Summer Skin Troubles in Dogs: Causes, Treatments & Prevention Tips

When summer arrives, we all enjoy the sunshine and longer days. However, for our furry friends, the humidity and heat can lead to a range of skin issues. Dogs are more prone to skin problems during the warmer months due to increased exposure to allergens, parasites, and moisture. As a pet parent, it’s essential to recognize the signs early and know how to treat and prevent these problems to keep your dog happy and healthy throughout the entire season.

1. Hot Spots (Acute Moist Dermatitis)

What Are They?

Hot spots are red, inflamed, and often oozing patches of skin that appear suddenly and spread quickly. They are caused by excessive licking, scratching, or chewing, often due to allergies, insect bites, or underlying infections.

Symptoms:

  • Red, moist, and irritated skin
  • Hair loss in affected areas
  • Constant licking or scratching

Treatment:

  • Trim the hair around the area to let it breathe
  • Gently clean the wound with antiseptic solutions
  • Apply vet-approved topical creams
  • Use an Elizabethan collar to prevent licking
  • Visit your vet if the hot spot worsens or spreads

Prevention:

  • Keep your dog’s coat dry and clean
  • Address flea or tick infestations early
  • Treat allergies with the help of your vet

2. Flea Allergy Dermatitis

What Is It?

Flea bites can cause allergic reactions in some dogs, leading to intense itching, inflammation, and skin infections. Just one flea bite can trigger a severe reaction in sensitive dogs.

Symptoms:

  • Itchy, red bumps, especially around the tail, belly, and groin
  • Scabs or crusty skin
  • Hair loss in specific areas

Treatment:

  • Administer flea treatment recommended by your vet
  • Clean and vacuum your home thoroughly
  • Use flea shampoos, sprays, or collars

Prevention:

  • Regular flea and tick prevention year-round
  • Keep your pet’s bedding and environment clean
  • Use vet-approved flea treatments monthly

3. Sunburn

Yes, Dogs Can Get Sunburn Too!

Light-colored, short-haired, and hairless dogs are more prone to sunburn. Overexposure can lead to painful burns and even increase the risk of skin cancer.

Symptoms:

  • Red, dry, or flaking skin
  • Sensitivity to touch
  • Peeling or blistering in severe cases

Treatment:

  • Apply pet-safe soothing ointments like aloe vera
  • Keep your dog in the shade
  • Consult a vet for severe burns

Prevention:

  • Limit sun exposure, especially between 10 AM and 4 PM
  • Use pet-safe sunscreen on exposed areas
  • Dress your dog in lightweight protective clothing if needed

4. Yeast Infections

What Are They?

Yeast thrives in warm, moist environments. Dogs with skin folds, such as Pugs and Bulldogs, are especially at risk in summer.

Symptoms:

  • Musty odor
  • Greasy, discolored skin
  • Constant itching and licking
  • Crusty or scaly patches

Treatment:

  • Medicated shampoos and topical antifungal creams
  • Oral antifungal medication (in severe cases)
  • Keep affected areas dry and clean

Prevention:

  • Regular bathing with vet-recommended products
  • Dry your dog thoroughly after swimming or bathing
  • Clean skin folds regularly

5. Swimmer’s Itch (Skin Irritation from Water)

What Is It?

Prolonged exposure to lakes, pools, or sprinklers can cause skin irritation in dogs. Chlorine and bacteria in the water can lead to itchiness or infections.

Symptoms:

  • Itching or rashes after water activities
  • Dry or flaky skin
  • Licking or chewing affected areas

Treatment:

  • After your dog goes for a swim, be sure to rinse them off with fresh, clean water to remove any chlorine, salt, or debris.
  • Use hypoallergenic dog shampoos
  • Apply vet-approved anti-itch sprays or lotions

Prevention:

  • Dry your dog thoroughly after water play
  • Avoid stagnant or dirty water sources
  • Maintain a clean and well-groomed coat

6. Allergic Reactions

What Causes Them?

Summer brings pollen, mold, grass, and insect bites—common triggers for allergies in dogs.

Symptoms:

  • Red, itchy skin
  • Frequent ear infections
  • Watery eyes or sneezing
  • Excessive licking of paws

Treatment:

  • Identify and avoid allergens if possible
  • Allergy medications or antihistamines prescribed by a vet
  • Regular cleaning of your dog’s bedding and paws

Prevention:

  • Rinse your dog’s feet after walks
  • Use air purifiers at home

Speak with your veterinarian about conducting allergy tests and exploring suitable treatment plans.

When to See a Vet

Not all skin issues can be managed at home. Visit your vet if:

  • Symptoms persist for more than a few days
  • Your dog is in visible discomfort
  • You notice signs of infection like odor, pus, or swelling

Final Thoughts

The summer heat can be harsh on your dog’s skin, but with the proper care and early prevention, you can help keep skin issues at bay all season long. Regular grooming, flea prevention, staying dry, and avoiding sun exposure are key. Monitor your dog closely for any changes in their skin, and don’t hesitate to consult your veterinarian if you notice anything unusual.

Keeping your dog comfortable and itch-free this summer will ensure they enjoy the season just as much as you do!

Two sweet girlies decided to make our deck their home. Mosquitoes are a big problem where we live and we had to get them protected. This was the best bang for the buck. I’ve ordered from 79Pets several times and while delivery is not fast it is very consistent.

After Seresto collars failed to get rid of fleas, I didn't know where to turn. I saw a post on a page I follow (Kentucky Kitty Cats) saying that they use Nexgard Combo for the cats they shelter. I decided to try it and IT WORKS!

Customer photo review of Revolution Plus For Medium Cats 5.6-11 lbs (2.6-5kg)

Last year, I made a visit to the vet. I told them that Kattie/cat had ear mites. They gave me an ointment costing $80canadian. I used it up and purchased another bottle. $160. total not including the cost of the vet visit. No results. The ear mites have been there for a long time. Canadian vets have control of what is sold in Pet stores and you cannot purchase off the shelf products not recognized by them. I jumped at the chance to purchase your produce with a recommended 100% effectivity. I was willing to try, but was suspicions. After a month there was still a little scratching but after 6 weeks, the mites are gone and the scratching is gone. Thank you very much for this mite solution. I recommend it heartily. Harry P.S. Do not tell the Canadian vets as they will outlaw your product.
