Good Afternoon and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
Most likely Coco has injured a disc in the vertebrae at the base of her tail or close to the tail. This can happen when playing hard or by some form of trauma or just by moving the wrong way. The best thing to do for now is to give Coco aspirin at 5 mg per pound every 12 hrs to decrease the inflammation that is causing her this pain. Try to keep Coco as immobile as possible so the disc or bruised area has a chnace to heal. Certainly, if this continues, have your vet examine her but chnaces are, with such a young strong lab, she will come out of this quickly.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.
Sincerely, XXXXX XXXXX
