True! This goes both ways, and applies to shelters too! Make sure you're getting all the facts about the dog in question. Ask for vet history reports, and that they go over them with you first.
When I adopted my red nose boy, my boy friend and I were interviewed in depth before being approved. However, the shelter/foster mommy were less than forthcoming with us. I give them the benefit of the doubt in that they really needed him to find a good home, but my baby boy had an expired rabies certificate, out of date boosters, a recent case of Lymes Disease, and a problem with his paw pads, making long walks very painful, and unable to be completed. Not of which I was made awake of. Not that I wouldn't have wanted him anyway (I was in LOVE with him) but it sure would have saved me a pretty penny at the vets office trying to figure out what was wrong with him. Not to mention, have you ever tried carrrying a 65 pound Pit Bull half a mile down a hiking trail? Not fun!! My feet hurt worse than his did by the end of it!
