Well for starters i wouldn't chain him up this is a big no no with this breed escpecially when his original owner has left him pitties can big sooks so he will fret for his old owner, so i suggest a blanket on your floor in your bedroom for at least a week this will help the dog to understand that you won't leave him otherwise when your out he may become distructive, the best way to stop him from chewing things making sure he has a lot of things to chew on such as : they love the cheap chews bones from $2 shops, pigs ears (dryed from the supermarket) and always make sure there is a contant supply of dry food for him . They need lots of TLC and believe me you will get that back ten fold,pitties are very affectionate when treated right.they need to (speaking from personal experience)be treated like a child chastised properly for being naughty,rewarded when they are behaving.
