thanks for all the replies! he knows his name, Oscar. he responds every time with his head moving over. i think i accidentally taught him that coming over is me ignoring him...and i feel terrible.
he's a maltese/pekingnese/shitzu.
by take back, i mean take it home, ie my home. the vet said it was ok to take it back to "my" home.
at the breeders, he was also kept inside. he sleeps in his pen, on his bed, with a puppy pad next to it.
i feed the puppy 4 times a day, mixture of royal canin + wet food, to wean him fully into just Dry food/biscuits/royal canin.
