Foods dangerous to dogs

A number of common human foods and household ingestibles are toxic to dogs, including chocolate solids (theobromine poisoning), onion and garlic (thiosulfate, sulfoxide or disulfide poisoning), grapesand raisins (cause kidney failure in dogs), milk(some dogs are lactose intolerant and suffer diarrhea; goats' milk can be beneficial), nutmeg (neurotoxic to dogs), macadamia nuts, as well as various plants and other potentially ingested materials.

Dogs are prone to have adverse allergic reactions to food similar to human beings. The most common symptoms of food allergies in dogs include rashes, swelling, itchy or tender skin, and gastrointestinal upsets such as uncontrollable bowel movements and soft stools.Certain ingredients in dog food can elicit these allergic reactions. Specifically, the reactions are understood to be initiated by the protein ingredients in dog food, with sources such as beef, chicken, soy, and turkey being common causes of these allergic reactions. A number of "novel protein" dog foods are available that claim to alleviate such allergies in dogs.
