Closer Look: Tear Stains & Eye Boogers

The next in our closer look mini series is eye boogers and tear stains and why they happen.

If you’ve ever looked at your dog and noticed eye boogers, tear stains, or a little gunk in the corners of their eyes, you’re definitely not alone. Eye discharge is one of the most common things pet parents ask about — and while it’s usually normal, sometimes it can signal something that needs attention.

Let’s take a closer look at what’s going on behind those sweet, expressive eyes.

Why Dogs Get Eye Boogers

Just like humans, dogs produce tears to keep their eyes clean, lubricated, and protected. As those tears dry, they can leave behind a little debris — often called “eye boogers.”

Common, harmless causes include:

• Normal tear production

• Dust or pollen

• Sleep crusties (just like us!)

• Windy car rides

• Mild irritation from the environment

These boogers are usually soft, light‑colored, and easy to wipe away.

When Eye Discharge Might Be a Concern

Some types of discharge can indicate irritation or infection. Keep an eye out for:

• Yellow or green discharge

• Excessive tearing

• Redness or swelling

• Squinting

• Rubbing or pawing at the eyes

• A sudden increase in discharge

If you notice any of these, it’s time for a vet visit. Groomers can clean around the eyes, but we cannot diagnose or treat eye issues.

Why Tear Stains Happen

Tear stains — those reddish‑brown streaks under the eyes — are especially common in light‑colored dogs and breeds with short snouts or prominent eyes.

They happen because of:

1. Excessive Tearing (Epiphora)

When tears spill over instead of draining properly, they soak into the fur and leave stains.

2. Porphyrins

Tears contain natural compounds called porphyrins, which turn reddish‑brown when exposed to air. This is what causes the staining.

3. Facial Structure

Breeds like poodles, shih tzus, maltese, bulldogs, and doodles often have shallow tear ducts or hair that directs tears onto the face.

4. Allergies or Irritation

Dust, pollen, food sensitivities, or even plastic bowls can contribute to tear staining.

5. Blocked Tear Ducts

Sometimes tears simply can’t drain properly.

What Groomers Can Do

During grooming, I can:

• Gently clean the eye area

• Remove dried debris

• Trim hair around the eyes to reduce irritation

• Keep the face tidy to help prevent buildup

What I cannot do is treat infections, diagnose tear duct issues, or use medicated products — those require a veterinarian.

How You Can Help at Home

A few simple habits can make a big difference:

• Wipe the eye area daily with a soft, damp cloth

• Keep facial hair trimmed

• Use stainless steel or ceramic bowls

• Monitor for allergies

• Keep the area dry to prevent yeast buildup

If tear staining suddenly worsens or becomes smelly, sticky, or irritated, a vet visit is the safest next step.

Healthy Eyes = A Happier Dog

Eye boogers and tear stains are usually just part of being a dog, but understanding why they happen helps you know what’s normal and what needs attention. With regular grooming, gentle at‑home care, and veterinary support when needed, your pup’s eyes can stay bright, comfortable, and healthy.
