Why Your Dog's Mats Get Worse After a Bath (7 Fixes)

You give your dog a nice bath, hoping to clean up a few knots. Then the coat dries and the knots are bigger, harder and closer to the skin than before. It feels like the bath made things worse. In a way, it did.

We started Freshly Bailey in 2020 because keeping our doodle Bailey's coat healthy and free of mats was a real struggle, and bath day was a big part of that learning curve. The good news is that a few small changes to your bath routine can stop this from happening again.

Why do my dog's mats get worse after a bath?

A mat is loose hair and live hair twisted together into a knot. Water does not loosen that knot. It usually does the opposite.

1. Water tightens mats. When tangled hair gets wet, it swells and clumps together. As it dries, it shrinks and pulls the knot even tighter, often right down to the skin.
2. The tangles were there before the bath. Small tangles you could not see or feel turn into real mats once the coat is soaked. Bathing a coat that was not brushed out first is the most common cause.
3. Rubbing with a towel. Scrubbing the coat back and forth with a towel twists wet hair into new knots. The American Kennel Club says vigorous towel rubbing can cause tangles and mats, and suggests pressing the towel into the fur instead.
4. Slow air drying. A thick or curly coat can stay damp for hours. Damp hair that dries without being brushed tends to clump and felt, especially on the belly, legs and behind the ears.
5. Rolling and shaking after the bath. Most dogs love a post-bath zoomie, rolling on the carpet or rubbing on the couch. All that friction on a wet coat creates fresh tangles fast.

7 ways to stop mats from getting worse after a bath

1. Brush and comb out the coat before every bath

This is the big one. Never bathe a matted coat before you brush out the mats, because water makes mats tighter. Give the whole coat a full brush and comb before you turn on the water. If you can run a metal comb from the skin out everywhere, the coat is ready for a bath.

2. Mist with detangler spray before brushing

A light mist of detangling spray helps the brush glide instead of catch, so you pull less on your dog's skin. You can brush a damp coat or a dry one. Work the spray in with your fingers, then brush.

3. Brush in small sections, down to the skin

Brushing only the top of the coat leaves the knots underneath. Hold back a section of hair with one hand and brush the layer below it, a little at a time. This is called line brushing. A long pin slicker made for curly coats reaches the hair near the skin, where mats start.

4. Finish with a metal comb

A brush can make the coat look smooth while a knot hides underneath. After brushing, slide a metal comb through each area from the skin out. Start with the wide teeth, then switch to the narrow teeth. If the comb stops, go back with the brush. Check the spots that mat most: behind the ears, the armpits, the belly, the collar line and the back legs.

5. Use a conditioner in the bath

Shampoo cleans the coat. Conditioner helps it stay smooth and soft, so the hair is less likely to knot as it dries. Rinse very well, because leftover product can make hair sticky and clump together. Squeeze the water down the coat with your hands instead of scrubbing in circles.

6. Blot, do not rub, and dry fully

Press a towel into the coat to soak up water, then lift it and move to the next spot. A microfiber towel holds more water. If you use a dryer, choose one made for dogs on a cool or low setting, keep it away from the face and ears, and brush as you dry. The goal is a coat that is dry all the way to the skin, not just on top. Our post on why your doodle still smells after a bath has more drying tips.

7. Brush again once the coat is dry

When the coat is dry or nearly dry, give it one more quick brush and comb. This catches any small tangles from towel time or zoomies before they lock in. Keep your dog off the carpet and couch until then if you can, or lay down an old towel for rolling.

The tools we recommend for mats after a bath

A quick note: we make these tools, so we are biased. Here is why we recommend each one for mats that get worse after a bath.

Slicker Brush for Goldendoodles, Poodles & Doodles

The long, flexible pins reach down through thick, wavy and curly hair to the tangles near the skin, which is exactly what you need to clear before a bath. Choose the Small for dogs under 15 lbs and the Large for dogs 15 lbs and up. Use a light touch and let the pins do the work.

