Tear stains on dogs are reddish-brown stains that extend from the inside corner of the eye onto or down the sides of the dog's muzzle
. They are caused by variations in the eyelid structure, which can cause tears to drain onto the face instead of down the nasolacrimal duct
. Porphyrins, iron-containing molecules produced by the body when it breaks down iron, are excreted through the gastrointestinal tract, urine, saliva, and tears, and can contribute to tear staining
. Dogs with short noses, large eyes, a flat face, white fur, or congenital tear duct abnormalities are more likely to develop tear stains
. While excessive tear production is not the primary cause of tear stains, it can contribute to the problem
. To treat and prevent tear stains on dogs, consider the following:
- Keep the hair around your dog's eyes and nose as short as possible to reduce the area where tears can accumulate and stain
- Use mild antibiotics, such as Lincocin or Tylosin, for short periods of time, but consult your veterinarian before administering any medication
- Consider giving your dog probiotics, which may help decrease tear staining
- Use a slightly damp washcloth to wipe the face at least twice daily, and clean under the eyes with an ordinary contact lens cleaning solution to help keep things neat and tidy
- Experiment with stain removal methods, such as applying Visine to the fur or using hydrogen peroxide on the muzzle (avoiding the eyes)
Remember that each dog is different, and it may take some trial and error to find the most effective approach for your pet
. If your dog's tear stains worsen or become infected, consult your veterinarian for further guidance
