Can My Chihuahua get hayfever?

What are hay fever symptoms in dogs?

In some ways, hayfever symptoms in dogs show in a similar way to humans with watery eyes, running noses and lots of sneezing, not pleasant for summertime walkies! And similarly to humans, sometimes dogs that suffer with hayfever seem to much prefer sitting indoors in the summer where there is air conditioning.

There is a difference in hayfever between people and dogs though, is the placement of allergy receptors and your chihuahua could experience some unique canine hayfever symptoms.

As the allergy receptors in dogs are on the skin, whereas human receptors are in the nose and eyes, you may notice your chihuahua suffer hayfever symptoms such as:

  • Oily coat
  • Flaky skin
  • Excessive itching, commonly on the ears, rectal area, and under the legs
  • Rubbing the face into the carpet
  • Rashes on the face and feet
  • Loss of hair around the eyes and feet
  • Reverse sneezing

Just like humans, dogs can experience hayfever at any time in their life and are not necessarily born with it. Most commonly dogs will start to suffer from hayfever when they are between one and three-years-old. However, this does not mean they will suffer from the allergy forever.

How to reduce hayfever symptoms in dogs

Choose low allergy walks

Again like humans, your chihuahua’s hayfever may be attributed to a particular type of pollen whether its tree, grass, weeds or flowering plants. For mild hayfever symptoms, you may notice specific walks give your pup a higher level of allergy and can work out what areas and plant life you need to avoid. Keep a record of the environment of the walk and your chi’s symptoms, and you may be able to protect your dog and still enjoy those summertime walks.

Boost your dog’s immune system

Surprisingly, you can reduce the symptoms of allergies through optimum health. While it will take a level of trial and error to find out what your dog needs to be at optimum health, you can try an array of superfoods such as spirulina and barley grass, both of which are rich in skin-health vitamins and minerals.

Boost Omega levels with flax seed or hemp seed oil can also help to give skin fighting power. Make sure your pup’s food is full of nutrition and packed with vitamins so your chi can have reduced allergic reactions. You can build up your chihuahua with a nutritious bone broth and keep it in the freezer.

I add this supplement into our dogs food, it supports the gut (and helps with calmness) which is where most allergies start. It’s now available as senior supplement as well.

Remove pollen quickly

After every walk wipe your chi’s feet and face with a damp cloth. This will help to eliminate any pollen they may have picked up on the walk and will reduce the amount of pollen entering the home.

Keep your home pollen-free by vacuuming regularly and washing your dog’s bed and towels often to keep airborne pollen particles away from your pet and any allergy sufferers in your home. If your chihuahua suffers badly from hayfever, then it may be wise to keep windows shut and to use air-conditioning to filter out the pollen. Take a look at the services that offer air conditioning in Carrolton, or wherever you are based, to keep your indoor air as clean and pollen-free as possible.

It may also be a good idea to try and keep other allergy triggers down to a minimum. It might not just be hay fever that is causing the allergies. Some common household cleaners can also cause you chihuahua problems.

Once your chihuahua starts sneezing and having watery eyes you may notice tear staining, this can be annoying and difficult to remove. Tear staining is when the bacteria on your dogs coat reacts with the tears and cases a rust like staining. A gentle wipe with colloidal silver may help. We use this a lot on tear stains and sore spots.


You can give your chihuahua some OTC medications. Ordinary antihistamines are OK for your dog. Give your chihuahua a quarter or half a tablet daily to help reduce symptoms. They will be much cheaper than buying them from the vet. (if you are not sure then call the vet and ask.)

In very bad cases, your vet may even suggest steroid injections to keep allergy responses at bay. If you think your chi has an allergy, consult your vet and find out the best ways to help your pet through medication and at home.
