Sable still has the skin issues so I took her back to the vet last week. It was time for her annual shots so why not go and blow 3 bills on my baby. The Sulfodene oil that a couple of you recommended did seem to help some of the spots though. The vet is adamant that it is her thyroid and makes her prone to the skin issues. It just seems odd to me that it started all of a sudden early last summer. I'll give these meds a try for a couple of months and see if we get some results. Nevertheless, Sable is the most energetic of the 3 despite being 15 pounds over weight. Hopefully she'll look better soon.
