I find this one very interesting. While dog food contains many of the same ingredients as cat food, never make the mistake of assuming that it is close enough. Only cat food is specially formulated to meet a cat’s nutritional needs. Cats require more protein in their diet than dogs do, as well as more B vitamins, niacin, vitamin A and fatty acids. Cats also require an amino acid called taurine, an essential part of their dietary makeup, as they cannot produce this substance themselves.
Onions and garlic in all forms — powdered, raw, cooked, or dehydrated — can destroy a dog’s red blood cells, leading to anemia. That can happen even with the onion powder found in some baby food. An occasional small dose is probably OK. But just eating a large quantity once or eating smaller amounts regularly can cause poisoning. Symptoms of anemia include weakness, vomiting, little interest in food, dullness, and breathlessness.
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.
