How old is she? I would use that as a guide to making decisions about tests.
What does meat have to do with cutaneous vasculitis?
Kibble is enough. It should have all of the nutrients needed.
Why can't the vet view her ear? As for cleaning, have your vet do it!
Nystagmus is neuro and as Ellie May suggested, neuro would be a great option. If it is not possible, a general vet can do basics ... and often if a client is limited on funds or if a pup is very old and testing isn't going to change the plan going forward, prednisone can be helpful. My DIL had a pup who was 15 and she suddenly went blind one day and was stumbling around. She ended up putting her on prednisone and she had another 6 great months with her. They were sure it was a lesion...surgery was not an option.
So...cannot hurt to try the pred IMHO |
