Different breeds of dogs can sometimes produce colored tears that leave noticeable stains on their fur, especially on white or light-colored dogs. This happens because the stain is more visible on light fur, and often these breeds have extra hair around their eyes that can block the tear ducts.
What Causes Tear Stains?
The process starts with the tear ducts. When these ducts get blocked—whether by excess hair growing near the eyes, shallow eye sockets, or eyelids that roll inward—tears can’t drain properly. This leads to the buildup of stained tears on the fur. Breeds like Poodles, Cocker Spaniels, Pekingese, Shih Tzu, Maltese, and Pugs are particularly prone to this issue.

Why Do Dogs Shed Excess Tears?
There are a few reasons why your dog might produce more tears than usual. For some dogs, excessive tearing is just a genetic trait. In other cases, it could be due to health issues such as:
- Eye injuries or hair getting into the eyes
- Dry eyes or glaucoma
- Corneal ulcers or eye infections
- Cataracts or inflammation
- Allergic reactions
If your dog seems to be tearing up more than normal, it might be a good idea to watch for signs of irritation, like scratching or rubbing around the eyes. Long fur around the eyes can also cause discomfort if it isn’t properly trimmed.

What Can You Do About It?
If you notice tear stains on your dog, it’s important to figure out the cause. Check for any allergies or irritants in your dog’s environment, and if the problem persists, consult your veterinarian. They can help diagnose whether it’s just a natural trait or if there’s an underlying medical issue.
For a simple home remedy, you can mix one teaspoon of hydrogen peroxide with a bit of cornstarch to create a thick paste. Gently apply the paste to the stained areas—being careful to avoid your dog’s eyes—and let it sit for about two hours. Afterwards, wipe the paste off with a damp cloth and brush your dog’s fur to smooth it out.
By keeping an eye on your dog’s overall eye health and maintaining regular grooming, you can help manage and reduce the appearance of tear stains.
