Have a question about Dio (my 1 year and 5 month old dog). We go to the off-leash park every Sunday and are there for about 1hr-1h 1/2. Dio's left rear leg seems pretty stiff after an hour there. He doesn't bend it when running. The other 3 are, just that one looks weird. Could it be something serious? I was thinking of giving him glucosamine or something like that.
Do you think it could help? What could be causing it?
