Sal, I know what it is like moving from one breed that is totally calm then deciding to go with something that is completely different the transition from moving from 'British' Bulldogs then deciding to go with American Bulldogs & Olde Tymes was quite a shock for us & at times found ourselves litterally pulling our hair out and wondering the exact same things ourselves.

Almost seven years on (How time flies!) I've learned to appreciate the dogs, however naughty they are.

I can see the OP is desperate for their puppy to stop but I think they are forgetting that he is just a puppy it is behaviour that he may not carry on into his adult life - obviously I don't know all the circumstances but if they wish to keep him all it is going to take is patience and time sadly I can't help feeling they are at the end of their tether going by some of the content that is written in their posts and in instances such as these, you always have to think of the dog - be totally selfless and the best advice that I can give them right now is passing him on to someone with more experience of the breed.
