How to Fix Red Eyes in Dogs (Causes & Solutions)

Red eyes in dogs may be permanent or temporary depending on the cause behind it. Depending on the situation, your pet might have either one or both eyes that are red. Allergies can cause temporary redness of the eye, but underlying health issues or genetic health defects can cause permanent redness.

Red eyes occur when there are internal or external inflammations on the eyes, which causes a large amount of blood flow. Any condition that causes the enlargement of the eye’s blood vessels will lead to red eyes in dogs. Even though the cause of that red-eye might be insignificant, please consult a vet if you want to make sure.

Why Does My Dog Have Red Eyes?

In the list down below, I have listed several main causes of red eyes in dogs and major health disorders that can cause red eyes as a side effect. In addition, I have added several solutions that might relieve the pain of your dog!

1. Conjunctivitis (Pink Eye)

Conjunctiva tissue is a transparent membrane that covers the white part of the eye, and the disease conjunctivitis is the inflammation/infection of this tissue. If a dog gets a pink eye, it will result in redness and itchiness around the eyes, which can lead to discharge and crusting around the eyes as well (Highly Contagious).

Conjunctivitis can be caused by bad air quality such as smoke, dust, and aerosols. If your dog likes swimming, check the water quality since bad water quality can cause eye infections. In addition to water and air, make sure to prevent your dog from frequently rubbing his eyes since rubbing eyes with unwashed paws can also cause conjunctivitis.

Solutions to Conjunctivitis

Due to many causes that can cause conjunctivitis, it is best to take your dog to a professional vet for further diagnosis. If you are not able to take your dog to a vet, then try some of these products down below if you suspect that your dog is suffering from pink eye.

Formulated by Vetericyn Plus, the Eye Wash offers a pain-free solution for all pets, including cats and dogs. Providing safe relief by thorough washing, this bottle has been reviewed by thousands of pet owners, and it has been proven to work for dogs with pink eye and allergy symptoms.

Also created by Vetericyn Plus, this Eye Gel provides a painless product that is recommended by many veterinarians. Made with state-of-the-art equipment and technology, this bottle has been officially approved to solve problems such as eye abrasions, irritations, pink eyes, and allergies.

2. Glaucoma & Cataracts

Glaucoma is a disease of the optic nerve that occurs when there is increased pressure inside the eye due to improper drainage of the fluids inside the eye. While glaucoma can be caused by increased eye pressure, cataracts are mostly formed due to old age, which can be also seen as cloudy white spots in your dog’s eye.

Prominent symptoms of glaucoma are eye pain, discharge of water from the eye, swelling of the eyeball, and a cloudy or bluish eye. The increased pressure in the eye causes a pinch in the optic nerve, which is the source of vision. If the optic nerve is damaged, your dog’s vision is also affected as well.

Solutions to Glaucoma & Cataracts

Since your veterinarian can quickly assess the pressure in your dog’s eye, they can quickly determine whether the red-eye is caused by inherited diseases such as glaucoma. Please don’t try to get supplements to avoid appointments with a vet! I know that supplements cost less, but your vet’s advice can be priceless at times.

Patented by animal eye specialists, the Vision Supplement goes a long way for dogs with poor eye health. Providing the daily dose of needed ingredients, this supplement contains healthy nutrients and 12 antioxidants that help dogs with cataracts and glaucoma.

3. Eye Injury or Trauma

Injury to the eye can be caused by blunt objects and sharp instruments that come into direct contact with your dog’s eye. Some of the causes might be due to natural means, such as thorny bush, prickly branches, and irritated insects. If you can prevent your dog from going into risky environments, please do so!

Naughty people may also throw stones or other blunt objects at your dog, which can cause inflammation on the outer eye. These eye injuries and trauma can cause sharp objects to get into your dog’s eye, which can be a huge problem down the road if it is not treated immediately!

Solutions to Eye Injury or Trauma

As always, take your dog to a vet if you see blood formation on your dog’s eye due to past injuries and traumas. Any trauma to the eye can lead to serious cases if not treated properly, so please schedule an appointment with a vet!

Even though I have recommended this product in my previous section, I will mention it again here since this Eye Gel is also formulated for eye wounds. Due to its application to the eye, this product was made toxin-free and antibiotic-free to provide immediate relief to dogs with pain.

4. Allergens

Perceived as a threat to the immune system, allergens are substances that cause allergic reactions such as red or pink eyes, tears, wheezing, sneezing, itchy skin, runny nose, watery discharge, and even more.

Mostly found in the environment, common allergens in dogs are dust, pollen, and insect bites. You can also detect allergic reactions if you have given your dog a new type of food, and if you see these symptoms (listed above), your dog is probably allergic to that food.

