dogs will learn by being told off by other dogs. if your puppy gets too giddy then the older one will tell him off by giving a quick moany snap but not biting or being nasty just warning its how puppies learn. if he gets too giddy though and the other dogs start to get fed up with him then it time to stop the play and part them for a few minutes to calm down. my lemmy was always getting told off by other dogs till he learnt so dont worry about it oo much. if he gets too giddy and mouthy with you then just make a yelp sound or shout oww!!! and he will take this as a warning sound and will eventualy stop that too. its all in the training and socialising that our dogs learn and puppies especialy learn by playing with older dogs

Agree with Julie. Suki is still getting told off by some of the older dogs. Laerning about body language is important. Staffys tend to play rough so you will have to know the difference between play and aggression. Here is a link that should help
