiting and diarrhea.  These should not be mistaken for Autumn Crocus, part of the Liliacease family, which contain colchicine.  The Autumn Crocus, also known as Meadow Saffron, is highly toxic and can cause severe vomiting, gastrointestinal bleeding, liver and kidney damage, and respiratory failure.  If you are not sure what plant it is, bring your pet to their veterinarian immediately for care.  Signs may be seen immediately but can be delayed for days.
Lily of the Valley
The Convallaria majalis plant contains cardiac glycosides, which will cause symptoms similar to digitalis (foxglove) ingestion.  These symptoms include vomiting, diarrhea, a drop in heart rate, severe cardiac arrhythmias, and possibly seizures.  Pets with any known exposure to this plant should be examined and evaluated by a veterinarian and treated symptomatically.
In addition…. Fertilizers
As we gardeners work on our rose garden, be aware of those fertilizers.  While most are not very toxic (resulting in minor gastrointestinal irritation when consumed), some fertilizers can be fatal without treatment.  Here are a few ingredients to be aware of so you know what toxins and symptoms to watch out for:
·         Blood meal – This is a dried, ground, and flash-frozen blood and contains 12% nitrogen.  While it’s a great organic fertilizer, if ingested, it can cause vomiting and diarrhea.  More importantly, it can result in sever pancreatitis, which is inflammation of the pancreas.  Some types of blood meal are also fortified with iron, resulting in iron toxicity, so make sure to know what is in your bag of blood!
·         Bone meal – This is made up of defatted, dried, and flash-frozen animal bones that are ground to a powder.  This “bone” is also what makes it so palatable to your dog so make sure to keep your pet from digging in it and ingesting the soil.  While this also makes a great organic fertilizer, it can become a problem when consumed in large amounts as the bone meal forms a large cement-like bowling ball foreign body in the stomach – which can cause an obstruction in the gastrointestinal tract – resulting in possible surgery to remove it!
·         Rose and plant fertilizers – Some of these fertilizers contain disulfoton or other types of organophospates (OP).  As little as one teaspoon of 1% disulfoton can kill a 55 lb dog, so be careful!  Organophosphates, while less commonly used, can result in severe symptoms [including SLUD signs (which abbreviate for salivation, lacrimation, urination and defecation), seizures, difficulty breathing, hyperthermia, etc.  In some cases, it can be fatal!
·         Pesticides / Insecticides  - Most pesticides or insecticides (typically those that come in a spray can) are basic irritants to the pet and are usually not a huge concern unless a pet’s symptoms become persistent.  Some may contain an organophosphate which can be life threatening when consumed in large quantities.  It is always best to speak to a trained medical professional if there are any questions.
·         Iron – This is commonly added to fertilizers, and can result in iron toxicity (from ingestion of elemental iron).  This is different from “total” iron ingestion, and can be confusing to differentiate.  When in doubt, have a medical professional at Pet Poison Helpline assist you with finding out if the amount ingested was toxic or not.  Large ingestion can result in vomiting, bloody diarrhea, and potential cardiac and liver effects.

The best thing any pet owner can do is to be educated on the household toxins (both inside the house and out in the garden!), that way you make sure how to pet-proof your house appropriately.  Make sure to keep all gardening and lawn products in labeled, tightly sealed containers out of your pet’s reach.  If you think your pet has been poisoned, contact your veterinarian or Pet Poison Helpline at 800-213-6680 with any questions or concerns.

 Resources:  Pet Poison Helpline (PPH) is an Animal Poison Control that provides treatment advice and recommendations relating to exposures to potential dangerous plants, products, medications, and substances, to veterinarians, veterinary staff and pet owners 24 hours a day, 7 days a week.  Please be aware there is a $35.00/per case consultation fee.  Pet Poison Helpline is located in Minneapolis, Minnesota.  The Helpline number is 800-213-6680.

Weighty Issues: Body Condition Scoring

So, now that we have discussed that obesity is a disease that is preventable and manageable, it’s time to figure out where each of our pets fall in the spectrum of obesity. To do that, we need a few different pieces of information: a weight, and a body condition score.

The first thing most people do when bringing their dog to the clinic is to pop them on the clinic scale. When cats come out of the carrier, the first place they land is on the cat scale. This is a vital piece of information for the veterinary clinic, as it allows us to accurately dose your pet should he or she need any medication, and we can also track the weight over progressive visits to monitor weight gain or weight loss.

But veterinarians and technicians are also assessing a body condition score. When we give your pet a good rub down in the room, we aren’t just being friendly. We are feeling fat padding, muscle tone and the prominence of bones like ribs and hips. Based on this tactile assessment and also a visual look at the waist and belly, we assign your pet a body condition score. Body condition scores can be out of 9 or 5, and this allows us to translate whether that 10kg dog is healthy, overweight or underweight.

