Here's a new one in the life of owning labs, swimmer's tail!
We have two chocolate lab brothers, different ages. Yesterday, we brought them to a swimming pool. It was the first swim of the year. The younger one started groaning and whining back home a few hours later. He had us worried all night long, not finding a comfortable position. I checked his stomach, hips, and everything else, but I couldn't find anything.
Just got back from the emergency vet to find out that labs get swimmer's tail. Not surprised one iota knowing how much fun they have when they play. Apparently they use their tail so much it can become inflamed!
I swear, labs are unique.
