Oatmeal cream pies are typically made with ingredients that are safe for humans to consume, but feeding them to dogs might not be the best idea. While oatmeal itself is generally considered safe for dogs and can even provide some nutritional benefits, the other ingredients in oatmeal cream pies, such as sugar, butter, and potentially artificial additives, are not well-suited for a dog's digestive system.

High sugar and fat content can lead to gastrointestinal upset, including vomiting and diarrhea, in dogs. Moreover, many commercially produced baked goods contain ingredients like chocolate or xylitol (a sugar substitute) that are toxic to dogs.

It's always best to stick to dog-specific treats or foods that are safe for dogs if you want to give your furry friend a treat. If you're looking for a safe and healthy treat for your dog, there are many dog treats available on the market that are formulated to meet their nutritional needs. If you're unsure about whether a specific food is safe for your dog to eat, it's a good idea to consult with your veterinarian before offering it to them.
