Can anyone advise? I have a GSH pointer crossed with flat coat retriever. He is a very fit 10 year old but has recently suffered with acute pain at the base of his spine where it meets his tail. Suspecting arthritis I treated him with Youmove which certainly helped after a week or so. A month on and the pain has returned restricting his gait whilst walking/running. With the pain he is downbeat and normal exercise has been reduced which probably doesn't help his mood. He is eating normally so I am considering pain relief but he suffers from grand mal seizures infrequently.
