I have 3 doggies and feed this way. One is sick, so he gets a Flintstones vitamin and a fish oil daily. They don't like them so I put them in his food and top it with yogurt or pumpkin. He has out lived predictions on life expectancy from 2 vets. I don't know why, but I do not question this. It is just good to have him.
They get raw or cooked veggies not laced with sauces. Some raw meat, if i give them cooked meat, i rinse it. They do not need the salt and garlic is a no no. They eat lots of fruits, strawberries, cantaloupe, cauliflower, beans and tomatoes. One likes lettuce, 2 like olives.
I encourage anyone to feed this way, even to supplement store bought food.
