One of the most common symptoms reported by owners with dog allergies, red eyes is often an overlooked problem. Yet, it can be the initial sign to seek professional advice. This condition is also associated with other issues, such as glaucoma and conjunctivitis.

Frequent itching and irritation can often further aggravate many other symptoms, such as swelling, redness, and discharge. 


Healthy discharge from your dog’s eyes will be clear and watery. However, dog allergy eye discharge may appear colored or even milky.

What Causes Dog Eye Allergies?

Allergies can be caused by a whole range of factors, and as the symptoms overlap, it can be tricky to diagnose the root cause of your pup’s discomfort. Here are the most common reasons behind eye allergies in pups.


Food allergies result in an immune response, meaning that skin conditions such as swelling and itchiness are more likely to be present. Dietary sensitivities and intolerances can exacerbate itchiness and poor skin health. This can make dogs more susceptible to serious conditions, like skin infections and hair loss. 

Your vet will offer you advice on how to treat the trigger in your dog’s diet. And, help you create a healthier meal plan to limit the allergies and eye problems your furry friend is experiencing.

Environmental Factors

Environmental allergens such as dust, pollen, and even mold can create a reaction in your pup. If these come into contact with their eyes, it’s no wonder they become red and itchy. 

You may notice certain triggers are more frequent during specific seasons and times of the year. Take necessary steps to keep your pup well away from these. Consider the areas you take them on walks, and the times of day you choose to let them outside. 

If your dog comes into contact with the environmental triggers, wash them thoroughly and remove any traces. It’s easy for your pup to scratch their face or body and spread the allergens further — leading to more discomfort and issues.

Dog Eye Allergy Treatment

We’ve talked about the signs and the causes. Now let’s discuss how to treat dogs with eye allergies.

Dog Allergies Eyes Treatment

One of the most frequently asked questions is, can you use allergy eye drops on dogs? Natural saline eye drops are a safe way to try and flush out allergens from your dog’s eyes and prevent them from lingering and causing further irritation. 

However, for more persistent allergies, a steroid-based solution could be prescribed by your vet. Antihistamines are another possible line of treatment. Again, this would involve a visit to your doggy doctor. 

Dog Eye Allergies Home Remedies

Although eye allergies are not life-threatening, the symptoms they produce can make your dog highly uncomfortable and miserable. This is why many pet owners opt to use natural DIY remedies to improve their pet’s condition and provide relief. 

You can make your own saline solution for your dog’s eyes: 

  • Mix ¼ cup of warm water and ¼ teaspoon of salt. 
  • Dip a gauze pad into the solution and wipe from the corner outward, towards the ear. 

Another option would be camomile tea bags:

  • Brew the tea and leave to steep until the bag has cooled down. 
  • Take the bag and place it on your dog’s eye.
  • Hold in place for around 5 minutes (if you can) at a time.

Cod liver oil also promotes optical healing, so you can apply these drops to your dog’s eyes to provide relief.

Bear in mind, these solutions may not treat the underlying causes of your dog’s eye infections. Hence, you should only use these at your vet’s discretion.

Dog Eye Allergies vs Infection

Dog eyes allergies are often confused with eye infections. While they can present themselves in similar ways, they can be individually diagnosed by your veterinary practice. 

If using a saline solution, your dog eyes swollen allergies should improve within 48 hours. However, if your pooch has an eye infection, these drops may not be adequate to clear it. Your vet should be able to prescribe a suitable course of treatment to kill off the infection and alleviate the symptoms.

Typical signs include watery or red eyes, continual itching, and even swelling or hair loss around the head.

If you’re unsure of the reason behind your pooch’s predicament, your vet can carry out tests to diagnose the underlying problems. So, you can prevent prolonged exposure to their triggers. 

And, while dog eye allergies are highly common and manifest similar symptoms to other conditions — as we’ve seen, you can treat it at home or via a trip to the vets.
