Understanding Hot Spots and How Grooming Helps

A hot spot can seem to appear overnight: one day your dog’s coat looks normal, the next there’s a raw, damp patch they won’t leave alone. Hot spots need a veterinarian, not a groomer, to diagnose and treat. But grooming habits do affect how much moisture and matting sits against your dog’s skin—and that’s the part this guide covers.

What a Hot Spot Looks Like

You don’t need to identify a hot spot for certain—that’s your vet’s job. What owners typically notice is:

• A red, moist, or oozing patch of skin, sometimes with matted or missing hair around it
• A spot your dog keeps licking, chewing, or scratching
• An area that seems painful—your dog flinches, pulls away, or gets upset when you go near it
• A patch that gets bigger quickly, sometimes over a day or two
• Damp, clumped hair or a crusty edge, sometimes with an odor

These patches often turn up under thick coats—on the neck, hips, or under the ears—where it’s hard to see the skin without parting the fur.

Why Damp Undercoat and Mats Matter

Dense coats hold water. When a thick or double coat isn’t dried all the way down to the skin after a bath, a swim, or a rainy walk, the undercoat can stay damp for hours. Mats add to the problem: matted hair can tighten and tug at the skin, and it holds moisture and debris right against it, where you can’t see what’s happening underneath. Moisture plus friction—from collars, harnesses, or packed undercoat—is exactly the combination worth keeping an eye on. For more, see why matted fur is more than a cosmetic problem.

Grooming Habits That Reduce Moisture

No grooming routine can promise a dog will never get a hot spot. These habits simply help keep the coat drier and easier to check:

• Dry completely. Especially for double coats and dense curls. Towel-blot, then use a dryer on a low, comfortable setting while brushing in sections, until the coat is dry to the skin—not just on the surface. Our post on why proper drying matters goes deeper.
• Mind the moisture. After rain, swimming, or snow, dry thoroughly and do a quick brush-through.
• Brush to the skin. Work in small sections and finish with a metal comb; if the comb snags, there’s still a tangle. Pay extra attention to friction zones: behind the ears, under collars or harnesses, armpits, tail base, and behind the knees.
• Mind the gear. Remove collars and harnesses indoors when safe, and let wet ones dry before putting them back on; moisture plus friction invites mats.
• Keep heavy undercoat thinned out. For double-coated dogs and heavy shedders, regular undercoat removal helps air reach the skin and helps the coat dry faster.
• Look while you brush. Part the coat as you go. Brushing sessions are the easiest time to notice a damp, red, or tender area early.

Where De-Shedding Fits

For thick-coated breeds, much of the challenge is volume: packed undercoat that traps water and takes a long time to dry. At Dapper Doodle Grooming, a de-shedding treatment is an add-on to a professional bath or full groom, starting at $30 depending on your dog’s size and coat. It pulls out loose undercoat, and every bath finishes with a blow-dry and brush-out. Most heavy shedders do well with de-shedding every 4–8 weeks, plus an extra visit when the coat blows in spring and fall. Shaving isn’t a shortcut here—see why shaving a double coat can do more harm than good.

If You Find One: Call Your Vet

If you spot a raw, moist, or painful patch:

• Don’t groom over it at home. Skip brushing, clipping, or bathing that area—it’s likely tender, and home grooming can make it more uncomfortable.
• Skip home remedies and human products.
• Call your veterinarian and describe what you see: where it is, how big it is, how fast it appeared, and whether your dog is licking or chewing it.
• Let your groomer know if you have an appointment coming up, so you can talk through timing together.

If we notice a sore or irritated patch during a groom, we’ll point it out at pickup so you can follow up with your vet. Grooming works alongside veterinary care, never instead of it. For other things groomers commonly spot, see common dog skin issues groomers notice first.

The Takeaway

Hot spots are a vet matter. What you can control is the coat: dry it fully, brush it to the skin, keep mats and heavy undercoat from building up, and check under the fur while you brush.
