Remember that all dogs are made different. It depends on the size, breed, and dog on what is toxic to it and what is not. But one thing for sure is that its not worth the risk of losing your furry, 4-legged friend. There are some foods that are good for dogs like a little bit of yogurt (non-flavored) can help the digestive system. Or a few droplets of olive oil mixed in with their dog food can give them a glossier coat. But always consult your vet when introducing a new food to your pet, and watch carefully after feeding it to your pet to make sure there is no allergic reaction. Which could include scratching, biting, chewing or constant licking of the feet, etc. Just watch for unusual behavior. Happy tails! (ha lol)
