Grooming and coat
How should I rinse my dog's coat after swimming in the sea?
Last updated 23 September 2026 · How we write and check this
Short answer
Rinse thoroughly with fresh, lukewarm water as soon as possible after a swim, paying particular attention to the belly, legs, and paws where sand and salt collect most. Left to dry in the coat, salt draws moisture out of the skin and can leave it dry, flaky, or itchy within a day or two.
Why salt left in the coat causes problems
Salt is hygroscopic, meaning it pulls moisture out of whatever it touches, so salt water left to dry naturally in a dog's coat can leave the underlying skin drier than usual, sometimes leading to flaking or increased itching over the following day or two if it is not rinsed away.
A practical rinse routine
A hose or portable water container at the beach, used for two to three minutes focused on the legs, belly, and paws, removes most of the salt and sand before the drive home. A fuller shampoo bath once home finishes the job, particularly useful after a longer swim or a very sandy beach.
Paws deserve extra attention
Sand trapped between the toes and pads after a beach day can cause soreness or irritation if left, so checking and rinsing paws specifically, even if a full body rinse is not possible, prevents the most common source of post beach discomfort.
Key takeaways
- Salt left to dry in the coat pulls moisture from the skin and can cause flaking or itching within a day or two.
- A quick rinse focused on the belly, legs, and paws right after swimming removes most of the salt and sand.
- Checking between the toes for trapped sand prevents a common source of post beach paw soreness.
