Can I Give My Dog Allegra?

Can I give my dog Allegra?Skin irritations, runny eyes, and sneezing are some signs that may indicate an allergy, and you might be considering Allegra for your dog. When we are exposed to allergens that are common in the environment we are in, some of us who are hypersensitive to those common allergens develop allergic symptoms such as those previously mentioned.

In the same way, dogs have certain allergies, too, and it is fairly easy to identify when they are having an allergic reaction because of the obvious symptoms of wheezing, itchy eyes, stuffy nose, and even skin reactions. While humans rely on antihistamines to reduce the effects of allergy in their bodies, is it also safe to give dogs an antihistamine such as Allegra?

Allegra is a popular brand name of Fexofenadine or Fexofenadina in Spanish. It is an antihistamine known for effectively reducing the effects of histamine, including itching, watery eyes, and sneezing due to certain allergens. Although allergens are mostly harmless substances in our surroundings, dogs with allergies are affected in many ways when they inhale or ingest these allergens.

Can I Give My Dog Allegra? Answer: Yes

Some of the most common allergens in dogs are dander, mold spores, dust, feathers, cigarette smoke, some food ingredients, and prescription drugs. If you see your dog manifesting these symptoms: red and itchy skin, watery eyes, increased scratching, sneezing, vomiting, diarrhea, and constant licking, they are most probably showing signs of allergies.

Taking your dog to the vet is the first thing to do when allergic reactions arise. Your vet will most probably conduct a thorough examination of your dog to identify what is causing the allergy. This then will lead to knowing the best treatment for them. A standard medication that vets give to dogs suffering from an allergic reaction is an antihistamine such as Allegra. The antihistamine works to block the effects of a substance or chemical that triggers the allergy symptoms.

Dog allergies are not uncommon. Seeing your dog suffer from the symptoms of certain allergies is quite bothersome because we know that itchy eyes, runny nose, constant sneezing, and skin irritations can bring so much discomfort. Dog allergies come in different types, based on what causes the allergy. It can be external allergies, food allergies, and/or environmental allergies. This is why taking them to the vet for a thorough check-up will help you identify what your dog is allergic to and how you can best treat your dog.

To reduce the effects of the symptoms, vets usually prescribe over-the-counter antihistamines like Benadryl, Claritin, and Allegra. Allegra has been given to dogs with allergy, and has been proven safe and effective as long as it is given for the right purpose and within the correct dosage.

According to, the use of Allegra in dogs showed, “no evidence of toxicity was observed at oral doses up to 2 mg/kg.”

Other Side Effects of Allegra in Dogs

Among all antihistamines in the market that are prescribed to dogs with allergies, Allegra is considered to have the fewest side effects. Your dog might experience mild stomach upsets and dizziness, but this is rare when given medication under proper administration. If your dog manifests severe side effects after taking Allegra such as coughing and vomiting, contact your vet right away.

K9 Allergies & Your Environment

When your dog has an allergy, it might be a sign for you to accomplish some tasks for your home. Make a strong effort to clean your home by sweeping and mopping the floors, and vacuuming rugs and furniture. Pet dander can reach every part of your home and so try to eliminate them to the best of your ability. Try getting an air purifier with a HEPA filter to help catch the allergens that cannot be eliminated with simple cleaning.

Home Remedies for Dog Allergy

Skin irritations will definitely cause a lot of itching and scratching. Get rid of that by mixing baking soda in cool water, and pour it on the itchy parts. Try bathing your dog in oatmeal dissolved in cool water for about ten minutes to also lessen the itching. Mineral oil might also help in reducing the itchiness in a certain area. Just pour it on a cotton ball and swab it in and around the area.

I’m a bit worried about Piriton, half per day due to drowsiness. Looking at Allegra?

You seem to not have complete information on colostrum and, therefore, you should take a moment and review information on a site such as Web MD. All female mammals produce colostrum around the time of birthing, and that includes humans. The production of colostrum does not continue, but rather is the first milk that is produced.

It’s true that antibodies are passed through breast milk (which is why mothers are encouraged to breast feed,) but in all probability they are species/breed specific. So it doesn’t seem logical that cow’s colostrum would benefit a dog. I have never seen it commercially available. I don’t know where you acquired this information, but I don’t think it’s plausible. You may think of it this way: for humans with allergies, allergy shots are often recommended. The person is first tested for specific allergies, and then a shot is prepared from the specific antigen.

Over time an immunity is built up to the offending allergen (antigen). Building up an immunity to a specific antigen results in the production of specific antibody – often referred to as the lock-key relationship.

I have been reading up on Colostrum (from a cow) and it seems that animals have reacted very well to it, that it helps alleviate allergies. Has anyone tried this before? Thanks
