Our 11 y/o aus shep? mix is displaying signs of rear leg lameness. Difficulty getting up from lying down and getting onto the couch were what we noticed first. She has developed a limp and drag when walking which seems to be worse on the left side with occasional tremors in her leg when standing. She’s not as high strung all the time like she used to be, but her personality has not changed. And we have seen absolutely no signs of pain. She will still chase the squirrels in the back yard and won’t yelp if she falls because she can’t run well anymore. Occasional incontinence (not urinary) and walking with an uncomfortable squat while defecating are also new. We have tried a bit more exercise but dragging her left foot every 2 or three steps on the concrete has worn her nails down to the quick. And we can’t get her to the park as often as we would like. I know we need to get her to the vet but I would like to have some idea what we are dealing with, what questions to ask, and what questions the vet might ask us. Thank you.
