If Dasher does Have hip displaysia, he's probably uncomfortable and should probably see a vet as soon as possible. I don't think that you would Have to make a big descision right there. Thats just my opinion. You could bring him in, see what the vet says and bring Dasher home and think about it at home. There are a lot of drugs that dogs can take to help them with hip displaysia you don't always have to Put them to sleep. It's just a lot of times people don't want to deal with it.
