Here is a great list I came up with of the foods your dog should never eat.
No matter how good you think the guacamole is, you shouldn’t give it to your dog. Avocados contain a substance called persin. It’s harmless for humans who aren’t allergic. But large amounts might be toxic to dogs. If you happen to be growing avocados at home, keep your dog away from the plants. Persin is in the leaves, seed, and bark, as well as in the fruit.
Milk and Other Dairy Products
On a hot day, it may be tempting to share your ice cream cone with your dog. But if your dog could, it would thank you for not doing so. Milk and milk-based products can cause diarrhea and other digestive upset as well as set up food allergies (which often manifest as itchiness).
Dogs should not eat macadamia nuts or foods containing macadamia nuts because they can be fatal. As few as six raw or roasted macadamia nuts can make a dog ill. Symptoms of poisoning include muscle tremors, weakness or paralysis of the hindquarters, vomiting, elevated body temperature, and rapid heart rate. Eating chocolate with the nuts will make symptoms worse, possibly leading to death.
Persimmons, Peaches, and Plums
The problem with these fruits is the seeds or pits. The seeds from persimmons can cause inflammation of the small intestine in dogs. They can also cause intestinal obstruction. Obstruction is also a possibility if a dog eats the pit from a peach or plum. Plus, peach and plum pits contain cyanide, which is poisonous to both humans and dogs. The difference is humans know not to eat them. Dogs don’t.
Kitchen Pantry: No Dogs Allowed
Many other items commonly found on kitchen shelves can harm your dog. For instance, baking powder and baking soda are both highly toxic. So are nutmeg and other spices. Keeping food items high enough to be out of your dog’s reach and keeping pantry doors closed will help protect your dog from serious food-related illness
If Your Dog Eats What It Shouldn’t
Dogs explore with their mouth. And, no matter how cautious you are, it’s possible your dog can find and swallow what it shouldn’t. It’s a smart idea to always keep the number of your local vet, the closest emergency clinic, and the ASPCA Animal Poison Control Center (888) 426-4435 — where you know you can find it in an emergency. And, if you think your dog has consumed something that’s toxic, call for emergency help at once
