Summer Skin: Hot Spots, Itching & Allergy Care (2026 Guide)

Published July 2026 · ~7 min read

If your pet spends the summer scratching, licking their paws or shaking their head, you’re not imagining it — summer is peak itch season. Pollen and grasses are at their height, heat and moisture create the perfect conditions for skin trouble, fleas are active, and swimming leaves coats damp. Often several of these stack up at once. Here’s how to sort out what’s going on and help your pet feel comfortable in their own skin again.

Why summer is itch season

The same things that make summer great for us are hard on pet skin: airborne pollen and grass, warm damp weather that lets bacteria and yeast thrive, more time outdoors in contact with allergens, and peak flea activity. A pet with borderline skin all year can tip into a full flare in July.

Seasonal (environmental) allergies

Environmental allergies — to pollen, grasses, moulds and dust — are one of the most common reasons pets itch in summer. In pets, the sign is usually itchy skin rather than a runny nose: watch for licking and chewing at the paws, face rubbing, recurring ear infections, and red or irritated skin in the armpits and belly.

A few things genuinely help. Wipe your pet down with a damp cloth after walks to lift pollen off the coat, keep up with flea prevention so it isn’t adding to the load, and support the skin barrier from the inside with omega-3 fatty acids. For persistent or severe itching, your vet has effective medications — seasonal allergies are very manageable once you have a plan.

Hot spots: the summer classic

A hot spot (acute moist dermatitis) is a red, raw, often oozing patch that can appear and spread in hours. Summer is prime time because they thrive where the skin stays warm and damp — under a thick coat, after swimming, or anywhere a pet has been licking. Once one starts, the itch-lick-worsen cycle makes it grow fast.

If you catch a small one: trim the fur around it so air can reach it, clean it gently, and keep it dry — and stop the licking, because licking is what keeps it going. Larger, painful or spreading hot spots need a vet, who can treat the infection and break the cycle properly. A soothing medicated shampoo such as TropiClean OxyMed Oatmeal Shampoo or Vet’s Best Oatmeal Medicated Shampoo can help calm irritated skin as part of a care plan.

Bathing right

The right bath soothes; the wrong routine makes things worse. Use a gentle, soothing shampoo — colloidal oatmeal and aloe are the classics for irritated skin, like TropiClean Aloe & Coconut — and rinse thoroughly, since leftover residue itches. Don’t over-bathe, which strips the natural oils that protect the skin; for most itchy pets a soothing bath every week or two during a flare is plenty, unless your vet advises otherwise.

Feeding for healthier skin

Skin health starts in the bowl. Omega-3 fatty acids (from fish oil and similar sources) support the skin barrier and help calm inflammation, and a salmon oil supplement is an easy add-on to most diets. If your pet has ongoing skin trouble, a food built for skin and coat — or a limited-ingredient diet if a food sensitivity is suspected — can make a real difference. Browse our skin and coat food and limited-ingredient options, and always change foods gradually over 7–10 days.

Grooming and coat care

Regular brushing removes the dead undercoat that traps heat and moisture against the skin — exactly what hot spots love. But resist the urge to shave a double-coated breed: that coat actually insulates against heat and protects against sunburn, and shaving it can do more harm than good. Our shedding season grooming tools help you manage the coat without taking it off. Keep floppy ears dry after swims, and check between the toes, a favourite spot for irritation.

When to see the vet

Home care handles mild, occasional itching. See your vet if the itching is constant or disrupting sleep, if you find raw or infected-looking skin, if there are recurring ear infections, or if there’s hair loss or a bad smell. These point to an infection or an allergy that needs proper treatment — and modern options work well once you have a diagnosis.

The bottom line

Summer throws pollen, heat, moisture and fleas at your pet’s skin all at once. Wipe off allergens after walks, stay on flea prevention, bathe with a soothing shampoo without overdoing it, support the skin with omega-3s and the right food, and don’t shave the double coats. When itching turns constant or the skin breaks down, your vet can get ahead of it quickly.
