If your dog has reddish-brown marks beneath the eyes, you may be wondering, “Why does my dog have tear stains?”
The answer is usually related to excess tears, poor tear drainage, facial anatomy, or irritation around the eyes. Tear stains can affect small white dogs, but they are not limited to tiny breeds. Golden retrievers, labs, poodles, doodles, and mixed breeds can develop them, too.
As a trusted mckinney mobile dog groomer, Dive Into Dogs helps keep your dog’s face clean, comfortable, and adorable with gentle grooming and luxury spa services. Our lead groomer, Maddie, provides one-on-one care in a temperature-controlled van without cages or kennels.
Mckinney Mobile Dog Groomer: Why Does My Dog Have Tear Stains?
Tear stains form when tears spill onto the fur instead of draining normally through the nasolacrimal ducts. These ducts carry tears from the eyes toward the nose.
When the fur stays damp, natural pigments called porphyrins can oxidize and leave behind rust-colored, reddish-brown, or pink staining. The longer the hair remains wet, the more noticeable the stains may become.
According to veterinary resources from PetMD and the American Kennel Club, common causes include:
- Facial anatomy that affects tear drainage
- Narrow or blocked tear ducts
- Hair rubbing against the eye
- Allergies or airborne irritants
- Eyelid or eyelash abnormalities
- Eye infections or inflammation
- Dust, pollen, and outdoor debris
- Moisture that remains trapped around the muzzle
In some dogs, tear staining is mainly cosmetic. In others, it may signal discomfort or an underlying eye problem.
What Causes Tear Stains in Small and Large Dogs?
Flat-faced breeds and dogs with prominent eyes are often more likely to develop tear stains. Shih Tzus, Maltese, pugs, poodles, bichons, and similar breeds may have facial structures that make drainage more difficult.
However, large dogs can have tear stains as well. A golden retriever or lab may experience watery eyes from seasonal allergies, dust, grass, or irritation from hair near the eyes. Darker coats may simply hide the discoloration better.
Your dog’s coat texture also matters. Long, fluffy hair can wick moisture down the face. Curly coats may trap dampness close to the skin. If the area stays wet, your dog may develop unpleasant odor, skin irritation, or painful hot spots.
Late-August tear stains in North Texas
Late August in McKinney, Allen, Prosper, and Melissa can mean intense heat, dry grass, outdoor dust, and high pollen exposure. Dogs spending more time outside may encounter irritants that make their eyes water.
That does not mean Texas weather is always the root cause. It may simply make an existing drainage or allergy issue more noticeable.
If your dog’s eyes suddenly become watery, red, swollen, cloudy, or painful, contact your veterinarian before scheduling a cosmetic facial.

Mckinney Mobile Dog Groomer: When Should You Call Your Veterinarian?
A professional grooming appointment can remove surface buildup and keep the face cleaner. It cannot diagnose or treat eye disease.
Schedule a veterinary examination if you notice:
- Sudden or severe tear staining
- Tearing from only one eye
- Squinting or frequent blinking
- Pawing or rubbing at the face
- Redness or swelling
- Thick yellow, green, or foul-smelling discharge
- A cloudy-looking eye
- A change in eyelid position
- Signs your dog is struggling or in discomfort
Possible medical causes can include conjunctivitis, corneal irritation, glaucoma, blocked tear ducts, ingrown eyelashes, or eyelid conditions. Your veterinarian may examine the eye, test tear production, or check whether the tear ducts are draining properly.
Once medical concerns have been ruled out, regular grooming can help manage the appearance and moisture around the eyes.
How Do Blueberry Facials Help Dog Tear Stains?
A blueberry facial is a gentle, dog-safe facial cleansing service designed for the fur around your dog’s muzzle and eyes.
Despite the delicious name, it is not a snack and should never be allowed into your dog’s eyes. The blueberry part refers to the facial cleanser or spa treatment used by professional groomers. These products are typically made to clean facial fur, loosen buildup, and freshen the area.
A blueberry facial may help by:
- Removing dirt, food residue, and dried tear debris
- Softening crust around the muzzle
- Cleaning moisture-trapping facial hair
- Improving the appearance of stained fur
- Helping reduce odor caused by damp buildup
- Leaving your dog looking fresh and fluffy
It is important to understand what a blueberry facial does not do. It does not unblock tear ducts, stop allergies, cure an infection, or change how much your dog tears.
Think of it as a cosmetic and comfort-focused grooming service. It helps clean the fur while your veterinarian addresses any medical cause.
What Happens During a Professional Blueberry Facial?
At Dive Into Dogs, your dog receives calm, individualized attention from Maddie in our Sanctuary of Silence experience.
A typical facial service may include:
- A gentle inspection of the facial area
- Careful cleansing around the muzzle
- Softening of dried debris
- Thorough rinsing away from the eyes
- Gentle drying to reduce trapped moisture
- Light trimming when excess hair is holding moisture
- Positive reinforcement throughout the service
We use pet-friendly products and take care around sensitive areas. Your dog’s eyes are never treated as if they were a surface to scrub. The goal is a clean, comfortable face: not an aggressive attempt to erase every mark in one session.
Older staining may remain in the existing hair until it grows out or is carefully trimmed. Consistent cleaning and regular grooming can help prevent new staining from becoming as noticeable.

How to Help Prevent Tear Stains at Home
After your veterinarian confirms that your dog’s eyes are healthy, a simple home routine can help.
- Wipe the area gently with a clean, damp cloth.
- Keep facial hair trimmed to an appropriate length.
- Dry the face after drinking, bathing, or outdoor play.
- Wash food and water bowls regularly.
- Watch for seasonal allergy patterns.
- Avoid human products, harsh cleaners, and unapproved whitening products.
- Never use hydrogen peroxide, bleach, or strong fragrances near your dog’s eyes.
- Ask your veterinarian before using eye washes, supplements, or new topical products.
If the fur is matted or tightly packed around the eyes, do not attempt to cut it with household scissors. A professional groomer can safely manage the hair and reduce the risk of injury.
