Hi Louise.
well I had a Jack Russell with it, diagnosed at 3yrs, lived until 15yrs, NEVER had a collar on, only a harness or run loose. My sisters Pomeranian had it at 11, it really was bad in her and coupled with a heart complaint it ultimatley killed her. I didn't have my Jack operated on and she really wasn't too bad at all, if your dog is as bad as you say she is, then if she were mine I would go for it, the prospect of finding her suffercated is not nice. Hope she gets well.
Dawn.
