I recently received an email about carbohydrate content in CET chews. I contacted the manufacturer to confirm that there are indeed very little carbohydrates in these dental chews, but I thought this would be a good time to discuss carbohydrates for diabetic pets.

Kitties are true carnivores and do very well on low carbohydrate diets. The insulins we tend to use on cats (glaurgine, PZI) are long lasting. Cats tend to nibble on their food throughout the day, and diabetic cats have fewer glucose spikes when fed low carbohydrate foods. Low carb diets are the diet of choice for most diabetic cats.

Dogs, on the other hand, are omnivores. Of course we don’t want to give a dog a Snickers bar, but carbohydrates are not the enemy. Quality complex carbs are important for a diabetic dog’s diet. The insulins we typically choose for dogs are intermediate acting as dogs tend to meal feed rather than nibble throughout the day. If you wish to give your dog a special treat (such as a CET chew), you might choose to give it just before or just after the meal. Perhaps decrease the amount fed at that meal to keep consistency with your pet’s diabetic routine. Treats given in between insulin doses might cause an unwanted spike in the pet’s blood glucose.

I was recently chatting with a friend who had just joined Weight Watchers. She is a highly functional and intelligent woman, yet she didn’t understand the difference between “good carbs” and “bad carbs”. Put simply, the more refined a carbohydrate is, the faster it will cause the blood glucose to rise. For example, white bread will cause a glucose spike more quickly than whole grain bread. A sugary snack will cause the blood glucose to rise rapidly. Broccoli and other green veggies would have very little impact on the blood glucose. For diabetic dogs, we try to avoid highly refined and sugary carbohydrates and opt instead for complex carbohydrates. If you feel compelled to give your diabetic dog a simple carb, at least give it around meal time to avoid a mid-day glucose spike.

Perhaps this is a good time to remind ourselves about our own eating habits. Dogs typically want whatever we (their humans) are eating. I highly doubt they get cravings for donuts or cheese burgers. If we don’t keep “junk food” in the house we are less likely to eat it, and we are therefore less likely to give any to our pets with their soft brown pleading eyes. If we eat sugary snacks and pastries, our taste buds don’t appreciate the natural sweetness in apple slices or baby carrots. It’s just a thought.

NOTE: Consult your veterinarian to confirm that my recommendations are applicable for the health needs of your pet.
