How often should you bathe a dog?

"How often should I bathe my dog?" sounds like it should have a simple answer, but it doesn't — it depends on your dog. Here's how to get it right, and how to pick a shampoo.

The short answer

Bathe your dog when they're genuinely dirty or noticeably odorous rather than following a fixed calendar. Too-frequent bathing or unsuitable products may dry or irritate the skin; frequency varies with coat, lifestyle and health.

A rough guide

Most healthy dogs need only occasional bathing when they are dirty or noticeably odorous. Frequency varies with coat, lifestyle and health; dogs with skin conditions should follow their veterinarian's plan. Regular brushing between baths does more of the work than water does.

Never use human shampoo

Human skin and dog skin have different pH, so human shampoo (and even baby shampoo) can dry out and irritate a dog's skin. Always use a shampoo made for dogs.

Choosing a shampoo

The right one depends on your dog's skin and what you're trying to do:

• Gentle / sensitive — a mild, fragrance-light formula may suit dogs with easily-irritated skin.
• Oatmeal — often chosen for dogs prone to dry, flaky skin, as it's soothing.
• Deodorising — for the dogs who find the smelliest thing in the yard and wear it home.

Whatever you pick, read the label and follow it. If your dog has an actual skin problem, ask your vet which shampoo to use rather than guessing.

Medicated shampoos are a vet's call

Medicated shampoos are condition-specific. Use one only on veterinary advice, following its label and the prescribed contact time and frequency.

How to bathe well

• Use lukewarm water — comfortable on your own wrist.
• Lather gently, avoiding the eyes and inside the ears.
• Rinse thoroughly so residue does not remain.
• Towel-dry (and go easy with a dryer — warm, not hot), especially on a thick coat that stays damp.

When bathing isn't the answer

If your dog stays itchy, smelly or flaky no matter how you bathe them — or seems worse afterwards — stop using the product and arrange veterinary advice; the bathing frequency or product may be contributing, and more washing may worsen the irritation. More in itchy or flaky skin in dogs.

At Tidbit: in our Grooming range, a gentle option like U Groom Sensitive Shampoo, an oatmeal one like Dermcare Aloveen Oatmeal Shampoo for routine cleansing of normal or sensitive skin, or an everyday wash like Fido’s Everyday Shampoo may suit — always read the label.
