Ask A Vet: These Tear Stains On My Dog’s Face Won’t Go Away. What Can I Do?

Why Tear Stains Develop in Certain Breeds

Many owners of light-colored dogs with short noses, such as Maltese or Lhasa Apsos, notice persistent reddish-brown stains beneath their pets’ eyes. This common cosmetic issue, known as tear staining, occurs when excess tears overflow and react with bacteria on the fur, leading to discoloration. While often harmless, it can be frustrating for pet parents seeking a clean appearance for their companions.

Dogs with shallow eye sockets or facial folds, like brachycephalic breeds, may not drain tears effectively through the nasolacrimal duct. This anatomical trait causes tears to spill onto the face instead of draining internally. Porphyrins, iron-containing molecules naturally present in tears, oxidize when exposed to air, creating the characteristic rust-colored stains. Diet, allergies, or blocked tear ducts can exacerbate the problem, though staining alone rarely indicates serious illness.

How Have Owners Tried to Address This Issue?

Over time, various products have emerged to manage tear staining, including dietary supplements and topical wipes. Some formulations contained antibiotics like tylosin to reduce bacterial growth linked to staining. However, the U. S. Food and Drug Administration has raised concerns about the unapproved use of such ingredients in pet products marketed for cosmetic purposes. Veterinarians caution against long-term antibiotic use without medical justification due to risks of resistance and microbiome disruption.

Experts recommend starting with a veterinary exam to rule out underlying causes such as eye infections, ingrown eyelashes, or duct abnormalities. Regular face cleaning with saline solution or veterinarian-approved wipes can help minimize buildup. Keeping facial hair trimmed reduces moisture retention. Switching to a high-quality, hypoallergenic diet may benefit some dogs, though results vary. Plastic food bowls should be avoided, as they can harbor bacteria that contribute to facial irritation.

What Safe Alternatives Exist for Managing Stains?

Are tear stains painful for my dog? Typically, tear stains themselves are not painful or itchy. However, if your dog rubs its face excessively or shows signs of eye discharge, squinting, or redness, consult a vet to check for irritation or infection.

Frequently Asked Questions

Can I use human makeup remover on my dog’s face? No, human cosmetic products often contain ingredients unsafe for pets, such as alcohol or fragrances, which can cause skin irritation or toxicity if ingested during grooming. Stick to products specifically formulated for canine use.

Will changing my dog’s water bowl eliminate tear stains? Switching from plastic to stainless steel or ceramic bowls may help reduce bacterial buildup around the mouth and face, which some believe contributes to staining. While not a guaranteed fix, it’s a simple, low-risk step worth trying alongside other preventive measures.
