If your dog has a brain tumor, you may notice symptoms such as energy loss, loss of coordination, and weakness. Brain cancer is a common condition in older dogs. If you discover these or some other symptoms of a brain tumor in your pet, take him to the vet immediately for an evaluation.
Clinical signs of a brain tumor include:
- Variable behavior
- Decreased cognitive function
- hearing loss
- Abnormal pupil size
- Acute seizures
- Constantly panting or abnormal
- Inability to walk
- Spin in one direction
Diagnosis of a brain tumor
Diagnosis of a brain tumor in dogs usually begins with a thorough physical examination by the veterinarian (including a careful neurological examination to look at the pupils, response to light, reactions in the extremities, etc.). Additional tests for diagnosing a brain tumor include:
- Essential blood works to ensure that the kidneys, liver, and other organs are functioning properly and assess white and red blood cells
- X-ray on the chest to ensure that obvious cancer does not spread to the lungs
- Computerized tomography or magnetic resonance imaging under general anesthesia to look specifically at the central nervous system
Types of brain tumors
There are different types of brain tumors in dogs. Meningiomas are the most common type of brain tumor. These tumors begin at the covering membrane of the brain – meninges. Meningiomas tend to expand slowly. They generally respond to treatment.
Choroid plexus papillomas, gliomas, adenomas, and pituitary tumors are all cancers in dogs. Choroid plexus papillomas are usually located in the fourth ventricles of dogs. Glioma descends from the supportive tissues of the dog’s brains. Adenomas are generally found in the anterior and canine sinuses of the dogs. Pituitary tumors in the pituitary glands are located in the posterior sections of the fangs of the brains.
Brain tumors are believed to be more prevalent in canines than other types of domestic pets. Fangs 5 years or more are more susceptible to brain tumors than their younger counterparts. Dogs of some breeds are particularly vulnerable to certain brain tumors.
Dogs from vertical muscle strains are more likely to develop pituitary tumors. Small-headed dogs – bikinis, French dogs and bulldogs are all examples – they notice their flat faces and their small, short noses.
Dolichocephalic strains, on the other hand, are more likely to develop meningiomas. Dolichocephalic dogs – German Shepherds, Cole and Greyhounds examples – have long masks, in stark contrast to the biceps.
Brain tumors, in general, are particularly numerous in Labrador apostates, golden retrievers, Boston terriers, pins, Doberman pins, English bulldogs, Old English Shepherd dogs, Scottish dogs, boxers and mixed breeds. Both male and female dogs appear to be affected equally.
Symptoms of brain tumors in dogs vary. They differ depending on their exact size and location in the brain. Some appear quickly and seem out of nothing, while others are more progressive in their presentation. Some of the common symptoms of brain tumors in fangs are head tilt, head rotation, vision problems, blindness, walking problems, confusion, increased pain sensitivity on the neck, reduced coordination, decreased appetite, nose bleeding, circulation, sneezing, difficulty breathing, panting and aggressive behavior other than Habitual, depression and atypical eye reactions.
Seizures, however, are the most common sign of brain tumors in canines. If your dog has seizures that started after the age of five, brain tumors may be the cause.
If you notice any signs of an EEG in your dog, contact your vet immediately to make an appointment. Most brain tumors in dogs cannot be cured. However, it can be addressed in general.
Dogs whose brain tumors are not diagnosed early often live for short periods of time. However, appropriate treatment can sometimes take a few years over the life of the affected dog. Treatment options for dogs with brain tumors include radiation therapy, surgical extraction, chemotherapy, and palliative care. Palliative therapy focuses on relieving symptoms and suffering rather than treating the actual condition.
Brain tumor treatment
Emergency treatment of brain tumors is often necessary – because dogs often have secondary acute episodes of brain tumors. Unfortunately, slow-growing brain tumors may exceed the normal area of the brain. When the tumor gets older, it can cause pressure changes within the brain (for example, cerebral edema), which leads to neurological signs.
