Do you have a dog that needs continual cleaning under the inside corner of the eyes, next to the nose? Do crusts sometimes form and cause irritation to the skin in that area? This is a common problem, especially for some breeds.
For lighter color dogs, the brown staining is prominent and causes many owners great anxiety. They desperately seek a cure for the problem. More important is to find the cause of the excessive tearing and staining rather than “cosmetic band-aid” treatments.
Dog Breeds with Tear Staining
Smaller breed dogs seem to be the worst afflicted with this problem. The “flat-faced” breeds with bulgy eyes are particularly prone. The skin folds around their flat noses become inflamed and quite painful. Some common breeds with tear staining are:
What Causes Tear Staining?
The brownish stain under the eyes and next to the nose is caused by the oxidation of excessive tearing. Normally tears enter tear ducts at openings near the inside corner of the eyes and drain into the nose. Our tear system works exactly the same way. That is why we have to blow our noses when we cry.
If tear production exceeds the draining capacity of the tear ducts, the tears spill over the eyelid and roll down along the nose. Blockage or inadequate tear duct openings will also cause tears to spill over the eyelids. Causes for these problems include:
