Hi thank you all for your imput. I have taken it on board but could not bring myself to rehouse either of the puppies. As it goes I am greatly relieved that I didn't as my puppies have calmed hugely and are turning into wonderful little dogs, yes with a very large amount of work. The aggression has subsided and with the multitude of books and other information I have been researching they are coming along beautifully. Last week they attended their first session of "puppy preschool" and were suitable behaved. They can now sit on command and have boundless levels of energy. I can't wait until they have their next vaccination as we have also been practising with our leash work. Looking forward to your continued support over the next couple of years. I didn't mention at the time of my first posting that I have had Staffys as pets for most of my adult life. I guess this has provided me with some valuable background information in the handling of them which may been the difference between keeping the two or rehousing one. Again many thanks
