I have a 2 year old yorkie and last october he started walking funny and holding his head to one side. It turned out to be a stroke. He was in hospital for 16 days as he was very ill. We now have him home and he is playing with the other yorkies and with his toys. He is so lucky that we got him to the right vet as two other vets had seen him during that week and they did not notice he had taken a stroke. Hope shadow gets better soon.
