There are a host of reasons why your dog might develop an eye infection, but whatever the cause, eye infections in dogs can range from uncomfortable to downright painful and require immediate treatment to avoid complications. Learn about common causes of eye infections in dogs and how they are treated.
Types of Eye Infections Commonly Seen In Dogs
There are a few different types of eye infections that could cause your canine companion to experience discomfort, redness or sensitivity to light. Below are 4 of the most common types of eye infections in dogs:
- Conjunctivitis (Pink Eye)- an inflammation of the mucous membrane that covers the outer portion of the eyeball and the inside of the eyelids
- Inflammation of the cornea
- Tear gland issues or physical abnormalities of the eyelid
- Uveitis - an inflammation of one or more inner structures of the eye such as the iris, ciliary body, or choroid
Dog Eye Infection Causes
The causes of these various types of infections also differ from case to case. If your pooch is diagnosed with an eye infection, one of these factors could be triggering your pup's eye infection:
- Viruses (distemper, herpes, hepatitis, or canine influenza)
- Bacteria (canine brucellosis,leptospirosis, canine ehrlichiosis, or Lyme disease)
- Fungus spores
- Irritants or allergens, such as smoke or shampoo
- Foreign matter or debris (dirt, grass seed, or even your dog's own hair)
- Trauma
- Parasites
- Scratch or cut on the cornea
Not All Eye Problems In Dogs Are Infections
In some cases, your dog may display the signs of an eye infection, but actually be experiencing a different type of eye problem.
Some of the eye conditions in dogs that are commonly assumed by pet owners to be infections include glaucoma, tear duct problems or eye defects, dry eye, vitamin deficiency, exposure to or ingestion of toxins, tumors, cherry eye, or structural problems of the eye itself such as entropion.
Like infections, these eye issues can be painful and require veterinary care as soon as possible.
Conditions such as glaucoma, while not an infection, cause extreme pain and need the attention of a vet right away.
Symptoms of Eye Infections in Dogs
If your dog's eye is infected, you may notice one or more of the following symptoms. Eye infections require treatment and may become severe if left untreated. If your dog is displaying any symptoms of an eye infection, contact your vet to book an appointment.
Signs of eye infections in dogs include:
- Redness of the eye or surrounding the eye
- Swelling around eye
- Watery discharge or tearing
- Thick, smelly discharge
- Squinting and blinking
- Holding eye closed
- Sensitivity to light
- Pawing or rubbing at the eye
Dog Eye Infection Treatment
Treatment for your dog's eye infection will depend upon the underlying cause but could involve a combination of topical and oral medications such as antibiotics or anti-inflammatory drugs, a single topical medication, or in some cases, surgery.
- If a bacterial infection is found to be the underlying cause of your dog's eye infection, antibiotics and eye drops will typically be prescribed.
- When allergies are the suspected cause of eye infections in dogs, the vet may prescribe an antihistamine to help soothe your pup's eyes.
- If a foreign body or debris is irritating the eye, your vet may need to remove it while your dog is under sedation or local anesthetic.
- Blocked tear ducts typically require surgery, followed by eye drops and antibiotics.
- Dogs suffering from dry eye orkeratoconjunctivitis sicca (KCS) may be prescribedmedications such as cyclosporine or tacrolimus to help stimulate tear production.
- Eyelid or eyelash abnormalities that cause the lashes to rub against the eyeball are generally treated with surgery to correct the issue.
My dog has an eye infection, what should I do?
The fact is that if your dog is experiencing any eye sensitivity, irritation, or pain, it's time to head to your vet.
Your veterinarian will be able to conduct a thorough eye exam to determine the cause of your pup's symptoms and provide effective treatment to help your dog's eyes feel better. Left untreated eye infections can become severe and may result in loss of vision.
