Causes and When to See a Vet"},"content":{"rendered":"\n

It\u2019s unsettling to look at your dog and suddenly wonder, \u201c<\/em>Why is my dog\u2019s eye red?<\/em>\u201d<\/em> Whether it appeared overnight or after a walk in the woods, a red eye can signal anything from a mild irritant to a medical emergency. Your puppy may have rubbed its face on the carpet, played too roughly at the dog park, or stuck its head out the car window and caught some debris. <\/p>\n\n\n\n

Although some causes, such as dust or dry air, are harmless and resolve quickly, others, like glaucoma or a scratched cornea, require immediate attention. It’s essential for all pet parents to recognize the signs so they can determine when it’s time to visit the vet.<\/p>\n\n\n\n

What Causes Red Eyes in Dogs?<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

If your dog has red eyes, it\u2019s more than just a cosmetic issue. It\u2019s a sign that something might be bothering their eyes. Red eyes in dogs have many causes, and pet owners should know about the following: <\/p>\n\n\n\n

Conjunctivitis (Pink Eye)<\/h3>\n\n\n\n

Conjunctivitis in dogs <\/a>is a common condition that inflames the conjunctiva, the lining of the eye, causing redness, excessive blinking, swelling, and a yellow or greenish discharge. This is an inflammation of the surface of the eye (cornea) that can be caused by infections (bacterial or viral), trauma, or allergies, and is often contagious among dogs.<\/p>\n\n\n\n

Allergies<\/h3>\n\n\n\n

Dogs can react to various substances, including pollen, mold, food, dander, and even cleaning products. If your dog has red eyes and watery discharge, discomfort, along with sneezing or itching, allergies might be the issue, especially during spring. Such conditions are treated with oral medication, such as antihistamines, or eye drops. <\/p>\n\n\n\n

Irritants Like Dust or Smoke<\/h3>\n\n\n\n

Just like people, dogs\u2019 eyes can get irritated by environmental factors. A walk on a windy day or exposure to smoke from a barbecue can cause temporary redness.<\/p>\n\n\n\n

Foreign Object in the Eye<\/h3>\n\n\n\n

A grass seed, a speck of dirt, an eyelash trapped within the eye, or sand can get lodged in your dog\u2019s eye, which can lead to redness, bloodshot eyes, and pawing at the face. This situation is quite normal, especially in adventurous canines that love running through bushes and tall grass. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Injuries or Scratches<\/h3>\n\n\n\n

Rough play, a swipe from another pet, tree branches, or toxic gases\/fumes can cause eye trauma. Eye ulcers are commonly caused by trauma, and this typically leads to redness, squinting, excessive tearing, or bleeding. <\/p>\n\n\n\n

Glaucoma or Increased Eye Pressure<\/h3>\n\n\n\n

This serious condition requires urgent medical attention, as it can lead to permanent blindness. It is caused by increased eye pressure and a buildup of fluid in the front part of the eye. The common signs of glaucoma include bulging, redness, pain, eye haziness, and changes in vision. There are several reasons why it occurs in dogs, including uncontrolled or poorly regulated diabetes, hereditary factors, or other disease processes.<\/p>\n\n\n\n

Dry Eye (Keratoconjunctivitis Sicca)<\/h3>\n\n\n\n

When tear production decreases, the eyes become dry, red, and irritated, often producing mucus or eye gunk. This leads to a dog losing its normal protective function of the eye surface, and is particularly common in breeds such as Pugs, Shih Tzus, and Bulldogs. It\u2019s worth noting that this issue often goes hand in hand with other conditions, such as diabetes. <\/p>\n\n\n\n

\u201cI got the Maven sensor for my 14-year-old Chihuahua mix with heart and trachea issues. It gave me back peace of mind <\/strong>– I can track her RRR, BPM, drinking, and activity anytime and know instantly if something\u2019s wrong. Highly recommend!\u201d <\/em><\/p>\n\n\n\n

When Should You Be Concerned?<\/h2>\n\n\n\n

It\u2019s natural to worry when your dog\u2019s eye suddenly looks irritated, especially if other symptoms appear. If you’ve been asking, \u201cWhy is my dog\u2019s eye red and swollen?\u201d or noticed your canine friend acting off, here are four warning signs that mean it\u2019s time to call the vet. <\/p>\n\n\n\n

    \n
  1. Eye appears swollen or oozing \u2014<\/strong> If the eye is puffy or producing yellow or green discharge<\/a>, it may be due to an infection, injury, or blocked tear duct. For example, after a hike, a stick or plant may have scratched your dog\u2019s eye.<\/li>\n\n\n\n
  2. Dog is pawing or rubbing its eye constantly \u2014<\/strong> Frequent rubbing can worsen the issue and might mean something is stuck in the eye or it\u2019s painful. This occurence can also lead you to wonder, \u201cWhy is my dog licking his paws<\/a>?\u201d,<\/strong> which is actually a common sign of discomfort.<\/li>\n\n\n\n
  3. Sudden onset of redness with behavioral changes \u2014<\/strong> A quick change in eye color, plus anxiety or hiding, could indicate something serious like glaucoma or trauma.<\/li>\n\n\n\n
  4. Accompanied by lethargy or discharge \u2014 <\/strong>A dog with red eyes and tired behavior might have a systemic infection or fever. If your furry friend has red eyes and tires easily, seek vet care immediately.<\/li>\n<\/ol>\n\n\n\n
