Canine chronic ulcerative stomatitis (CCUS) is a painful condition characterized by inflammation and ulceration of the oral mucosa in dogs. This condition can significantly impact a dog’s quality of life, leading to discomfort during eating and other activities.

What causes CCUS?

This is an oral inflammatory condition in dogs. The exact cause remains unknown, but it is believed to be an immune-mediated disease where the dog’s immune system overreacts to the bacteria in plaque. It is possible that chronic oral inflammation can play a role in the development of CCUS.

What are the symptoms of CCUS?

– Ulcers and Lesions: Open sores are commonly seen on the gums, tongue, and inner cheeks (mucosa).

– Painful Mouth: Dogs may exhibit signs of pain, such as whining, pawing at the mouth, or reluctance to eat.

– Bad Breath

– Excessive Drooling: Increased salivation can occur as a response to oral pain and inflammation.

– Difficulty Eating: Affected dogs may chew less or refuse food altogether due to severe oral pain.

Diagnosis of CCUS:

– Oral Examination

– Dental X-rays

– Biopsy and Histopathology

Treatment of CCUS:

1.) Oral Surgery: In most cases, full mouth dental extraction is required for management of CCUS.

2.) Medications:

– Anti-inflammatory medications and pain relief can help manage pain and inflammation. (Carprofen or Rimady)

– Antibiotics (Doxycycline)

3.) Aggressive Dental Care: In some mild cases of CCUS, regular cleanings performed under general anesthesia paired with daily teeth brushing at home can be an effective management strategy.
