Millicent, I’ve had a similar experience as yours though probably not as dramatically obvious. I have a cat with feline hyperesthesia syndrome and dry food triggers violent outbursts; he self-attacked himself to the point of bleeding and removing dry food from his diet completely has dropped the episodes. Occasionally he’ll flare up; a chiropractic adjustment or acupuncture does the trick. I have no idea why he has this or what causes(d) it, but I’m just glad I’ve found a link to help keep the episodes down and keep him from being a bloody and miserable mess. Best to you and your pup.
