She was probably hurting when she bolted for the truck.
It's o.k. for her, she'll be happy as a lark as a family pet, and with a mild case as long as she's not pushed to the limit she won't be in any discomfort that a low dose of NSAID (rimadyl or similar) won't relieve. I know it's frustrating for YOU!
Be sure to talk to the breeder, you may be able to get something back on her, and at a minimum the breeder needs to know that this cropped up.
We're having Ruby X-rayed after she turns 2 in August, and we'll decide whether to spay her after that. Of course I'm nervous - she sure doesn't display any symptoms but I'll feel better when that hurdle is crossed.
Bob did talk to the breeder - I guess what’s going to happen is that they will send us another pup. I am so upset about Belle, we will have her checked again at 2yrs old - hopefully it will remain mild (it’s in one hip only) and she will be pain free and able to stay active. I had to have a german shephard put down at about 8mos old many years ago - she had it so bad she was falling down going around corners. Her breeder had guaranteed no HD - I so wanted him to develop it himself.
