My 14month old lab, seems to be limping on one of his back legs, checked his feet and between toes and down both his back legs, no obvious site of injury or pain.
He's still willing to go on a walk, and weight bare (still jumping up) but there's a definate limp there.
More noticeable after he gets up from lying down/sleeping. Like he's stiff and old iykwim
He used to do it a few months back when he had a solid plastic bed, but thought it was because he'd trapped a nerve from lying with his legs over the edge.
But been okay recently. Just started again today.
Any ideas as to why? And at what point do I take him to the vet?
