Chocolate is one of the most toxic substances for dogs, as it contains methylxanthines, which are stimulants that can stop a dog's metabolic process. Grapes and raisins can also cause kidney failure in dogs, with only a small amount being enough to make them sick. Symptoms of this include vomiting, becoming slow and depressed, and in extreme cases, abnormal heart rhythms, seizures, tremors, or death. Sugar substitutes are also not beneficial for dogs, as they do nothing nutritionally and can lead to cravings for sugar.
It is best to give them whole-grain treats such as fresh fruits and vegetables instead. Raw meat and fish can be contaminated with bacteria such as E. coli, which can cause food poisoning, while some fish may contain a parasite that causes “fish disease” or “salmon poisoning disease” (SPD). Corn and rice are often used as fillers in dog food, but they can cause chronic conditions such as gas, bloating, and diarrhea.
Grain-free foods have been linked to fatal heart problems in dogs, while nitrogen-rich plastics have been added to dog food to make it appear to contain more protein. Watermelon is safe for dogs to eat but the seeds should be removed as they can cause intestinal obstruction. Milk should also be given in moderation as some dogs may be lactose intolerant. Avocado should be fine if eaten in small amounts but keep an eye on your dog just in case.
Skin should also be avoided as it is difficult for your dog to digest. When choosing a dog food for your pet, look for healthy ingredients such as naturally sweetened fruits and vegetables and meats with hearty names such as chicken. If your dog has certain allergies, it is best to avoid peas or lentils as the main ingredient.
