Practice Scenario
Meet JAX
A 12-week-old, male, purebred Jack Russell Terrier puppy
- Jax is presented at the clinic for physical examination and additional puppyhood vaccinations.
- Jax is the first puppy — and first dog — for this owner, who would like recommendations on feeding and caring for him.
- The owner is currently feeding a dry puppy food mixed with warm water, as recommended by the breeder who sold the puppy.
Feeding Management
Toxic Foods for Dogs and Cats
A basic principle of toxicology says “the dose makes the poison.” This adage applies to many common food items, which may contain natural chemicals that can be toxic when consumed in sufficient quantities. The potentially harmful amount may differ among species, so what may be safe for people to eat may be dangerous for pets. When some dogs — and an occasional cat — get access to certain foods (e.g., chocolate candy, baked goods, moldy foods in the garbage), they might eat an amount that provides a dangerous dose of the potentially toxic substance or overwhelms their bodies’ ability to process it.
Key Messages
- Some foods, while safe for people to eat, may cause a wide range of health issues for dogs and cats. While veterinary toxicologists know why some foods cause poisoning in pets (e.g., theobromine and caffeine in chocolate), they have yet to identify the toxic agent in others (e.g., grapes, raisins and macadamia nuts).
- Dogs are far more likely to experience food-related toxicities than cats due to their scavenging nature and tendency to investigate the environment with their mouths.
- The list below is not exhaustive; however, it includes those foods most commonly reported to animal poison control centers.
| Food | Potential Health Problems |
|---|---|
| Chocolate | Vomiting, diarrhea, increased heart rate, high blood pressure, abnormal heart rhythm, tremors, seizures |
|
Xylitol (natural sweetener found in certain sugar-free gums, candies, baked goods, toothpastes) |
Low blood sugar (glucose), liver failure |
| Coffee, tea and other caffeinated drinks | Hyperactivity, restlessness, vomiting, fast heart rate, rapid breathing, tremors, abnormal heart rhythm |
| Raw or cooked onions, garlic, leeks, chives (Allium spp.)* | Lower-than-normal number of red blood cells due to cell damage and breakdown, digestive upset, increased heart rate, increased breathing rate |
| Grapes, raisins, Zante currants (Vitis spp.) | Digestive upset, loss of appetite for food, sudden kidney failure |
| Macadamia nuts | Hind limb weakness, vomiting, poor balance or coordination, tremors, increased body temperature, joint stiffness |
| Alcohol (ethanol) | Depression or lethargy, incoordination, vomiting, decreased breathing rate, low blood sugar, low blood pressure, low body temperature |
| Raw yeast-containing dough | Lethargy, incoordination, vomiting, decreased breathing rate, low blood sugar, low blood pressure, low body temperature, bloating with possible stomach twisting, seizures, respiratory failure |
|
Moldy foods (some molds produce toxins known as mycotoxins) |
Vomiting, agitation, incoordination, tremors, seizures, elevated body temperature |
*Small amounts of these vegetables, including powder and oil forms, are safely added to some pet foods for flavor
- To avoid an emergency trip to the veterinary hospital, pet owners should identify potential hazards in their home and store them well out of reach of curious cats and dogs.
- If ingestion of a potentially toxic substance is suspected, a veterinarian or animal poison control center should be contacted immediately. Availability of animal-specific poison control services varies from country to country. Check within your region for a resource before one is needed.

"No matter how much your pet begs, there are some people foods you should avoid giving your pet and make sure they are not left out where your pet could get them. Many pet owners are aware that dogs and cats should not eat chocolate. They also should not consume onions, garlic, grapes, raisins, raw yeast dough, moldy foods, coffee, caffeine-containing energy drinks or alcoholic beverages."
