Dog Nasal Cancer Symptoms

Updated February 21, 2017

Nasal cancer comprises only one per cent of cancers in dogs, according to Vet Surgery Central Inc. However, if your dog presents any of the symptoms associated with nasal tumours or cancer, it can be worrisome. As soon as you notice symptoms, is important to take your pet to a veterinarian to be checked out.

Nasal Problems

Dogs suffering from nasal cancer typically have a host of symptoms that revolve around the nose. These include nasal bleeding, sneezing and nasal discharge. The discharge may appear yellowish, white or green in colour. According to the Pet Cancer Center, these symptoms usually last at least three months on average before a diagnosis is made. These symptoms also may be indicative of a fungal infection rather than nasal cancer.

Facial Problems

Although the cancer may be located in the nasal passages, other portions of a dog's face may be affected. One symptom of nasal cancer is a facial deformity. This may occur due to the erosion of the bones because of a tumour growth in the facial area. Dogs also may experience eye discharge and obstructions that affect the ducts. This can in turn cause breathing difficulties for your pet.

Other Symptoms

Although nasal cancer in dogs tends to isolate itself in the nasal passages, it may eventually spread to other parts of the dog's body. When this occurs, the dog may present additional symptoms. According to Vet Surgery Central Inc, one study showed fewer than 12 per cent of cases involved the spreading of the disease when the cancer was first diagnosed. However, in dogs that had died from the disease, 46 per cent had evidence that the cancer had spread to other areas such as the lungs and lymph nodes. If the cancer has not been treated, other symptoms could include difficulty breathing, loss of energy and loss of appetite.

A Veterinarian's Diagnosis

Although most symptoms are visible to the eye, your veterinarian will likely look at other ways to diagnose your pet. These include running blood work, taking chest X-rays and ordering CAT scans. Your vet may order a biopsy if he finds a growth inside the nasal passages.
