My boxer Bertie has started having episodes of Idiopathic Head Bobbing. He is 2.5 years old and the first one was on Sun, 14 Oct then on Fri, 19 Oct, Sat, 20 Oct and Sun, 21 Oct. I took him to the vet and they've suggested blood tests and an MRI scan but as he's not insured we've not gone down this road. We feed him IAMS dry dog food and my housemate works in a restaurant and brings him home meat everynight; could it be a build up of protein that's causing his head to bob? I'd be grateful for any advice.
