Carcinomas are a type of cancer that starts in the skin or the inner lining of the body. They can develop anywhere in the body, but they most often occur in the mouth, nose, and anus.
Carcinomas in dogs are rare and typically develop as a result of another condition. In some cases, there is no known cause for carcinoma development.
In general, dogs with this type of cancer are between 6 months and 8 years old. However, it can affect any dog regardless of age or breed. The most common signs include:
- Lumps on your dog’s skin
- Swelling around your dog’s eyes
- Your dog is breathing heavily
- Your dog has difficulty eating or swallowing
