At least that's what the ortho vet strongly suspects. The last one was 11 months ago. I started playing fetch again with him about 2 months ago ~ only for very brief periods, only on level ground, only a couple times a week. And he's been fine.
Until I got home from work today and he was doing that tucked tail/hunched back thing. Dr. Gurevitch said that if it happened again we should do some kind of imaging, to see if it's a disk problem. Sigh.
On leash only until we find out more, poor boy. Will keep you posted, please send good thoughts.
