Summary

  • Different allergy medications treat different types of allergies
    Your dog may suffer from environmental, food, or flea-based allergies, all requiring different treatments.
  • There are lots of treatment options available
    Dogs can get allergy relief from prescription and over-the-counter (OTC) medications, as well as home remedies and DIY alternatives.
  • Talk to your vet before giving your dog allergy meds
    A professional can give you the right dosage for your dog and warn you about potential drug interactions.

Sneezing, excessive scratching, and watery eyes are all signs that your beloved dog is dealing with allergies. While allergies are a fairly common condition in dogs, no one likes to see their best friend suffer. Several different medications offer allergy relief, but the best one for your dog depends on the cause of their allergies.

Medications for treating seasonal allergies in dogs

Many dogs experience seasonal allergies in the spring and summer with the surge in airborne irritants like grass, tree, and weed pollen. Other common allergens include environmental pollutants, chemical products like shampoos and perfumes, dust mites, mold, and mildew.

Managing seasonal allergies in dogs is very similar to managing them in people, and there are several techniques involved in managing allergies.

Springtime pollen can cause pups to experience allergy symptoms like itchy skin.

OTC medications

Mild to moderate cases of canine allergies can often be treated with the help of over-the-counter (OTC) medications. However, just because over-the-counter medications are easily accessible does not mean you can start giving them to your dog right away. Ask your vet about dog-friendly OTC options to learn more about proper dosing and potential interactions.

  • Antihistamines
    Popular human OTC allergy meds like Benadryl (diphenhydramine) and Zyrtec (cetirizine) can relieve allergy symptoms in dogs. The active ingredients in these drugs can also be found in itch and allergy supplements specifically formulated for dogs.
  • Wipes and shampoos
    Dogs with atopic dermatitis can get added allergy relief by using pet wipes and nourishing shampoos in conjunction with oral antihistamines. Wipe them down with allergy relief wipes when they’re done playing in the grass to get pollen, mold, and other potential allergens out of their fur.

DIY home remedies

Home remedies can make for handy, cost-effective ways to treat your dog’s allergies. Common household foods like oats, apple cider vinegar, and plain, sugar-free yogurt can provide quick relief for uncomfortable itching and inflammation. Other DIY solutions include

  • Essential fatty acids
    Clinical studies show that fish oil supplements can lessen the inflammation brought on by skin allergies and strengthen skin cells’ resistance to environmental allergens.
  • Probiotics
    Intestinal inflammation and abnormal gut bacteria can cause imbalances in a dog’s immune system that intensify the symptoms of allergies. Probiotic supplements introduce healthy bacteria that repair the gut and may help lessen the intensity of symptoms.
  • Quercetin
    This plant pigment is naturally present in several fruits, vegetables, and grains. Like an antihistamine, it inhibits the body’s production of inflammatory histamines brought on by seasonal allergies. Take the time to go over the ingredients on each product to avoid giving your dog toxic additives like xylitol.

Prescriptions from the vet

The vet is your first line of contact when you need to treat your cat’s UTI. If your vet sees it as necessary, they may prescribe antibiotics for the infection. They will likely prescribe an oral medication or an injectable medication. These antibiotics get rid of the infection or reduce inflammation.

There are supplements for urinary tract health, some of which carry glucosamine as an active ingredient. Prescription diets can also help. As for surgery, that will depend on whether the cause is bladder stones or frequent urinary obstruction.

Frequently asked questions

Is Benadryl or Zyrtec better for dogs?

Every dog is different, and their systems may react differently to certain allergy meds. Vets have recently noted more adverse reactions among dogs who take Benadryl, resulting in Zyrtec becoming the more popular “first-line” choice for dog allergies. Zyrtec is also less potent than Benadryl and has a convenient dosing schedule ranging from half to one full tablet a day, depending on your dog’s weigh.

Are there any potential side effects of allergy medicines for dogs?

Yes. Most allergy medications come with their own set of side effects but keep in mind that each dog is different and may experience unique side effects to allergy medications. Common reactions include dry mouth, lethargy, vomiting, diarrhea, increased heart and respiratory rates, hypersalivation, and decreased globulin levels.

What is the best allergy medicine for dog allergies?

The best allergy medication for your canine is the one your veterinarian recommends for their specific allergies. Many veterinarians will recommend an antihistamine to treat their symptoms.

Is there a daily allergy pill for dogs?

Yes, Zyrtec and Claritin can be given to dogs once a day; Benadryl is given twice a day. It’s always a good idea to check with your vet about the appropriate dosage for your dog’s size and age.

What do vets prescribe for dog allergies?

What your veterinarian prescribes for dog allergies depends on their severity. For mild itching, vets may prescribe antihistamines. For severe allergies, vets may do allergy testing so they can do immunotherapy  to boost your dog’s immune system.

“This way, reactions to allergens are much less intense. Immunotherapy is the closest that anyone can get to a “cure” for allergies,” says Dr. Erica Irish. “Intense itching can be helped with Apoquel, Cytopoint, or steroid medications. In other cases, immunosuppressant medications like Atopica may be necessary.”
