Thanks for the name Gina

now I wont look like an idiot when talking about it!!
Yes Chubby, her brother has severe HD and not long after since she was his litter mate I had her xrayed also...just a standared xray not one that is sent off to be graded, just for the orthopedic vet to see to make sure she was ok.
I didnt think about her elbows though and I didnt realize that I should because she has never shown any signs at all of any problems with that. Would she show any signs of problems if there is one, like Chubby did with his HD?
I dont want her to get hurt or cause her any problems for the future as I see what all time, money, and most of all pain these problems cause by taking care of Chubby.
I have taken and retaken advanced ob a bunch of times and we even did a ring class. Since she is such a hyper dog, jumping over the couch when trying to jump on Chubby (playing) and she loves her cheapie tunnel I thought agility might be fun for her. I was taking this class because its only a "introduction" to agility not a advance or novice class. I also thought it would be something different for her to do.
She does really well as far as listening to me most of the time, but with that said when it does happen I feel more secure with the martingale on her.
Maybe after this class, if I stay in it, Ill try something else.
Thanks for all the advice yall have given!!
