Dry, Itchy, Flaky Skin in Winter: What Actually Helps Dogs & Cats

Once the heat comes on, a lot of dogs and cats start scratching more. You might see white flakes on a dark coat, a dull, rough feel when you pet them, or a dog who suddenly cannot stop nibbling at their sides. One dog owner described it on Amazon: “she’s been itching and biting herself like crazy from the dryness of winter.”

This guide is about the skin and coat on the body: back, sides, belly and elbows. It covers a simple winter routine, the products owners reach for, and the signs that mean it is time for the vet instead of another bottle.

Short version: Add humidity at home, bathe less often with a gentle oatmeal shampoo, brush more, and ask your vet about an omega-3 supplement. Use sprays and balms on dry patches. Get any red, raw, smelly, scabby or bald area checked by your vet.

Why Skin Gets Drier in Winter

Cold outdoor air and indoor heating both pull moisture out of the air, and skin follows. Add more time curled up next to a heater, fewer outdoor rolls in the grass, and sometimes baths with harsh shampoo, and you get flakes and itch. Many winter skin complaints are just that: dry skin. But itching has a long list of causes, including fleas, allergies and skin infections, which is why the vet section below matters. If you find fleas on your dog, our guide to flea and tick prevention for dogs lines up the main options by weight.

A Simple Winter Skin Routine

1. Add humidity. A humidifier in the room where your pet sleeps helps everyone’s skin, yours included. Keep it out of reach and clean it as the maker directs.
2. Bathe less, and gently. Over-bathing strips natural oils. When your dog does need a bath, use a mild shampoo made for dogs, rinse very thoroughly, and dry them well.
3. Brush more often. Brushing lifts flakes and dead hair and spreads natural oils through the coat. Our at-home dog grooming tools guide covers which brush fits which coat.
4. Feed the skin from the inside. Ask your vet whether an omega-3 supplement makes sense for your pet, and keep fresh water available.
5. Treat dry patches directly. Use a dog-safe spray or balm on rough spots between baths.

The Picks, Up Close

Wahl Dry Skin & Itch Relief Pet Shampoo for Dogs, Oatmeal Formula, 24 oz

Wahl Oatmeal Shampoo — Check price on Amazon

An oatmeal-based dog shampoo that Wahl describes as pH balanced and free of alcohol and parabens, made for moisturizing dry skin and itch relief. It has a coconut lime verbena scent. Owners note that a little goes a long way and that it rinses clean. Rinse twice as long as you think you need to, because leftover shampoo is itchy too. This is a dog shampoo; do not use it on cats.

Best for: Dogs who need a bath and already have dry, flaky skin.

Zesty Paws Salmon Oil for Dogs & Cats, Omega-3, 8.5 oz

Zesty Paws Salmon Oil — Check price on Amazon

A pump bottle of wild Alaskan salmon oil that you add to food, labeled for both dogs and cats, with omega-3s EPA and DHA for skin and coat. Fish oil is one of the most common things vets suggest for dry skin. One cat owner wrote: “Salmon oil/omega 3 was recommended by the vet for my cat’s dry skin/dandruff.” Start with a small amount and build up to the label dose, since rich oils can upset some stomachs. If your pet has a medical condition or takes medication, ask your vet first.

Best for: Dogs and cats with a dull coat and flakes, as part of a vet-approved plan.

Palmer’s for Pets Cocoa Butter Dry Skin Relief Spray for Dogs, 8 fl oz

Palmer’s Dry Skin Relief Spray — Check price on Amazon

A cocoa butter and vitamin E spray for dogs that you mist onto dry, rough patches between baths. The maker describes it as non-greasy and notes that it is a grooming product, not a veterinary treatment. A spray is handy for dogs who do not like being rubbed with lotion.

Best for: Quick, low-fuss moisture for dry dogs between baths.

Natural Dog Company Skin Soother Dog Skin Balm

A twist-up balm stick for dogs with organic coconut oil, cocoa butter, safflower oil and vitamin E. You swipe it straight onto dry elbows, bellies and rough spots. It also contains lavender and myrrh, and some owners find the smell strong. The Amazon reviewer quoted at the top of this page said the smell is “extremely extremely strong” but that it was the only thing she tried that left her dog’s skin feeling moisturized. This one is made for dogs; keep it off cats.

Best for: Small dry, rough patches on dogs.

Pet MD Hydrocortisone Spray for Dogs, Cats & Horses

A 1% hydrocortisone spray labeled for dogs, cats and horses, without fragrance or dyes, for itching and redness from bites and other skin irritations. Ask your vet before using it. Hydrocortisone is a medicine, and itching can come from causes it will not fix. Your vet can tell you whether it suits your pet, where to use it and for how long. Do not use it on open wounds or near the eyes, and keep your pet from licking it off, which matters especially with cats.

Best for: Short-term use on itchy, irritated spots once your vet has said it is okay.

What About Cats?

Cats are trickier because they groom everything off their coat. A few rules make it simpler:

• Use cat-labeled products only. On this page, the salmon oil is labeled for cats, and the hydrocortisone spray is labeled for cats but should only be used if your vet says so. Do not use dog shampoos, sprays or balms on cats.
• Brush gently and often. Long-haired and older cats may struggle to groom well, and flakes build up along the back. Our cat deshedding brush guide covers gentle options.
• Watch the grooming. Bald patches or a cat who licks one area raw is a vet issue, not a dry-skin issue. See why cats overgroom.
• Keep water appealing. Fresh, clean water in several spots helps. If your cat barely drinks, see why your cat won’t drink water.

Dogs who lick more than usual may have more going on than dry skin; our guide to why a dog licks everything walks through the possibilities. If the itch comes with a lingering smell, why a dog still smells after a bath is the next read.

FAQ

How often should I bathe a dog with dry skin in winter?

Less often than you might think. Bathe when your dog is actually dirty or smelly, use a gentle shampoo made for dogs, and rinse thoroughly. Your vet or groomer can suggest a schedule for your dog’s coat type.

Can I use coconut oil or human lotion on my dog?

Dogs lick, and many human lotions contain fragrances and other ingredients not meant to be swallowed. Products made for pets are the safer choice. If you want to try something from your kitchen or bathroom, ask your vet first.

Is fish oil safe for cats?

Some fish oils, including the Zesty Paws salmon oil here, are labeled for cats. Follow the label dose for your cat’s weight, introduce it slowly, and ask your vet first if your cat has a health condition or takes medication.

Are winter flakes the same as dandruff?

Owners often use the words interchangeably. Light white flakes with no redness or odor are often dry skin. Thick, greasy or yellow flakes, or flakes that move, need a vet visit.

Final Take

Most winter itch gets better with a routine, not a single product: humidity at home, fewer and gentler baths with the Wahl oatmeal shampoo, more brushing, and an omega-3 like Zesty Paws salmon oil if your vet agrees. Keep the Palmer’s spray or the Skin Soother stick for dry patches on dogs, and only reach for hydrocortisone after you ask your vet. Anything red, raw, smelly or bald goes to the vet first. Do that, and most dogs and cats get through winter with softer coats and a lot less scratching.
