Skin problems can be related to even ear yeast infections. My Sandy had frequent yeast infections in one ear, my vet said it indicated he would be prone to be allergic and sure enough, he had a flare up right after that. Not related to thyroid, but a reaction to ant bites. Got any biting ants in your yard? Caused a mess on his tummy, itchy rash, sore spots, red skin, and swollen eyes. There are so many little critters in the grass. We've all got our paws crossed too, hoping the vet finds the solution to her weight problem fast. It's no fun feeling bum, especially in the summer. Here's wishing you a real happy and fun vacation. And don't fret while you're supposed to be having fun, your babies are only a call away.
