Well mate, the rest of them on here are right , maybe a trifle harsh ,but I'm sure they are thinking of the pups welfare.
Just bond with it for now ,and DO NOT DO ANY JUMPING, with it however small the obstacle ,its bones have not knitted yet ,you will f**k up its pasterns if you continue, plenty of time for that.Get it use to coming to call ,and gradually introduce a soft toy on a string ,as a teaser.Don't rush the first year is all about making the deposit in the bank to draw on for the future.ATB Inan.
