Do they know how or where Cowboy may have picked this up? I live in So Cal, so this concerns me a bit........... ...especially with both of mine having vet issues about every other month.
NO idea. We've gone over everything. The only dog he really is around a lot is Chester. I cook all his foods so we know it's not food borne. I don't take him to dog parks because he is SO gentle that other dogs could hurt him. All garden supplies are locked away....and everything is dormant so nothing there. As I said before, I guess one of the indicators of this is that there doesn't seem to be any cause...and it comes on fast. I don't know where in So. Cal the clusters are, but as they find out more, I'll post it. Hopefully UC Davis will be able to figure it out!!
