Does your pooch have rust-colored stains under his eyes? The most common reason for this problem is the excessive production of tears, which is technically called ‘epiphora’. The reddish color is caused by an iron-containing molecule called ‘porphyrin’ that is excreted by the animal’s body via the feces, urine, tears, and saliva.
Irritation of the tear ducts is often caused by the hair on the skin folds surrounding the eyes. As tearing increases, so thus staining. Some canine breeds are more prone to forming tear stains, such as the Shih Tzu and Pekingese. Their eye sockets are shallow thus, causing the tears to spill off easily onto the surrounding areas. Most tear stains are not something to be worried about, although they could be unpleasant to look at. However, excessive tear production could also be caused by more serious issues like an underlying eye infection, ingrown lashes, or even glaucoma. If a yeast infection is present, the stains usually appear brownish and are accompanied by a pungent odor. To avoid further problems, a trip to a vet clinic London ON is warranted.
