This sort of corresponds to my post re: Glaucoma--just researching this one and it is quite serious--I've got a call to my vet to do a follow-up protocol/diagnosis for Arias as I need to stay on top of this--I guess I should just be thankful for the 10+ years of no major vet bills with him and now have to prepare for the latter half of his life, whatever that brings--I'm recently divorced so this is a hard financial hit.
