I have him on Castor & Pullox's Natural Ultramix puppy food. I combined his old food with the new food for about 9 days - until I ran out of the old (he didn't really eat then, either). I have been mixing the food with water/chicken broth for about six days (per some suggestions on this site) and he has increased his eating a bit. He eats at 7am and 7pm, mostly because the breeder only fed him twice a day and the vet said to stick to it. I don't know if it would affect his eating - but he doesn't have worms, as I have been checking each time he goes to the bathroom.
I think its mostly that he is very easily distracted, but I am worried because I can tell he has lost a little weight since he has been with us. He isn't sluggish or anything, though. Still a bundle of energy!
Thanks for any advice.