"WOW!! What a difference after using this doodle brush on my bernedoodle. Easier to brush and gets down to the skin without scratching."

Greyhound Metal Comb for Dogs

This is your "ready for the bath" test. The dual spacing lets you start with the wide teeth and finish with the narrow teeth, and it is made for doodle and poodle coats. If the comb glides from the skin out everywhere, there are no hidden knots for the water to tighten.

"The Freshly Bailey Metal Comb worked really well on my Goldendoodle’s coat. The dual teeth design makes it easy to work through both the thicker areas and the finer spots, and it helps remove tangles without pulling or irritating her skin."

Doodle Detangler Spray

A leave-in conditioner made for curly coats that works on damp or dry hair. Mist it on before your pre-bath brush-out, and again after the bath when you do your final brush. A light mist is plenty.

"Works great. Detangles the pups fur so it can be brushed without it hurting."

Review by Beth Weiland

Doodle Shampoo & Conditioner

Made with oatmeal and aloe for wavy and curly coats. The conditioner helps leave the hair soft and smooth, so it dries with fewer knots and is easier to brush and comb afterward.

"A little goes a long way and it left my doodles fur feeling nice and soft that is made the drying and combing process a lot easier. I recommend this product"

A simple mat-free bath day routine

1. Lightly mist the coat with detangler spray.
2. Brush the whole coat in small sections, down to the skin.
3. Run a metal comb through every area, wide teeth first, then narrow teeth. Fix any spot where it stops.
4. If you find a mat that is tight against the skin, skip the bath and book your groomer.
5. Bathe with shampoo, then conditioner. Rinse very well.
6. Squeeze out the water with your hands, then blot with a towel. Do not rub.
7. Dry the coat fully, brushing as you go if you use a dog dryer.
8. Once dry, give the coat one last brush and comb. Then praise and treat.

When to call your vet or groomer

Mats are more than a looks problem. PetMD notes that mats can pull on the skin, trap moisture and dirt, hide skin problems and cause pain. That is why a soaked, matted coat is a bigger worry than a dry one.

Ask your groomer for help if a mat is tight against the skin, covers a large area, or is near the eyes, ears or private areas. Do not cut mats out with scissors at home, because it is very easy to cut the skin. Call your vet if the skin under a mat looks red, raw, wet or broken, if there is a bad smell or discharge, or if your dog cries, snaps or pulls away when you touch the area. If your dog gets very stressed on bath day, a groomer who works with nervous dogs or a positive-reinforcement trainer can help. Our post on why your dog hates being brushed has more tips.

Frequently asked questions

Should I brush my dog before or after a bath?

Both. Brush and comb out every tangle before the bath so the water cannot tighten them. Then brush again once the coat is dry or nearly dry to catch any new tangles.

Will a bath loosen my dog's mats?

No. This is a common myth. Water makes mats swell and then shrink tighter as they dry. Always brush out mats first, then bathe.

Can I brush my dog while the coat is wet?

Yes. You can brush a wet or dry coat. Mist with detangler first, use a gentle touch, and work in small sections. Just make sure the mats are already out before the bath.

Is it okay to let my doodle air dry?

It is better not to. A thick or curly coat can stay damp for hours, and damp hair that is not brushed tends to clump into new mats. Blot with a towel and dry the coat fully, or at least brush it out once it is nearly dry.

How often should I bathe a dog that mats easily?

Most dogs only need a bath every few weeks. Bathing more often is fine if your dog's skin handles it, as long as you brush out the coat before each bath and dry it well after. Your groomer or vet can suggest a schedule for your dog's coat and skin.

If your dog's mats got worse after a bath, you did not do anything wrong. Most of us learn this one the hard way. Brush first, bathe second, blot and dry well, and bath day can leave your dog soft, clean and knot-free. For more on stopping doodle mats, see our post on why doodles mat so much during coat change.
