|I disagree about little dogs having more allergies and sensitivites causing eye issue. Most small dog tear stains are due to genetics and the anatomy of the eye as it fits into the eye socket. Large eyes fit tightly in a small dog and as a result, they compress the tear duct that drains tears down into the nose. Because of the compression on this duct the tears spill over the eye and, depending on the bacterial and mineral content of the tears, will or will not stain. This has nothing to do with allergy, it is purely physical.
It is also true that dogs with hair close to their eyes often suffer irritation from the hairs rubbing the eye...coupled with a compressed or too small tear duct, these tears will run down the inside corners of the eyes and either cause stains or even collect dust and dirt buildup.
I had many large dogs for years and years, now I have only small ones and, while some of them do have tear stains from bacteria in the tears, NONE of them have allergies or are more sensitive to dust, etc.
