What are tear stains?
The reason why pets have tear stains. It is caused by porphyrins. Porphyrins occur when blood red blood cells, which naturally contain iron, break down. Porphyrins in dogs are excreted from tears, saliva, and urine. Tear stains occur when tears and saliva containing porphyrins remain on light-colored coats for a period of time, especially when exposed to sunlight, and become darker.
If the tear stains are brown in color rather than rusty red, it is usually because of fungal and bacterial infections in the hair near the tear stains due to prolonged wetting in the tears, which can also make the tear stains stink and give the pet an unpleasant body odor.
The amount of porphyrins in tears is related to the animal's breed, health, diet, and living environment.
