Zada is 8 pounds (a pound overweight due to a thyroid condition were working on right now) and Azrael is 6 pounds. They each get 1/4 of a cup of food in the morning and in the evening. For lunch they get non-fat yogurt and fruit. I don't give them "snacks" but maybe twice a week, but they get femur bones to chew on every day.
Garlic helps to tone up the digestive tract and discourage worms and other parasites, including fleas.
All the grocery stores sell ground turkey and chicken. Fowl is ok for the dogs because they are not pumped full of hormones and other chemicles.
I do want to add that there are those who say feed raw meat and those who say cook the meat. Frankly it's up to you. Personally, I'll stick to cooking it. Better safe than sorry is what I live by.
