Puppy and near adult play
I just got a new 12 weeks old German Shepherd puppy and a 1 year old German Shepherd teenager.
My question concerns the type of play I should expect between the two. It seems that the 1 year old is more interested in playing than the puppy. The teen will run after him in the backyard and in the house and scruff him until he yelps at which point the play will pause for a few seconds. The puppy doesn't seem too shy about playing and he will often snap the side of teens' nose and ears. I guess my question is: when is it too much? Do you let adults and puppies play? If the puppy yelps but there is never any scraps or cuts, should I let them go at it?
