How much food are you trying to get into him? I suspect it might be too much and that’s why he doesn’t want to finish meals.
Since he came from a pet store that usually means he is from a puppy mill, so his growth may be permanantly stunted because his mother didn’t necessarily get what she needed when she was pregnant. It drives me nuts that ignorant people keep supporting these evil people by continuing to buy puppies from these places. I won’t buy ANYTHING from a pet store that sells these puppies. They need to be driven out of business too. I know you said you didn’t get this dog from the pet store yourself and that you are aware of the issues, but I sure hope you got a chance to educate the ones that did support this barbaric behavior.
