What are you asking — what causes brown tear stains in dogs?

The presence of brown tear stains in canines is predominantly attributed to the build-up of porphyrins, inherent compounds present in tear secretions. When these porphyrins come into contact with oxygen and light, they undergo oxidation, assuming a brown hue and subsequently manifesting as unsightly discolorations on the fur surrounding the ocular region.

For those who require further information

The issue of brown tear stains in canines is a frequent worry amongst those who care for their beloved pets. This blemishing discoloration encircling the eyes can be attributed to the accumulation of porphyrins, innate compounds found in tear secretions. When these porphyrins encounter oxygen and light, they undergo a transformative process, leading to the manifestation of unsightly brown marks on the fur encompassing the ocular area.

To elaborate further on the topic, here are some interesting facts about brown tear stains in dogs:

  1. Breeds with prominent facial folds, such as Poodles, Shih Tzus, and Bulldogs, are more susceptible to developing tear stains. The folds create a warm and moist environment that promotes the growth of bacteria, leading to increased tear production and staining.

  2. Tears are not the sole cause of brown stains. The porphyrins present in saliva and urine can also contribute to the discoloration, especially in dogs that lick their paws and then rub their eyes.

  3. Poor diet and nutrition can play a role in the formation of tear stains. Excessive intake of artificial food additives, such as food colorings and dyes, may intensify tear staining in some dogs.

  4. Infections, allergies, and eye-related issues, such as blocked tear ducts or eyelash abnormalities, can exacerbate tear staining. It is crucial to address any underlying health concerns to effectively manage and prevent further staining.

  5. Regular grooming and cleaning of the eye area can help minimize tear stains. Using a gentle pet-safe eye cleanser or warm water, carefully wipe away any debris and excess tear stains. However, it is essential to consult with a veterinarian before using any products near your dog’s eyes.

In considering the significance of the topic, I would like to quote American author, Josh Billings, who said, “A dog is the only thing on earth that loves you more than he loves himself.” As responsible pet owners, it is our duty to ensure the well-being and comfort of our canine companions, which includes addressing tear stains and maintaining their ocular health.

The red/brown discoloration in tears comes from porphyrin. Porphyrins are iron containing molecules produced when the body breaks down iron. Porphyrins are excreted through the gastrointestinal tract, urine, saliva, and TEARS!

The characteristic reddish-brown color of dog tear stains is caused by an iron-containing dye molecule called porphyrin. When the body breaks down red blood cells, porphyrin is released. This molecule is excreted in the bile, tears, saliva, and urine of dogs.

What is causing the stains in dogs? This discoloration is caused by a chemical called porphyrin. Porphyrins are excreted primarily through bile and the intestinal tract, but in dogs a significant amount of porphyrin is excreted through tears, saliva and also urine.

Tear stains are the reddish stains that appear below some dogs’ eyes. They are caused, in the most direct sense, by porphyrin–a reddish-brown pigment found in tears. Porphyrin is produced as the body breaks down iron. This molecule is excreted through many different pathways, including the gut, saliva, urine, and–you guessed it–tears!

This video provides natural remedies for treating dog tear staining caused by a blocked tear duct. The first method involves cleaning the eyes with warm water and using a warm compress to potentially unblock the tear duct. Another option is to apply a warm tea bag as a compress, which has antibacterial properties. Massage can also be used to loosen the blocked tear duct by gently applying pressure in the corner of the eye. Additionally, organic unprocessed coconut oil can be applied topically to reduce tear staining and inflammation. It is recommended to apply a small scoop of coconut oil on the affected area at least twice a day for two weeks. Oral ingestion of coconut oil can also provide anti-inflammatory benefits, but should be started with small doses and gradually increased to avoid digestive issues.
