Fleas, Ear Mites and Infection

Fleas can also be a source of tear stains. Fleas require moisture to survive and the tears are a perfect source of that moisture. This can cause irritation along with staining from the flea dirt which is flea feces consisting of digested blood. Along with the fleas comes the associated problem of ear mites that are carried by the fleas. Ear mites can cause painful ear infections, besides the tears stains, and should be addressed immediately by your veterinarian.
