sounds like one crazy ass dog lol but like sammc said there are loads at a rescue centre that need good homes I rescued one staffy bitch from our local centre and she is the most fabulous dog I have ever owned but as long as the pup is loved then go for it a dog is always pleased to see you always there to give you a hug, but be warned puppies need lots of attention dedication and hard work to get them trained I had a hell of a job training my last pup to go outside for a wee but we got there in the end.
Good luck and enjoy your pup should you decide to buy him/her
