What are tear stains, and what dogs are prone to them?
The tear stains problem is very common in small dogs with a light coat colour, such as Terriers, Maltese dogs, Bichons, Shih-tzus, Poodles, etc. These breeds have a special structure of the eyeball. However, cats often suffer from tear stains as well, especially Persians. Tear stains change the colour of the coat under the eyes. The hair there can get a brown or pink hue, and sometimes it is covered with sticky brown secretions. The latter has essentially the same nature as the secretion of the human eye in the morning. The pinkish-brown hue is caused by bacteria and yeast.
