A dog’s eyes have a lot in common with ours because it is an active organ that constantly adapts to light and focuses on objects in its environment. However, there are still differences, for example, dogs have a third eyelid and a blinking membrane located in the inner corner of the eye. It helps to protect the eyeball from scratches or inflammation reactions, and these can often be the causes of red eyes in dogs.

Untimely assistance can bring you and your pet even more problems, so we do not recommend waiting an hour after the injury. Your best bet is to make sure that your dog is really okay.

Dog Allergies Caused Red Eyes

Corneal Ulceration

This can cause various dangerous bacteria, an ulcer can perforate a pet’s cornea in as little as 24-48 hours. Antibiotics are not the most beneficial prescription, but if this is the case, their absence increases the risk of loss of vision. The main thing is to strictly follow all the doctor’s prescriptions, there is no need for amateur performance, but a good treatment plan and specialist control over the situation.

Dog Eye Conjunctivitis

Conjunctivitis can be caused by bacteria or viruses. If your pet has severe conjunctivitis, it can be painful. So even without a corneal ulcer, you can see how it squints. Anytime you see your pet squinting, you will always need to ask your veterinarian for the corneal stain on his eyes. This ensures that there are no ulcers, as is sometimes the case with conjunctivitis. In some cases, it can be passed on to you or other dogs. It shouldn’t be contagious if it’s caused by allergies, irritants, dry eyes, or other common causes. Viral conjunctivitis is rare in dogs but can occur with the canine plague and canine herpes. Good hygiene is always the best practice. But you also may need to flush your pet’s eyes with saline or herbal tea every few hours. Herbal tea or homeopathic eye drops can also help in dog-red eye treatment.


What does it mean when your dog’s eyes are red? It may be Glaucoma. It outwardly represents a gray-green clouding of the lens, and in essence, this disease threatens the dog with loss of vision. The disease develops very slowly, and in its initial stages, the dog may not be bothered by anything. In order, under this condition, to ensure the proper level of preventive measures, in addition to the need for regular examination by a specialist, the following points should be taken into account:

  • The development of the disease is most susceptible to animals over 6 years old.
  • Genetic predisposition is of great importance in the development of glaucoma, so it is useful to find out if any of your dog’s closest ancestors suffered from this disease. For the same reason, the treatment of one patient with glaucoma of the eye must necessarily take place in conjunction with preventive measures aimed at preserving the second eye.
  • Diagnosing diabetes in a dog, one or another cardiovascular disorder, as well as hypertension, can be also the cause of canine red eyes.
  • The eye injury.

Poor Conformation

Some breeds have many folds and loose skin, but they are also known for their eyelid problems that cause red eyes. The eyelids may collapse, leaving the eyes unprotected. And these problems are serious because they almost always require surgical correction to prevent serious damage to the eye. Sometimes hair grows on the inside of the eyelid, which not only causes redness but can also lead to corneal ulcers. This is a rare problem of a dog’s eye irritated and red eyes as result, but a common symptom is when your dog squints or closes his eyes.

Dry Eye Syndrome
