Dog Skin Allergies: Causes, Symptoms, and Treatment

Our furry companions, dogs, often experience various health issues, with skin allergies being one of the most common. Just like humans, dogs can suffer from allergic reactions that can cause discomfort and distress. Understanding the causes, symptoms, and treatment options for dog skin allergies is crucial for pet owners to ensure their beloved pets live a happy and itch-free life.

What Do Skin Allergies Look Like on A Dog?

Skin allergies in dogs can manifest in various ways, and the appearance can vary depending on the specific type of allergy and the individual dog's reaction. Common signs of skin allergies in dogs include:

• Itching and Scratching

• Redness and Inflammation

• Hair Loss

• Hot Spots

• Rashes

• Ear Infections

• Paw Chewing

• Face Rubbing

• Thickened Skin

Can Dogs Have Seasonal Allergies?

Yes, dogs can have seasonal allergies, just like humans. Seasonal allergies in dogs are often referred to as "canine atopy" or "allergic dermatitis." These allergies are typically triggered by airborne allergens such as pollen, grasses, trees, and molds. When a dog with seasonal allergies comes into contact with these allergens, it can lead to allergic reactions.

Common signs of seasonal allergies in dogs include:

• Itching and scratching, especially around the face, paws, ears, and belly.

• Redness and inflammation of the skin.

• Excessive licking or chewing of paws.

• Watery eyes.

• Sneezing.

• Runny nose.

• Ear infections (due to increased moisture and inflammation in the ear canals).

Treating Seasonal Allergies in Dogs

If your Dogs has received a diagnosis of seasonal allergies, you have the option to explore remedies that can be administered at home:

• Administering oral antihistamines

• Using topically applied wipes and shampoos

• Incorporating Omega-3 fatty acids into their diet

• Providing them with probiotics

1. Oral Antihistamines

Antihistamines like Diphenhydramine, Chlorpheniramine, and Claritin (loratadine) can help reduce itching, sneezing, and other allergy symptoms in dogs.

Chlorpheniramine Dosage for Dogs

• For small dogs (under 20 pounds or approximately 9 kilograms): 2-4 mg every 8-12 hours.

• For medium-sized dogs (20-50 pounds or approximately 9-23 kilograms): 4-8 mg every 8-12 hours.

• For large dogs (over 50 pounds or approximately 23 kilograms): 8-12 mg every 8-12 hours.

2. Topically Applied Wipes and Shampoos

Hypoallergenic or medicated shampoos and wipes can help soothe your dog's itchy skin and remove allergens from its coat.
Be sure to choose products recommended by your vet and follow their instructions for use.

You could also try using a spray designed to reduce itching such as Puainta Anti-itch spray.
Veterinary shampoos and conditioners, like Puainta® Sensitive Skin Shampoo, are also formulated to quickly reduce itching and dryness.

3. Incorporating Omega-3 Fatty Acids

 Omega-3s have the potential to regulate the immune response and alleviate the inflammatory reactions that contribute to allergy symptoms.

It's essential to understand that while omega-3 fatty acids may offer certain advantages, they should not be viewed as a sole treatment for seasonal allergies in cats. In some instances, a multifaceted approach may be advisable, including antihistamines, topical treatments, hypoallergenic diets, and potentially omega-3 supplements.

4. Providing Probiotics

Probiotics can help support your dog's gut health, which may indirectly improve their immune system and reduce allergic reactions.
Ask your vet for recommendations on suitable probiotic supplements for your dog.

What Other Causes of Skin Allergies in Dogs?

Skin allergies in dogs can be caused by various factors, including:

1. Fleas and Insect Bites

Flea allergies are one of the most common causes of skin allergies in dogs. Some dogs are hypersensitive to flea bites, and even a single bite can trigger intense itching and skin irritation. Besides fleas, other insects like mosquitoes, ticks, and mites can bite dogs and cause allergic reactions, leading to itching and skin irritation.

