She could be like the foster I have. He had a dental last year and also two hernia operations. We knew about the AAI and took the chance because he was such a mess.
He just had surgery again a couple of weeks ago because the hernia is still there and the bladder got trapped....the surgeons were very concerned about doing the surgery, but Sammy once again showed how tough he is! There is nothing we can do for his AAI because he has way too many other issues and they are afraid of a snowball effect. I talked with them about another dental as he is in need again; but they are not thrilled about it...and it does frighten me.
BUT...he might do just fine. He has been like your Cassie...very tough!
Oh, and Sammy is probably double Cassie's age, so he has lived a very long time with all of these things. Even the neurologist was shocked when they did all of the tests and found all of the things that are wrong with him. I asked her how he lived this long and she said they had been talking about that all day. So...you just never know.