You can do body condition scoring at home. It takes a bit of practice, and keep in mind that body condition scores are subjective analysis of your pet. Don’t be surprised if you and your vet disagree slightly in the scoring – we all tend to be a bit more optimistic regarding the health and weight of our own pets, where as your vet likely has a more critical eye. Personal experience can also affect how we view weight issues – what we perceive as normal will be very different depending if we spend all day at the dog park watching pudgy labs play,  versus spending time at a sport-dog competition where pets are typically more trim.  

To perform a body condition assessment, start with feeling your pet over its chest area, using light palpation. You are gauging how prominent the ribs are. Ideally, you should not have to dig too deeply to be able to feel your pet’s ribs.


Next, move your palpation down to your pet’s abdomen. You are feeling for the presence of a waistline and also a “tummy-tuck”. Now run your hands down your pet’s spine, hips and tail, feeling for excess fat accumulation. Cats in particular are prone to developing a fat pad in front of their hind legs. If your previously-overweight cat has been on a weight-loss program and is doing well, don’t be surprised if this fat pad remains longer than you’d like. It’s often the last evidence of obesity to disappear.

Compare what you feel and see to the scoring charts – there are different ones for toy, small, medium, large and giant breed dogs and also cats: http://www.pet-slimmers.com/pet-obesity/how-to-tell-if-your-pet-is-overweight.aspx

If you’ve done this scoring and feel your pet is anything other than ideal (4-5/9), call your veterinarian today to discuss what you can do to get your pet in its optimal body condition.

Weighty Issues: Pet Obesity

Obesity is one of the most common diseases that is identified in our companion animals. Yes, I said disease. Obesity is a disease that can greatly affect a dog’s or cat’s overall health and life-span. It is more than a cosmetic issue; it is a health-risk. The good news? Obesity is manageable, but not only that, it is preventable.

A dog or cat is classified as overweight when they weigh more than 10% of their ideal body weight; they are obese when they weigh more than 20%. Animals can be predisposed to obesity from a variety of factors, including genetics, neutering and endocrine disorders, but the most common cause of obesity is energy imbalance. Put simply, animals are often fed too much and exercised too little.

Cats and dogs that are obese have reduced quality of life and their life-expectancies can be greatly shortened. Furthermore, obese pets are at higher risk for many disorders, including:
  • Cardiac disease
  • Respiratory disease
  • Osteo-articular disease
  • Urolithiasis (urinary stones)
  • Diabetes mellitus
But obesity is a touchy subject. In a world where the statistics involving human obesity is on the rise, many people are inclined to take any discussion regarding overweight or obese animals personally. The fact is, most vets are not being judgemental or mean when they diagnose a pet as obese or overweight; they have the pet’s best interests at heart. It is a medical fact, the same as diagnosing an animal with a fractured tooth or a broken leg or a heart condition. Similarly to those conditions, treating an animal’s obesity can greatly increase their life-span and make them more comfortable.

The problem with obesity is that it is not a curable condition. It is a chronic concern that will affect that pet’s entire life. An overweight animal can’t just start a diet, loose a few pounds and then go back to eating lots and exercising less. Obesity will recur, and many weight-loss programs must be maintained for life to keep an animal in ideal body condition.

In animals that are obese, simply cutting back on the current diet is not enough. Maintenance or even weight-control diets are not properly formulated for weight-loss. Severe restrictions of these diets can result in vitamin and mineral deficiencies, not to mention hungry pets. To achieve healthy weight loss, animals need correctly-formulated calorie-controlled diets that make an animal feel full so there is less begging or food-stealing, which can be a hiccup in most weight-loss plans. Proper exercise is also very important and needs to go hand-in-hand with proper nutrition.

This may sound very complicated. Not to worry – this is why your veterinarian is here. We have access to all the latest research in nutrition, plus special diets that have been put through rigorous testing and formulating – and that we have seen WORK to achieve weight loss. We would love to help, and celebrate the victories with you!

Pet Food Nutrition: the Truth About Corn

 
There has been an increasing trend in the movement of pet food companies to exclude ingredients like corn based on the perception that it is an undesirable ingredient. It has been described as an indigestible "filler" ingredient (ingredients that do not contribute to any nutritional or beneficial properties to a food) that leads to food allergies. The reality is that most concerns regarding corn are invalid.

Remember: true food allergies are uncommon in dogs and cats. It has been estimated that only 1% of all skin diseases can be attributed food allergies; more often flea-allergy dermatitis and atophy are responsible. Most gastro-intestinal conditions that respond well to diet changes are actually more food-sensitivities or intolerances to properties of the diet such as fat or fibre content.

Further more, corn is a rare cause of food allergies. More often, allergies occur to other ingredients including beef, dairy and chicken. In general, animal-based protein is more commonly a cause of allergies rather than plant-based ingredients.

So while there is little evidence to support the exclusion of corn, corn is also a source of essential nutrients. It contributes fibre, protein, vitamins, minerals and high-digestible carbohydrate to a diet. It is also one of the riches sources of linoleic acid, an essential fatty acid, and as such is not a "filler" ingredient.

