awwwww....it could be nothing serious - Chanel did that a few months ago - they found hardly anything wrong after 2 different vet visits and was A-OK in a few days - problem was it went from one end to the other
and my little water crazed yorkie was actually sick of butt-baths that week - VERY Unusual for her lol -
Sending Grayson GET WELL WISHES !!! Keep going with the chicken - that's what my vet said too
