i've got a very active 7week old staff, there are a number of games we are playing with him at the moment, but just wondering how long we should play with him as due to his age i'm sure there will be a time limits in terms of his physical activities?

Hi,
I personally wouldn't be playing for anymore than 5 - 10 minutes at a time with your youngster, especially physical games, just in case.  I could be wrong, but I would tend to treat physical games the same as walking i.e not too much to start with and gradually build it up as your pup gets older.  I'm no expert mind you, but that's what I've done in the past and I find that when pups play with older dogs, this tends to be about the time limit!
