My goldendoodle Griffin started limping about 2.5 weeks ago on his left leg during his morning walk. At the time he was about 9 months old. I didn't notice him fall at the time. After numerous attempts at trying to find where the pain was localized - he didn't react too much to poking and proding - we thought that it was his left shoulder. He didn't get better, so I took him to the vet. The vet agreed and thought that Griffin was giving her the most resistance to shoulder movement. She also took X-rays but found nothing - an expensive nothing. Griffin has been on anti-inflammatory, painkillers, and rest for about 1.5 weeks, but he hasn't improved. The vet suggested taking him to a specialist. After researching online, my guess is OCD, but I wondered if anyone else had experience with this and had any advice for me going forward. He limps most dramatically after lying down, then it will typically improve slightly if he's walking around.
