I wanted to let people know about this. My friend's dog (Summer) went swimming in a bay for a long time enjoying her day at the beach. When they brought her home they saw that something was wrong, her tail was down and she was panting. It turns out that Labs for one love to swim so much they pull a muscle in their tail. It is very painful and they need to be on pain killers and need to see your vet, it's not life threatening but you need to see the doc for meds. It takes at least a week to get back to themselves again. I thought to post this because our dogs love the water, so be aware.
I doubt Neely will suffer from this as it would be more likely to happen if he had to straighten his tail out for long periods of time. His curls back over his back more like a shitzu or something.
