Recognizing the symptoms and signs of Brain Tumors in dogs is the first step to knowing that your dog may require medical attention. Because diseases and symptoms can vary from dog to dog, it’s always best to consult your veterinarian if you notice any of the following symptoms.
How Brain Tumors Affect Dogs
It is hard to say, generally or specifically, how brain tumors affect any given animal. The symptoms that they experience will depend upon the location of the mass, its size and its aggressiveness. Certainly, depending upon those things, dogs may experience any range of effects, from none to extreme pain and distress. Unfortunately, the outcome for a dog with either a benign or a malignant brain tumor is not all that different in most cases… The effects of the tumor are caused by the space-occupying mass, no matter where it comes from.
Symptoms of Brain Tumors
Brain tumors, depending upon their location, size, aggressiveness and type, can cause any number of clinical signs in dogs and in other mammals. These can come on slowly (be insidious) or come on suddenly (acutely). They may include:
- Seizures (seizures are the most commonly recognized sign of brain tumors in dogs, especially after they reach 5 years of age)
- Blindness or vision deficits
- Abnormal ocular (eye) reflexes
- Head rotation
- Head tilt
- Abnormal behavior and mentation, especially unusual aggression
- Lack of coordination (ataxia)
- Abnormal gait
- Abnormal stance
- Lack of appetite (inappetence; anorexia)
- Nose bleeds (epistaxis)
- Difficulty breathing (dyspnea)
- Panting (open mouth breathing)
While there are no definitively identified causes of brain tumors in dogs.