Solutions to Allergies

If you want to figure out the exact source, you can go to your vet for help, which can include various skin and blood testings to figure out the root of this problem. If you think that you can figure out this problem all by yourself, I have listed several solutions down below that might help.

For red eyes, the Eye Wash by Vetericyn Plus will do the job since it was also made to relieve allergy symptoms for dogs. If you have any doubts regarding this product, be sure to visit the customer review section for further evaluation of VP Eye Wash.

If you want a supplement for allergies, Zesty Paws Chews will do the job by providing the necessary ingredients for a strong immune system. Containing vitamins, protein, fiber, and various antioxidants, these supplements support digestive and immune health through its natural ingredients.

5. Foreign Objects

Foreign objects refer to any external material whether microscopic or macroscopic that enters the eye and causes irritation. For example, objects such as leaves, grass seeds, dust, and wooden splinters can accidentally form their way into your dog’s eyes, which can cause red eyes in dogs.

If that object is visible, you can soothe your dog into stillness and get the object out. However, if the object has penetrated deep into the eye or inner lids, please seek the help of a professional veterinarian for further treatment.

Solutions to Foreign Objects

DO NOT attempt to remove objects that have penetrated the flesh of the eyelid or the eyeballs. You may add salt to the injury instead of salvaging the situation. The eye is a very sensitive organ that should be handled with utmost care. You might think that you are helping your dog out, but your actions can end up jeopardizing your dog’s vision.

6. Hair/Fur

Even though this might not happen as much, excess hair can form over your dog’s eye. If that is the case, hair can fall into your dog’s eye, which can cause irritation (red eye). To prevent this, you can either shave off the excess hair yourself or go to a professional groomer for a nice hair cut.

If you are cutting the hair yourself, please be careful and extra gentle around the eyes. If you are not careful enough, you will end up poking the eyes of your dog, which is not good for your dog. Practice a lot beforehand before trying it on your dog!

Solutions to Hair/Fur

Solutions to this problem were already mentioned since you just need to cut the excess hair off your dog. Make sure to regularly cut your dog’s hair since well-groomed hair is a great way to maintain a healthy coat and a healthy lifestyle.

If you need help with maintaining a healthy-looking coat, be sure to check out the pet grooming brush for dogs. Being a durable tool for hair-shedding canines, this brush can work wonders in just ten minutes. Make sure to check out the customer reviews at this link!

Why Is My Dog’s Eye Red on Only One Side?

In some situations, only one side of your dog’s eye will turn red while the other side remains normal. In this case, we can probably assume that a certain side experienced an injury or a trauma by a foreign object.

However, some conditions like glaucoma or conjunctivitis can form only on one side and can spread to the other eye if left untreated. Due to several reasons, make sure to inspect your dog regularly for its eye color.

If you see your dog’s eye changing color, you should be alarmed since that doesn’t happen too frequently. Be observant, and make sure to spend time with your dog since that is the best way to notice even the smallest change in your dog.

What Is the Red Rash Around My Dog’s Eye?

As long as the rash is not affecting the eye color, the red skin around your dog’s eye might occur due to skin infection or allergic reactions. If the eye is not affected, then you don’t need to be deeply concerned since you just have to treat the rash around it.

Your vet will diagnose the skin around the eye and offer proper treatment depending on the cause. If it is caused by parasites, then you will be advised on how to get rid of these parasites to avoid any future recurrences.

What Causes Discharge for Dogs With Red-Eyes?

Eye infections or diseases are usually accompanied by watery discharge from the eye. A bacterial infection on the eye will produce pus-like discharge from the eye that is likely to be cream or yellow-green in color.

Conditions such as conjunctivitis cause itchiness and watery discharge from the eye while glaucoma will produce a thick semisolid discharge that is also a major cause of boogers in dogs.

In addition, watery and tear-like discharge is caused by irritation to the eye by allergens or by foreign objects. If observed, please check for bloodshot eyes, and either take your dog to a vet or call the vet to come and treat your dog within his comfort zone.

How Are the Red Eyes in Dogs NormallyTreated?

According to, “Your veterinarian will choose treatment for your dog’s eye redness based on the underlying cause. Some treatments will include a topical medication that goes into your pet’s eye, and in some cases, your veterinarian may also prescribe injections or oral medication.”

Home Remedies for Red Eyes in Dogs

Most of these home remedies will help in reducing inflammation, itchiness, and soreness of the red eyes in dogs. Used by many veterans, these methods have been proven to be effective and very useful.

Since serious conditions such as conjunctivitis, eye tumors, and glaucoma cannot be treated with home remedies, make sure to double-check with your vet before trying out these remedies at home!
