Due to the high frequency of cancer cases amongst older animals, tumors in dogs are a relatively common occurrence. While some tumors are malignant and develop as a result of cancer, others are benign and pose little immediate threat to your pet's livelihood. In any case, a tumor is a serious health concern and is one that should be addressed as quickly as possible.
If you detect a tumor anywhere on your dog's body, take him to a veterinarian for prompt examination and diagnosis in order to determine the best course of action to take. Although they are not the most common tumors in most dog breeds, nasal tumors can cause a number of different symptoms, regardless of whether they are malignant or benign. Watch out for the following primary signs of nasal tumors in dogs.
Abnormal Growths
The leading warning sign that your pet is suffering from a nasal tumor is the presence of an unusual lump or growth on his nose or in his nasal passageways. These growths are seldom detectable through sight alone, although they may be visible in certain cases. Generally, however, you may only notice the presence of a lump or other growth by feeling your pet's nose. When you are cleaning your dog or brushing his teeth, gently feel his nose for any signs of unusual growths that may indicate tumors. It is best to conduct a test of this kind about once per month, as testing too frequently can make an abnormal growth difficult to detect on touch alone.
Unusual Bleeding or Discharge
Dogs with nasal tumors typically experience one or more types of nasal discharge. Generally, this consists of either blood or mucous, and the discharge itself may occur frequently or only semi-regularly. If your pet appears to have fluid of any kind coming out of his nostrils or above his mouth, keep a close eye on him. If the discharge continues for more than a few hours, take him to a veterinarian for further examination and testing.
Breathing Difficulties
Dogs with nasal tumors occasional suffer from difficulty breathing. A nasal tumor that is lodged lower in the nasal passageways may partially constrict the air supply that your dog can take in as he breathes. This may lead to a wheezing sound while he breathes, or to a rough cough that occurs periodically. Take note also if your pet appears to tire or have difficulty breathing after a short period of physical activity.
Change in Appetite
In some cases, a nasal tumor can affect a dog's appetite. If the tumor is located in particular areas within the nasal passages, it may cause your dog pain or discomfort as he attempts to chew or swallow his food. If you notice that he appears to have lost his appetite or to have left some of his food untouched, take him to a veterinarian for further diagnosis.
This list of potential nasal tumor symptoms is not exhaustive. As a general rule, it is best to be cautious when dealing with matters regarding your pet's health. If you are at all concerned by any unusual behavior or physical sign that your pet displays, have a veterinarian examine your dog in order to determine that his health is not at risk.
