Vaginitis is a common condition that affects female dogs, and it refers to the inflammation of the vagina. This condition can occur in dogs of any age whether spayed or intact, but it is more commonly seen in puppies and older dogs.  

There are two types of vaginitis: juvenile or puppy and adult-onset vaginitis. Juvenile vaginitis occurs in puppies between the ages of six months and two years. It is usually not a very serious medical condition and heals on its own after a female puppy’s first estrus, also known as dog heat cycle

On the other hand, adult-onset vaginitis can occur at any age. The condition is usually not serious, but it can cause discomfort and can lead to more serious complications if left untreated.

Vaginitis in dogs can have several causes, including bacterial infections, fungal infections, hormonal imbalances, and foreign bodies. Bacterial infections are the most common cause and are often the result of the normal bacteria found in a dog’s feces migrating to the vagina.  

Fungal infections, such as yeast infections, can also cause vaginitis. Hormonal imbalances, particularly an increase in estrogen levels, can lead to vaginitis in adult dogs. Lastly, foreign bodies, such as grass seeds or other debris, can cause irritation and inflammation of the vagina.

The symptoms of vaginitis in dogs can vary depending on the severity of the condition. Some common symptoms include: 

  • Discharge: Dogs with vaginitis may have a cloudy or white vaginal discharge. The discharge may have a foul odor and can be more noticeable after urination.

  • Redness and swelling: The vaginal area may appear red and swollen. Your dog may lick or scratch at the area due to discomfort. 

If you notice any of these symptoms in your dog, it is important to consult with your veterinarian for a proper diagnosis and treatment.

  • Urinary tract infections (UTIs): The inflammation and irritation caused by vaginitis can increase the risk of developing a UTI. UTIs can cause more severe symptoms and may require additional treatment. 
  • Chronic vaginitis: In some cases, vaginitis can become a chronic condition, leading to recurrent infections and ongoing discomfort for your dog.
