he is just gorgeous!
what breed is he? looks like rottie colouring. you do forget what hard work they are but so worth every bit of it.
not many of my dogs were too happy when they had to deal with a`new, boisterous puppy swinging on their tail but the pup will soon learn how far he can go and they will get along great.
you will have to keep posting pics so we can watch him grow.
