There are different causes for dog tear stains, and several remedies depending on the cause. It’s important to note that tear stains can be the result of a more serious problem, and in many cases simply removing the tear stain will not prevent future stains from occuring without continued treatment. The following are the 5 most common causes:

Excess Tearing

Excess tearing (or epiphora) is usually a response to an environmental irritant and may be a sign that your dog has allergies. The discoloration is actually caused by bacterial and yeast growth.

Blocked Tear Ducts   
This is going to sound strange, but dog’s tears normally drain through their nose. When the tear ducts are blocked tears overflow which results in the same discoloration.   

Teething
Here is another cause most pet owners don’t realize. Teething is an uncomfortable process for dogs and all the changes happening in their mouth puts pressure on their tear ducts causing overflow, like in number two, which then takes us back to the discoloration described in number one.

Parasites

Fleas use a dog’s tears as their watering hole. If fleas go untreated the feces, left behind by the fleas, will build up around the dog’s eyes and block the tear ducts, leading to overflow and discoloration. Make sure that this is not what is causing your dog's tear stains.

Thankfully there are some solutions to dog tear stains, including products that can help remove and/or prevent further occurrences. One of these products is Angle’s Eyes. Angel’s Eyes works to prevent further tear staining; you can begin to see results in three to five weeks depending on the growth rate of your dog’s coat. You will want to continue to trim off the stained coat and a new coat will grow in free of stains. Angel’s Eyes will also help to eliminate staining around the mouth due to licking.

If your dog is on the list under the fifth cause (genetics), you might have to deal with tear stain removal throughout your dog’s life. Try out a few different products and find out what works best for your dog. As always, it’s important to take your dog to your local vet for regular checkups. If tear staining is a problem, you will want to make sure that your dog is not infested with fleas or ear mites, in which case another form of treatment would also be recommended.
