its bouncing mate ?first id stop it jumpng at you mate tell it down might even have to scruff it a few time until it stops youll end up blacked eyed if not sooner or later ?then it wont do it to strangers the winding dogs up etc is hard unless a dog knacks it or it will do that its bouncing thats all
the jumping about couch to couch is hard unless you crate it until its been walked tired out
the lads dog whisperers on here so far will have spaniels shepherds collies etc they are alot easier to sort out ?good luck?
