Case Study: The Lovable Labrador
Meet Gus, the happiest most enthusiastic lab around! Well known for a tail that never stops wagging! However, one odd day, Gus was noticed to be looking unusually serious. His tail hung straight and low, he was reluctant to sit and lacked that characteristic labrador energy.

Gus’s family mentioned that he had spent the previous day playing, running, and ended the day with a bath— a combination that can be a perfect recipe for a condition called Swimmer’s Tail. While the name may sound lighthearted, the discomfort is very real for dogs who rely on their tails for balance, communication, and enthusiasm.
What Is Swimmer’s Tail?
Swimmer’s Tail is an inflammation of the muscles at the base of the tail. It is most often seen in active dogs, especially sporting breeds like Labradors.
Common triggers include:
- Vigorous exercise
- Swimming, especially in cold water
- Extended periods of crate rest
- Overexertion of the tail muscles
- Bathing, particularly when combined with chilly temperatures or prolonged tail movement during drying
Signs owners may notice include:
- A tail held low, straight, or slightly out from the base
- Pain when the tail is touched
- Difficulty sitting comfortably
- Reduced or absent wagging (always alarming for Labrador families)
- Mild swelling at the tail base

Although the condition can look dramatic, it is not associated with fractures or neurologic issues, and recovery is typically very good with appropriate care.
Gus’s Treatment and Progress
Gus’s exam and history were consistent with Swimmer’s Tail.

His treatment plan included:
- Laser therapy to help decrease inflammation and promote healing
- NSAIDs to relieve discomfort
- A few days of rest and restricted activity
Gus responded very well, and within a few days his signature wag returned — first cautiously, then enthusiastically, as if he had quite a bit of wagging to make up for.
What Pet Owners Should Know
Swimmer’s Tail is a temporary and treatable condition, but because it can mimic other causes of tail pain, it’s important to have your pet evaluated promptly. If your dog suddenly stops wagging, seems uncomfortable after swimming, vigorous play, or even after a bath, our team can help determine the cause and provide effective treatment.
