Reasons for Your Dog’s Swollen Eyes

Below is a list of possible reasons for your dog’s swollen eyes. Some of these explanations are more serious than others, but you should learn about everything that could be causing this.

1. Allergies

A severe allergic reaction can cause your dog’s eyes to swell up. This means that your dog needs immediate emergency medical attention. If their eyes are swollen due to allergies, they might also experience problems with breathing properly.

  • Hives
  • Swollen face

2. Glaucoma

Some dogs develop glaucoma as they get older. This is a serious condition that affects the eyes, and it can even lead to blindness in the more advanced stages. There are certain breeds that are more likely than others to develop this condition, including Beagles, Basset Hounds, and Siberian Huskies.

A few of the other symptoms of glaucoma to look for in your dog include:

  • Watery eyes
  • Cloudy cornea
  • Bulging eyes
  • Whimpering due to eye pain

If you suspect that your dog has glaucoma, you should get them to the vet as soon as possible. There are numerous treatments for this condition, though it is not curable. It is possible that your dog could require surgery.

3. Injury to the Eye

A dog’s eye might swell up if it is injured in some way. If your dog is a big digger, it could accidentally scratch its own eye. This is not uncommon with these animals, but the injury will need to be treated quickly.

If one or both of your dog’s eyes are swollen, you should do a visual inspection to check for scratches or other types of injuries. If you happen to notice anything, you’ll want to get your dog to the vet.

When you take your dog to the vet, they will check your dog’s eyes out and look for any injuries. If one of their eyes has a scratch, they might just want to put a cone on them until the eye heals. This will keep your dog from causing further damage to their eyes.

Depending on the severity of your dog’s eye injuries, surgery might be needed. Your vet will make a recommendation based on the nature and severity of the injury. The sooner you get your dog looked at, the more likely it is that you’ll be able to save the eye. 

Even a minor scratch on their eye can get infected, which could mean having to get the eye removed. A bacterial infection in the eye is the absolute last thing you want for your canine companion.

4. Blepharitis

Blepharitis is a condition that affects the outer skin of a dog’s eyelids. It can cause your dog’s eyes to appear inflamed and even bulging out. This condition can affect just one of their eyes or both. It can lead your dog to scratch or rub their eyes, which can cause even more damage to them.

Some of the other symptoms of Blepharitis to look out for include:

  • Sudden hair loss
  • Scaly skin
  • Thickening of the eyelids
  • Corneal inflammation
  • Torn off the skin around the eyelids

There are a number of things that can cause Blepharitis but it is usually the case that a dog was born with it. It’s also possible that it developed as a result of a bacterial infection. There are a couple of different types of bacteria that can cause this to occur.

The treatment for this condition largely depends on the cause. Your veterinarian will take a close look at your dog’s medical history and perform a thorough examination before making any recommendations.

When to See the Vet

Your veterinarian will perform a thorough inspection of your dog’s eyes and body to determine the cause of the swelling. They may also want to take a blood sample to get a better understanding of what is going on. It may be necessary to leave your dog overnight for observation, depending on what the cause of the swelling is.
