What Are the Most Common Allergies in Dogs?


Where humans are concerned, sneezing, watery eyes, wheezing, and coughing are the most common symptoms of allergies. But dog allergies primarily affect their skin, making your pooch extremely itchy and eager to scratch – even to the point of opening wounds on their skin. Dog allergies vary, but the most common ones can be classified into three groups:


  • Environmental: Pollen, mold, dust, grass, smoke, weeds, and fungi are the most common triggers. However, chemicals and perfumes are also known to trigger an allergic reaction in some dogs. Pooches with environmental allergies can experience symptoms seasonally or year-round.


  • Food: Dogs with food allergies can experience itching or gastrointestinal problems like vomiting or diarrhea. The most common food allergens are beef, dairy, wheat, eggs, chicken, lamb, soy, pork, rabbit, and fish. Dogs with food allergies are usually allergic to more than one thing. The most common symptoms of food allergies in dogs are itching, scabs, hot spots, and reoccurring ear infections.


  • Insect bites: Flea bites are the most common insects that bite dogs. Flea allergy dermatitis happens when a dog’s immune system reacts to proteins in flea saliva that end up deposited on the skin. Dogs that experience other types of allergies are more likely to develop flea allergy dermatitis.



What to Look for in Dog Supplements for Allergies


Many herbs and natural ingredients can relieve inflammation and itching caused by allergies, but not all are equally effective. Most quality supplements for dog allergies contain omega fatty acids, probiotics, quercetin, colostrum, and bromelain for their immune-boosting and histamine-reducing effects. Some formulas may also contain apple cider vinegar which relieves itchy skin and rashes; turmeric, which helps ease redness, swelling, and itching; biotin, a B-complex vitamin that promotes skin and coat health; and digestive enzymes that promote gut health and reduce swelling. Check the ingredients listed on the product label, and pick a supplement based on the severity of your pup’s allergies. When shopping for supplements for dog allergies, consider if it will be convenient to administer them to your dog. Supplements for dog allergies usually come in the form of soft chews, chewable tablets, or powder. If you have a picky eater, powder supplements might be easier to administer than chewable tablets. Your pooch will be none the wiser if you mix a flavorless powder supplement into their wet food, but you might have a hard time getting your dog to swallow a tablet.

As always, consult your veterinarian before including any supplement in your dog’s diet, even if it’s completely natural. This is especially true if your pooch is already on allergy medications. Your veterinarian knows your pooch and their medical history the best and can tell you if the ingredients in the supplement are safe for your pet to consume.