When it is properly processed (ie: rolled, ground, flaked, cooked), corn's digestibility greatly increases. Whole ground corn cooked via extrusion (the way that most dry pet food is made) has been shown to have a digestibility of greater than 97% in dogs and cats!

Corn, like many other ingredients, has managed to develop a bad reputation based little on fact and more on myth. As always it is important to educate yourself on interpreting pet-food ingredients and marketing strategies, differentiating real information from hype. As always, your veterinarian can help you sort out fact from fiction when choosing an ideal diet for your pet.

Brushing your Dog or Cat's Teeth

How often do you brush your cat or dog's teeth? Do you know the optimal amount of brushing that is recommended to help control the progression of dental disease?

Just like humans, cats and dogs require daily brushing of their teeth to provide the best control over the progression of dental disease. Many things can contribute to dental disease, including diet, age, breed and genetic predisposition. But the more at-home dental care you can provide, the better off your pet's teeth will be.

Starting a teeth-brushing regime can seem like a daunting task if you've never brushed an animal's teeth before. Here are some easy tips to help you get started.

1) Start with getting your dog or cat used to having its mouth handled. Rub the muzzle, massage the gums, and be sure to make sure everything ends on a positive note.

2) Introduce a small amount of toothpaste with your finger. Rub this against the teeth and the gums to get your pet used to the taste and sensation. Be sure to use a toothpaste designed for dogs and cats.

3) Bring on the toothbrush! Wet the bristles down and start brushing the larger canine teeth in gentle circular motions.

4) Work your way back across the rest of the teeth, increasing the time and pressure used on each tooth. Focus on the outside surface of the teeth; tartar rarely occurs on the inner surfaces

5) Finish with brushing the front teeth by holding the muzzle with your other hand and lifting the lips to allow access.

When you are first introducing this to your cat or dog, you may need to start very slowly, and reward after each step. Do not rush into a full brushing as your dog or cat may object and be more resistant next time. The end goals are an easy teeth-brushing experience every time, fresher breath and a healthier pet!

Pet Food Nutrition: Grain-Free Diets

Dogs and cats are both classified in the order Carnivora. Does that mean that they should receive a strict meat-only diet? Are certain carbohydrate-sources better or worse than others? Do grain-free diets provide health benefits over those that contain grains?

Contrary to popular belief, grain-free diets do not offer health benefits over diets than contain grains. Dogs are actually considered omnivores (and thus more similar to bears, skunks and racoons), and both dogs and cats have the ability to digest, utilize and benefit from a nutritionally balanced diet containing carbohydrates, including grains. In fact, animals do not treat grains differently from other sources of carbohydrates like potato and apple – the body recognizes the food by the nutrients it provides, not by its source. The starch (the main carbohydrate) in grains is actually highly digestible for both dogs and cats – 95% or higher.
Many manufacturers, in an attempt to make their diet stand out in a competitive market, advertise grain-free diets as being healthier, when in reality they are readily comparable to their grain-containing counterparts. Many grain-free diets are not actually lower in carbohydrates, but rather use alternative sources of carbohydrates, such as potatoes and tapioca, which are actually lower in protein and higher in sugars than grains.
So what other benefits do grain-free diets claim? Some claim that the risk of food allergies, obesity or diabetes is higher in diets that contain grains as the source of carbohydrates. True food allergies (reaction of the immune system to certain food proteins) are actually quite rare but can be caused by any ingredient that has protein. Food intolerances (which don’t involve the immune system) are usually in response to certain nutrient profiles, such as high-fat diets, and are rarely related to grains specifically. The most common allergies in dogs are beef, dairy, wheat, chicken and egg; in cats beef, dairy and fish are most common. Usually animal proteins are more common causes of allergies than grains or other carbohydrate sources. However, if an animal is truly allergic to a single type of grain (for example, wheat), feeding other types of grains (like oats and rice) should not be a problem.
Obesity is a serious disease that affects a large number of our animal friends. However, the main cause in both dogs and cats is excessive calories – regardless of the source. Many grain-free diets are actually higher in calories and fat; they can be easy to over-feed and the fat makes them very palatable. Regardless of the type of diet fed, owners should monitor their pet’s body condition and weight carefully and feed accordingly.
Diabetes in dogs is related to the destruction of specific cells in the pancreas, and cannot be induced with diet. However, it has been shown that achieving and maintaining optimal weight and providing a consistent diet and meal times can help in managing the disease in dogs. Cats, on the other hand, are prone to developing diabetes if their weight is not-well managed. As mentioned above, diets containing grains do not promote obesity. While some research has shown that diets with lower carbohydrate content can be useful in managing diabetes in cats, most of these diets contain grains.
While grain-free diets can provide excellent nutrition, they do not offer health benefits over diets than contain grains. It is important to assess your pet’s diet based on overall nutrient profile rather than individual ingredients, and to not be swayed by marketing tactics.
