How Often Should You Bathe a Dog? Coat-by-Coat Guide

Many dogs only need a bath about once every three months, according to the ASPCA, with more frequent baths for dogs that spend a lot of time outdoors, roll in things or have skin problems. Coat type matters: oily or long, heavy coats may need more frequent washing, while short, smooth coats often stay clean for longer. Bathing too often, or with the wrong shampoo, can irritate the skin.

If your dog has itchy, red, flaky or smelly skin, talk to your veterinarian before changing the bathing routine. Some skin conditions need a specific medicated shampoo and schedule that only a vet can prescribe.

How often to bathe by coat type

These are general starting points. Your dog’s activity, skin health and your vet’s advice come first.

Coat type	Examples	Typical bathing interval	Notes
Short, smooth	Beagle, Boxer, Dachshund (smooth)	Every 2-3 months or when dirty	Weekly brushing removes most dirt and loose hair
Double coat	Husky, German Shepherd, Golden Retriever	Every 1-3 months	Brush out the undercoat first; dry thoroughly to the skin
Long, silky or continuously growing	Shih Tzu, Yorkshire Terrier, Poodle, Maltese	Often every 3-6 weeks, usually with grooming	Mats tighten when wet, so detangle before the bath
Wiry	Schnauzer, many terriers	Every 1-3 months	Frequent baths can soften the coat texture
Water-resistant or oily	Labrador, Newfoundland	Every 1-3 months	Natural oils protect the coat; avoid over-washing
Hairless or wrinkled	Chinese Crested, Pug, Shar Pei	Varies; ask your vet	Skin folds need gentle cleaning and careful drying

When a dog needs a bath sooner

Rolling in something smelly or getting into mud
Swimming in a lake, pond or the sea (a rinse with clean water helps)
Strong odor that does not go away with brushing
Contact with something sticky or potentially harmful on the coat

If your dog’s coat has paint, oil, chemicals or anything that could be toxic, do not try to clean it with household products. Call your vet or the ASPCA Animal Poison Control Center (US) for advice first, because licking the coat can make a dog ill.

Choosing a shampoo

Use a shampoo made for dogs. Human shampoos are formulated for human skin and can be too harsh. The ASPCA recommends a dog-specific shampoo.
Keep it gentle. A mild, unscented or lightly scented product is a sensible default for routine baths.
Medicated shampoos are a vet decision. Products for itch, infection or parasites should be used only on your veterinarian’s advice and exactly as directed.
Check flea-product timing. If your dog uses a topical flea and tick product, check the label or ask your vet how long to wait before or after bathing. Our flea and tick prevention guide has more.

How to bathe a dog, step by step

Brush first. Remove loose hair and work out tangles and small mats before the coat gets wet. Large or tight mats are best left to a groomer.
Get everything ready. Shampoo, a cup or handheld sprayer, a non-slip mat, several towels and a few treats should be within reach before you bring your dog in.
Check the water. Lukewarm, not hot. Test it on your wrist.
Wet the coat thoroughly, starting at the neck and working back. Keep water out of the ears and eyes.
Lather gently with a small amount of shampoo, massaging down to the skin. Use a damp washcloth for the face instead of pouring water over the head.
Rinse completely. Leftover shampoo can irritate skin. Rinse until the water runs clear and the coat no longer feels slippery.
Dry well. Towel dry, then let your dog shake. If you use a hair dryer, keep it on a cool or low setting and keep it moving. Thick double coats need drying right down to the skin.
Reward. Offer treats and praise throughout so bath time becomes something your dog tolerates calmly.

For dogs with facial wrinkles, clean the folds with a damp cloth and dry them carefully; moisture trapped in skin folds can cause irritation.

Making bath time less stressful

Practice short, dry visits to the tub with treats before the first real bath.
Use a non-slip mat so your dog feels secure.
Keep sessions short and calm, and avoid forcing a frightened dog.
If your dog panics, struggles hard or shows signs of aggression, stop and ask a professional groomer, your vet or a certified behavior professional for help.

Bath time is also a good moment for other grooming tasks such as checking the ears and trimming nails, since nails are softer after a bath.

Between baths

Regular brushing does most of the work of keeping a coat clean. It spreads natural oils, removes dirt and loose hair, and helps you spot lumps, ticks or skin changes early. For heavy shedders, see our guide on dog shedding. Wiping paws after walks and spot-cleaning muddy legs can also stretch the time between full baths.

When to call the vet

Contact your veterinarian if you notice:

Persistent itching, licking or chewing at the skin
Redness, rashes, scabs, sores or bald patches
A strong odor that returns quickly after a bath
Greasy or heavily flaking skin
Head shaking or smelly ears

Bottom line

For many dogs, a bath every few months is enough, with brushing in between. Dogs with long, oily or high-maintenance coats, or active outdoor lifestyles, may need more frequent baths. Use a dog shampoo, rinse thoroughly, dry well and ask your vet about any skin problems rather than bathing more often.

FAQ

Can I bathe my dog every week?

Weekly bathing can dry out the skin for many dogs. Some dogs do need frequent baths for medical reasons, but that schedule should come from your vet, along with the right product.

Can I use baby shampoo on my dog?

It is gentler than many human products, but it is still made for human skin. A shampoo formulated for dogs is the better choice.

When can I give a puppy its first bath?

Ask your vet, especially for very young puppies, which can get chilled easily. Until then, spot-clean with a damp cloth and keep the puppy warm and dry.

Why does my dog still smell after a bath?

Damp undercoat, leftover shampoo, dirty bedding or ear and skin problems are common reasons. If odor returns quickly, have your vet check the skin and ears.
