Tear Stains In Dogs – Cause & Treatment

What are tear stains? What causes them and how can you treat them? In this article we discuss how you can easily eliminate those rusty coloured stains from your dog’s face! Many cute dogs especially light coloured ones have their face marked with tear stains.

What Causes Tear Stains?

Dog tears cause tear stains. Tearing is a natural and essential process in dogs. Tearing keeps your dog’s eyes and membranes lubricated and hydrated. Different dogs will have different tearing rates. Some dogs tear more than others and such dogs would be more prone to tear stains.

What Makes them Red / Copper Coloured?

Like humans, dogs recycle their red blood cells. Once these red blood cells reach the end of their cycle, they are broken down into other forms for the body to process. During this breakdown process a group of compounds called porphyrins are created. These porphyrins contain iron and are mostly removed from the body via the urine and faeces. However these can also be removed from the body through saliva and tears. When the iron in these porphyrins comes into  contact with air, it undergoes an oxidation reaction and forms iron oxide, in other word rust! So in reality those red stains are rust stains!

In some dogs you also see stains around the lips and skin folds. For example, British bulldogs often have the inside of their face folds stained. Dogs that have a tendency to lick their paws a lot will also develop these stains on the paws. Some dogs are more prone to these stains. The reason for this is that these dogs will produce more porphyrins . Geneticists believe that the amount of porphyrins that a dog produces is genetically related.

Tear stains are more of a problem in light coloured dogs as they are easier to stain. However staining will also happen to darker coats.
