This Is probably a common age old problem by now regarding my 3 month old pup jack who keeps mouthing/nipping most of the time it seems to be in play but now and again say if i remove him from the couch or try to groom him with a brush he nips at my hands and snaps in the air in a rebelious way i know this is natural for pups but it seems to be getting worse with the nipping.
I've read a few articles and the consensus seems to be with time outs stop play method but we have tried this now for over month and it hasn't stopped or even reduced his actions we have also tried yelping and growling
