Good luck with him, he looks a handy wee dog and well done for giving him the chance of a better life. It is a shame that dogs are treated like that, imagine these people are probably bringing up kids as well, dear help the kids, eh? At 7 months he is still a pup and if all he has seen is the inside of a shed, being in a house must be full of such excitement and tempting things to chew. Buy him a crate to stay in to keep the peace while the bitch shows him who the boss is!
