Another one who has been there done that with a dog. My 1st GSD - well before testing was available - started off being 'not quite sound' about 7ish years, gradually got less sound and was finally diagnosed with the hideous condition. he was still on his feet and walking - after a fashion but lost bowel control and after about 2- 3 days when he was SO upset that he was doing the unacceptable - in HIS mind - he was really depressed.
He was never going to improve only just get worse so we made THE decision and said goodbye to him aged 8 ¾.
I'm blubbing just writing this after 18 yrs.
