Ask and ye shall received.
I'll start it off.
Sometime last Monday night our 4 yr old yellow Lab Darcy sprained her tail. It was absurd.
That morning, I take her for her first walk and she was acting groggy and her tail was completely limp, which for Labs is very atypical (their tails are usually fully raised). Well, that morning she was acting like she was dying, so we got all freaked out and had to get a last minute vet appt. Well, my wife takes her to the vet. The vet does a short exam and tells us she's fine. Gave us some meds and Darcy was already starting to act like her usually bubbly self by that evening.
We still have no idea how she could have sprained her tail during the night when all she does is sleep. She must have laid on it wrong.
Below is said silly dog.
