Killing Our Dogs With Kindness

He may be your best friend, but you run the risk of becoming his worst enemy. When it comes to your dog, beware the familiar adage about killing with kindness—for too many of us the temptation to make our canine pals happy extends to feeding them foods that we enjoy but that may prove deadly for them.

“The most common is chocolate poisoning but I've also seen onion, marijuana, and acetaminophen (Tylenol). The latter is a cat problem. Except for onions, these are acute poisonings,” reports Dr. Jeff Grognet, a veterinarian, dog writer and online instructor with a practice in Qualicum Beach, British Columbia, Canada. Except for a finicky handful, dogs tend to be indiscriminate consumers and highly motivated beggars, obsessed with human food—they have a gourmand’s appetite, equating quality with quantity.

So while your pet may get away with occasionally gulping down an errant tiny piece of chocolate for example—a healthy chunk containing the problematic ingredient, theobromine—could cost your dog its life. Dark cooking chocolate is particularly dangerous and contains high theobromine content.

The size and weight of your dog are important factors to consider.

“I don't think breed is an issue but size certainly is—it’s easier to poison a small dog than a big one,” says Dr. Grognet.

If your dog suddenly and without warning begins to vomit or salivate excessively, if he appears lethargic or depressed, begins to convulse or hemorrhage—consider the possibility of poisoning.

“…Any sign that causes concern—vomiting (intestinal blockage, chocolate), convulsions (chocolate), red urine (onions), delirium (chocolate), lethargy (grapes), drinking excessively (grapes), vomiting blood (painkillers),” advises Dr. Grognet.

Even some foods designed for canine consumption warrant monitoring according to Dr. Grognet.

“I'm not a fan of rawhide because it can get stuck and cause blockage, requiring surgery. The same can be said for any treat if a large piece is swallowed. Some imported rawhides have been found to contain toxic ingredients. There have been cases of certain treats being recalled due to bacterial problems but this is rare.”

Common Canine Food Perils:
  • Avocado
  • Chocolate
  • Grapes and raisins
  • Coffee
  • Onions, onion powder
  • Garlic
  • Yeast Dough
  • Salt
  • Products featuring xylitol—sugarless candies
  • Moldy, spoiled or fatty foods
  • Alcohol
  • Macadamia Nuts
  • Turkey skin (can cause acute pancreatitis)
  • Raw salmon
  • Broccoli (in large amounts)
  • Mushrooms

Human medications such as pain killers, (especially: ibuprofen and paracetamol), cold medicines, vitamins and many prescription drugs can also be lethal to your pet, as can common household cleaners, including automatic toilet bowl cleaners.

Outdoor hazards include cocoa mulch, citronella candles, insect baits, antifreeze, mothballs, post-1983 pennies, batteries, potpourri oils, and fabric softener sheets.

Ethylene glycol (EG), a toxic component of antifreeze is a common lethal form of poisoning. In British Columbia alone there were more than 1,000 cat and dog deaths as a result of EG toxicity in one year, reports Dr. Grognet. In order to be successful, treatment must begin within an hour of ingestion.

As an alternative to antifreeze, Dr. Grognet suggests using propylene glycol, which, though more costly, is less toxic and less tasty than EG.
