I am so very sorry.
Also, a little upset.
Not sure I got all the story right, but...
Did Otto get an exray and prednisone right away?
There was a delay w/ our pet getting the proper treatment as well.

It is late and I had to re-read this thread a few times. OMG! I almost passed out. The drama here.
Thank goodness Otto had that surgery! He must have a guardian angel!

I recall those Dodger's List folks helped me a lot as well our dauchshund had her surgery...also at age four. Good advice/good support.
My little "Fur Baby" (knock on wood/crossing myself and lighing a candle) made a complete recovery.

Saw on this site:
.
that Vitamin C might be good for inflamation/prevention. I've heard good things about qualified acupuncturists as well.

Sending you and Otto big hugs. I am keeping the faith.

I tell ya...this was one traumatizing thread.
