My Great Pyr has been tentatively diagnosed with discoid lupus. I say tentatively, because the vet is judging by symptoms. If she doesn't respond to the medications that the vet prescribed, a biopsy will be done on some skin tissue. It's not at all common for Pyrs to have it. My main concern is that the condition is made worse by exposure to the sun, and my dog is outdoors with the sheep most of the day. I was wondering if anyone has or knows of a Pyr or another type of lgd with this condition and how they managed it.
