Why is my dog Eyes - Tear Staining

Introduction

As a responsible dog owner, it's essential to be aware of the various signs and symptoms that can affect your furry friend's health. One common issue that many pet owners encounter is tear staining in dogs. Also known as red or brown staining around your dog's eyes, this condition can be more than just unsightly – it can also signal potential underlying health problems.

In this article, we will delve into the world of tear staining in dogs, exploring its causes, symptoms, and preventive measures to ensure your canine companion remains healthy and happy.

Understanding Eyes - Tear Staining

Tear staining in dogs occurs when tears mark the surrounding fur around a dog's eyes. These stains can appear as red or brown smears under a dog's eyes and are usually caused by the evaporation of tears that contain a compound called urobilinogen (UBG). UBG is produced when old red blood cells break down, which releases this pigment into the skin.

What Causes Tear Staining in Dogs?

There are several factors that contribute to tear staining in dogs:

• Anatomy: The shape and size of a dog's eyes, eyelids, and tear ducts can all play a role. Some breeds may have narrower or shallower tear ducts, making it more difficult for tears to drain properly.
• Tear composition: Dogs produce two types of tears: basal tears (excreted continuously) and reflex tears (released in response to irritation). Basal tears are richer in UBG than reflex tears, which means that if your dog's tear ducts are not functioning correctly, the tears may contain higher levels of UBG, leading to persistent staining.
• Facial conformation: Certain facial features, such as a flat face or short nose (brachycephalic breeds), can increase the likelihood of tear staining due to reduced space for the eyes and eyelids.
• Health and allergies: Any number of health issues – from eye infections to respiratory problems – can lead to increased tearing and subsequent tear staining.
• Age and breed: Some breeds, such as Pugs, Shih Tzus, and Bulldogs, are more prone to tear staining due to their facial anatomy.

Common Causes of Eyes - Tear Staining

While the underlying causes of tear staining in dogs can vary, some common culprits include:

• Dental problems: Gingivitis and other dental issues can cause inflammation and discomfort, leading to excessive tearing.
• Eye infections: Conjunctivitis (pinkeye) or more serious issues like uveitis can occur when the eye's inner layer becomes inflamed.
• Allergies: Intolerance to environmental allergens such as dust, pollen, or even skin allergies can cause eyes and nose itching, leading to excessive tearing..
• Sinus problems: The sinuses are closely linked with the tear ducts. When the maxillar sinus is inflamed (as in cases of a dental tooth decay), redness around eye may be one manifestation.

When to See a Vet About Eyes - Tear Staining

If you suspect your dog's tear staining is more than just a cosmetic issue, it's crucial to have it checked by a veterinarian.

Indicators that necessitate an expert examination include:

• Rapid or severe staining
• White stringy mucus at dog nose and eyes area
• Eye discharge other than white and clear as it can be contaminated with fungal growth from the corner of eye, indicating an infection.
