Actually, dogs are omnivores like we are, and they LOVE fruit and vegetables usually. The only ones they shouldn't have are onions, raisins, and grapes.
My dog Molly would do ANYTHING, I mean anything, for chunks of apples... and she waited begging in the kitchen for scraps of zucchini.
Dogs should not eats orange, apple, banana, pineapple, strawberry, grape, and other fruits. Birds like crow, eagle etc.. are also not the food of dogs. Cats, rats, lizard, cockroach etc.. are also not the food of dogs.
There are many things a dog shouldn't be fed, here are just a few. Chocolate, cat food, fat trimmings, raisins, grapes, macadamia nuts, most dairy products, mushrooms, onions, and pits from fruits.
Usually dogs are given only dog foods. Dogs should be given salty items which cause itching to it and in turn rashes may form. Avoid giving too much of hot or cold thins.
