My 10 year old sprocker has suddenly started shaking his head, and pulling at his ear. We've been out for a walk, come back and he's had his food. It started quite suddenly and he's clearly uncomfortable as he can't settle.
Any ideas what it might be? His ear looks ok, no swelling or redness. I was wondering if he's got a bit of grass seed or something stuck. Would taking him for a quick swim help? We are close to a river with a shallow bit for dogs
