I know 5.5 lbs is NOT big and I am not one of those nuts who just has to have a 1 lb. dog. The way Louies body looks leads me to believe that he is a chubba. He is very short and tiny but very bulky lately and he kind of waddles lately. Dont get me wrong HE IS ADORABLE! I just want him to be healthy and not have any problems. But thanks for the advice guys. I did not know that you were suppose to feed an adult 2 times a day and not 3. I dont give him a ton though. How much would be the right amount? I also have Bella who is about 5 months old, How much should I be feeding her? Thanks all!
