How long can you go without bathing your dog?

As a dog owner, you want to keep your furry friend clean, healthy, and smelling fresh. But determining the right bathing schedule can be tricky. Bathing too often can dry out your dog’s skin and coat. But waiting too long between baths can cause them to get dirty, greasy, and smelly.

So how long can you really go without bathing your dog? There are a few factors to consider when deciding on the ideal bathing frequency for your pup.

How Often Should You Bathe Your Dog?

Most dogs only need to be bathed every 4-6 weeks or so. However, there are some exceptions to this general rule:

  • Puppies under 6 months may need baths more often, like once a week or every 2 weeks.
  • Dogs with short hair coats may only need bathing every 6-8 weeks.
  • Dogs with long hair coats may need baths more frequently, like every 3-4 weeks.
  • Dogs with skin allergies or skin conditions may need medicated baths as recommended by your vet.

Bathing any more frequently than every 3-4 weeks can dry out your dog’s sensitive skin, especially if you use dog shampoo each time. For most adult dogs, sticking to a bath every 1-2 months is sufficient to keep their coat and skin clean and healthy.

Factors That Impact Bathing Needs

Every dog is unique, so ideal bathing frequency will vary. Here are some factors that can impact how often your dog needs a bath:

Coat Type

Dogs with thick double coats, like Golden Retrievers and Siberian Huskies, may only need bathed every 6-12 weeks. Their dense fur protects their skin and repels dirt. But dogs with thin single coats, like Greyhounds and Boxers, will need more frequent baths since dirt penetrates down to their skin more easily.

Shedding Amount

Heavy shedders like German Shepherds and Labs tend to get dirtier faster. All that loose fur floating around sticks to natural skin oils. So dogs that shed a lot may need bathed a bit more frequently than light shedders.

Activity Level

The more time your dog spends running, hiking, swimming, and rolling around outside, the dirtier they will get. Very active dogs that spend most of their time outdoors typically need more baths than indoor lap dogs.

Skin Sensitivity

Dogs with sensitive skin or skin allergies may need their bathing schedule tailored to their specific needs. Some sensitive dogs do best with medicated baths while others need moisturizing shampoos. Check with your vet if your dog has irritated skin.

Coat Color

Dogs with light colored coats like white and yellow show dirt much easier than dogs with darker fur. So lighter colored pups tend to need baths more often to keep their coats looking clean.

Coat Type Bathing Frequency Recommendation
Short, thin coat Every 6-8 weeks
Long, thick double coat Every 8-12 weeks
Sheds heavily Every 4-6 weeks
Light colored coat Every 4-6 weeks
Sensitive skin As needed/vet recommended

Signs It’s Time for a Bath

The best way to tell if your dog is due for a bath is to check for any of these signs:

  • Greasy coat – If their fur looks slick or greasy, it’s bath time.
  • Dirt build-up – Check for grime around their eyes, mouth, legs, belly, and rear.
  • Matted fur – Excess oils and knots means they need washed.
  • Odor – If they have a foul doggy smell, a bath will refresh them.
  • Dandruff – Flaky skin or dandruff may indicate dry skin.
  • Itching – Frequent scratching or signs of irritated skin means a bath could help.

Even if it hasn’t been that long since their last bath, wash your dog as soon as you notice any of these issues for optimal coat and skin health.

How Long Between Baths is Too Long?

While an occasional longer stretch between baths won’t harm your dog, there is such a thing as too long between washing. Here are some guidelines on when bathing frequency has become insufficient:

8-12 weeks between baths

For most adult dogs with typical activity levels and coat types, any longer than 2-3 months between baths is too long. An every 8-12 week bathing schedule is ideal for maintaining clean fur and skin.

When they become visibly dirty

Once your dog is visibly dirty with greasy fur, caked on mud, foul odors, or skin irritation, they are overdue for a bath. Don’t wait for their usual bathing date if you can tell they need one sooner.

When you can smell them

If your dog has a noticeable “doggy odor” even when they aren’t wet, that’s a sure sign it’s been too long since their last bath. A clean dog should not smell strongly.

If their skin becomes irritated

Letting too much time pass between baths can lead to skin irritation and discomfort for your dog. Signs like frequent scratching, dry flaky skin, redness, and skin infections all indicate it’s time to bathe them.

When their coat seems dull

Over time, dirt, dander, and excess oil will build up on your dog’s coat. This causes it to look dull, matted, and greasy. A bath restores shine and luster to the coat.

Special Considerations

While most adult dogs do well with bathing every 1-3 months, some special factors may require more or less frequent bathing schedules:


Puppies under 6 months usually need bathed weekly or every 2 weeks. Their immature skin produces more oil which leads to a quicker build-up of grime. Frequent puppy baths prevent skin issues.

Elderly dogs

Older dogs with sensitivity or mobility issues may only need bathed every 2-3 months. Check with your vet on an appropriate senior dog bathing routine.


Dogs that swim regularly may need occasional extra baths to remove chlorine, lake water, or ocean salt that can dry out their skin and coat.


Dogs with diagnosed skin allergies or conditions often need medicated baths as frequently as prescribed by their veterinarian.

Fleas or skin infections

If your dog has fleas or a bacterial skin infection like pyoderma, they will need medicated baths more often until the issue resolves.

Dry, sensitive skin

Some dogs are naturally prone to dry, sensitive skin. For these dogs, less frequent baths plus moisturizing shampoos are best.

Tips for Bathing Your Dog at Home

Follow these tips for an easy, effective at-home bathing session for your dog:

  • Brush their coat thoroughly before bathing to remove loose hair.
  • Fill your tub with a few inches of lukewarm water.
  • Use a cup to wet their coat rather than a detachable sprayer head.
  • Use a mild dog shampoo and lather up well.
  • Avoid getting water and soap in their eyes and ears.
  • Rinse very thoroughly until the water runs clear.
  • Towel dry, then use a blow dryer on a low heat setting.
  • Brush their coat after drying to distribute natural oils.
  • Trim toenails and clean ears after bathing.

With the right shampoo and some practice, bathing your dog at home can be easy and rewarding. Getting on the right bathing schedule will keep them clean, healthy, and looking their very best.


Most adult dogs only need baths every 4-6 weeks. However, factors like coat type, shedding amount, activity level, and skin sensitivity can impact how often your dog needs to be bathed. While occasional longer stretches between baths are fine, be sure to wash your dog as soon as they appear visibly dirty or smelly. Following basic bathing tips and getting on an optimal bathing routine will keep your furry best friend clean, fresh, and healthy.
