I recently bought home an alaskan malamute pup. He is the cutest little thing, until he is put away at night. He has not had his second set of shots so obviously I can't put him outside and he is not properly toilet trained yet. He howls until he loses his voice. I have tried everything- clocks, hot water bottles, radio etc. nothing works. I know it is expected in the first few days of bringing a new pup home, but it is just getting excessive. Does anyone have any advice?
