I just got him last night, hes a purebred Lhasa Apso, 7 weeks old. I got him around 7pm last night and he really is lazy and fat !! But thats not what worries me, i dont know if its just him being exhausted or stressed but he hasnt gone potty since ive had him.. he eats just fine and drinks but other then that he just wants to whine or cuddle.. any thoughts? I already made an appointment to go have him checked out at the vet but they cant see me for a couple of days.
