Mucous membrane irritation

Mucosal irritation is a common problem in dogs that can have various causes. The mucous membranes are the moist tissues that cover the internal surfaces of the body, such as the nose, mouth, eyes, ears, gastrointestinal tract and genitals. They protect the body from infection and dehydration, but they can also become irritated, inflamed or injured.

Symptoms of mucosal irritation

The symptoms of mucosal irritation depend on which mucosa is affected and how severe the irritation is. Some common signs are

  • Sneezing, coughing or runny nose
  • Red, watery or pus-filled eyes
  • Itchy or sore ears
  • Vomiting, diarrhea or loss of appetite
  • Blood in the urine or stool
  • Sores or ulcers in the mouth or on the genitals

Causes of mucous membrane irritation

There are many possible causes of mucosal irritation in dogs, such as

  • Allergies to pollen, dust, food or other substances
  • Infections caused by bacteria, viruses, fungi or parasites
  • Chemical irritants such as cleaning agents, fertilizers or medication
  • Mechanical irritation caused by foreign bodies, injuries or bites
  • Autoimmune diseases in which the immune system attacks its own mucous membranes
  • Cancers that cause the growth of abnormal cells in the mucous membranes

Treatment of mucosal irritation

The treatment of mucosal irritation depends on the cause and severity of the irritation. In some cases, a simple home remedy such as a saline solution to rinse the nose or eyes may be sufficient. In other cases, medical treatment may be required, such as

  • Antihistamines or steroids to relieve allergy symptoms
  • Antibiotics, antivirals or antifungals to fight infections
  • Painkillers or anti-inflammatories to reduce swelling and discomfort
  • Surgical procedures to remove foreign bodies, ulcers or tumors