Treatments for Flea Allergy Dermatitis

• The first step is to eliminate the source of the problem: fleas. Use flea control products recommended by your veterinarian. This may include topical treatments, oral medications, or collars.
  Regularly vacuum your home, wash your dog's bedding, and clean their environment to remove flea eggs, larvae, and pupae.

• Consider using flea preventive measures year-round to keep your dog protected.

• Frequent grooming and brushing can help you detect and remove fleas and ticks early before they can cause an allergic reaction.

In cases of severe allergies, your veterinarian may recommend ASIT, a treatment that involves injecting your dog with small amounts of the allergen (in this case, flea saliva) to desensitize their immune system.

Flea repellents for dogs can come in various forms, including topical treatments, collars, shampoos, and sprays. The active ingredients in these products can vary, but some common ones include:

• Fipronil: Fipronil is a commonly used active ingredient in many topical flea treatments for dogs. It works by disrupting the nervous system of fleas and ticks.

• Imidacloprid: Imidacloprid is often used in conjunction with other ingredients in topical flea treatments. It also affects the nervous system of fleas and other insects.

• Selamectin: Selamectin is found in some topical flea and tick treatments. It not only repels fleas and ticks but also has a broad-spectrum effect against other parasites like heartworms and mites.

• Nitenpyram: Nitenpyram is an oral flea treatment that is typically administered as a tablet. It quickly kills adult fleas on the dog but doesn't have a long-lasting repellent effect.

2. Food Allergies

Dogs can develop allergies to certain ingredients in their food, such as proteins (e.g., chicken, beef), grains (e.g., wheat, corn), or additives. Food allergies can lead to skin problems, including itching, redness, and inflammation.

Treatments for Food Allergies

The first step in treating a food allergy is to identify the specific ingredient or ingredients that trigger the allergic reaction. This is typically done through an elimination diet or food trial under the guidance of a veterinarian.

Once the allergen has been identified, it's essential to eliminate it from your dog's diet entirely. This may involve reading ingredient labels carefully and avoiding any treats or table scraps that contain the allergen.

Your veterinarian may recommend an elimination diet, which involves feeding your dog a novel protein and carbohydrate source that they have never been exposed to before. Common novel protein sources include venison, duck, or kangaroo, and novel carbohydrate sources may include sweet potatoes or peas. This diet should be strictly followed for several weeks to see if the allergic symptoms improve.

3. Environmental Allergens

Just like humans, dogs can be allergic to environmental allergens such as pollen, grass, mold, dust mites, and certain plants. This condition is known as atopic dermatitis or environmental allergies.

Treatments for Environmental Allergens

Treating dog allergies caused by environmental allergens can be challenging, but there are several approaches you can take to help manage your dog's symptoms and improve their quality of life. 

The most effective way to manage allergies is to reduce your dog's exposure to the allergens. Some steps you can take include:

• Keep your home clean by regularly vacuuming, dusting, and washing your dog's bedding.

• Use allergen-proof covers for your dog's bed and pillows.

• Consider using air purifiers with HEPA filters in your home.

• Keep your dog indoors during high pollen seasons or on windy days when allergen levels are high.

• Bathing your dog with a hypoallergenic shampoo can help remove allergens from their fur.

Allergy Testing and Immunotherapy:

Allergy testing, such as intradermal skin testing or blood tests, can help identify specific allergens triggering your dog's allergies. Once identified, your vet may recommend immunotherapy, which involves regular allergy shots or sublingual drops to desensitize your dog to the allergens over time.

What Dog Breeds Are Prone to Dog Skin Allergies:?

Atopic dermatitis is a genetic condition with certain breeds, such as those below.

• Terriers

• Beagles

• Irish and English Setters

• Lhasa Apsos

• Pugs

• English and French Bulldogs

• Miniature Schnauzer

• Labradors

• Golden Retrievers

• Labradoodles and Goldendoodles
