Experiences adopting a dog?

Would like to hear about some peoples experiences adopting a dog , specifically pitbull/bully type dogs once there adults . I have experience with the breeds but only when dealing with them from puppy age on up . Found a couple of good shelters here town/ close by that have dogs but most are older 1yr + all of them try to be truth or as much as they can about the dog backgrounds etc, but I've always weary of not knowing the full background on a dog



Is there any sign you looked for before adopting?



would any body caution against it?



FYI am all for getting a pup from a reputable breeder but my wife is pushing for adoption
