I usually feed my puppies about a cup of puppy beneful a day. We have five chihauhau dogs in which we breed them. We have mom and dad two long hair sisters and now we have a new puppy from their last litter. We are very happy with beneful puppy dog food.
You should feed a puppy according to the weight that he/she is now and the weight that he/she will be when they are grown. The foods that have the highest content of chicken or lamb are the better foods.
You need to make sure that you are feeding your puppy at least twice a day. You should make sure that you are not feeding your puppy food that has corn gluten in it, either.
