Possible symptoms of a dog brain tumor range from imperceptible to extreme.
Tumors may develop in any part of the brain, with symptoms evident over time or abruptly.
As the person who knows your dog the best, you are likely to be the first one to notice any physical and psychological changes signaling a brain tumor.
Both malignant and non-malignant tumors pose a threat, so it is important for you to know how to recognize symptoms, no matter how subtle.
The sooner treatment begins, the better chance your dog has for survival.

Physical Symptoms of a Dog Brain Tumor

Signs a tumor may be impairing your dog's motor skills and bodily functioning are:

Changes in gait, including a slower walk
Falls due to loss of balance
Difficulty jumping and climbing
Loss of senses, including sight and smell
Hypersensitivity to touch
Difficulty moving the eyes
Reduced appetite
Difficulty swallowing
Excessive thirst
Weakness on one side of the body
Facial paralysis
Head tilting
Pressing the face against a hard surface

Psychological Symptoms of a Dog Brain Tumor

Signs a tumor may be compromising your dog's mental functioning and mental health are:

Personality reversal-for example, docile dogs becoming aggressive and aggressive dogs becoming docile
Compulsions, including eating and barking
Disorientation, including an inability to recognize your voice or find the way home
Your dog may also communicate the extreme discomfort and distress caused by a brain tumor by whimpering, whining and whelping.
The presence of one or more symptoms of a dog brain tumor necessitates prompt evaluation by a vet. Treatments include surgery, chemotherapy and radiation. Such options can be highly effective, but extremely expensive.

Diagnosing a Brain Tumor in Dogs

A brain tumor in dogs are difficult to diagnose because the symptoms can be attributed to many different things and often go unnoticed. However, brain tumors are very serious, and a dog may only have a few months to live without treatment.
Thus, proper diagnosis at the earliest stage is critical.

Brain Tumor Symptoms

Depending on the location of the tumor on the brain, your dog may not show symptoms right away.
When the tumor is small, the body can adjust to the changes, but when the tumor gets too large, your dog will start to show symptoms.

Occasionally the symptoms will be obvious, such as seizures or blindness, but often the symptoms are just a change in intelligence or behavior.

If the tumor is located on the forebrain, you may see behavioral changes, increased or decreased appetite or thirst, decreasing vision and seizures.
If it is located on the brain stem, you may see leaning and falling, a drunken gait, circling, loss of appetite, a head tilt or abnormal eye positioning.
If it's located on the cerebellum, you may see an uncoordinated gait, swaying, a wide stance, head tremors or head tilt.

Brain Tumor Diagnosis

Before beginning any expensive procedures, your vet will try to rule out other options through complete blood testing, urinalysis and a complete physical and neurological exam.
Since many of the symptoms of brain tumors can appear with other illnesses as well, it's important to determine definitively if your dog has any of these other illnesses.

After other options are eliminated, your dog will have to get an MRI scan or a CT scan, which will identify any unusual lumps in the brain. MRIs show the brain in more detail than CT scans, but the tests aren't as widely available and cost more when they are.
Tissues from any abnormalities will be removed through a biopsy and studied in the lab since masses caused by infections can mimic brain tumors but be relatively harmless.
Studying the tissue will also help identify if the tumor is malignant.

Brain Tumor Treatment

Since many pet owners opt not to treat brain tumors, little is known about the effectiveness of treatment.
Tumors can be surgically removed, depending on their location, or be treated with chemotherapy and radiation.
If the dog is showing secondary symptoms, such as seizures, those also may be treated to improve the dog's quality of life.

Treatment does appear to increase the lifespan of dogs with brain tumors.
Those showing less symptoms or with smaller tumors have better chance for success.
Tumors of the forebrain are easier to treat than tumors of the brain stem and cerebellum.

If you notice a sudden behavior change in your dog, especially if he is older than 5, consult your veterinarian before calling a trainer. Usually sudden behavior changes in older dogs are related to health problems.
Since brain tumors are so difficult to detect, take action as soon as possible.

Dog Brain Tumor Treatment Options

A dog brain tumor is a serious yet often treatable medical condition often seen as part of dog cancer.
Dog surgery, while often necessary, is not the only option for treatment.
The treatment options may vary depending on whether the tumor is primary versus secondary, benign versus malignant although the basic four treatment options usually remain the same in treating dog cancer.

Categories of Treatment: Curative & Palliative

Treatment of a dog brain tumor falls into one of two categories. Curative treatment either seeks to eradicate the tumor or reduce its size.
Palliative therapy reduces seeks to slow the growth of the tumor by reducing the surrounding brain edema or swelling.
If seizures result from the brain tumor, palliative therapy includes antiepileptic drugs.

Dog Surgery

Several factors will determine whether or not surgery is the best treatment option for a dog brain tumor.
The veterinarian will consider the precise type, size, location, invasiveness, and nature of the tumor as well as the general health of the animal.
The goal of surgical removal of a brain tumor is either or to alleviate the clinical signs by decompressing the brain or to cure the disease by complete removal.
Dog surgery rarely cures the disease, but removing the dog brain tumor can be life saving if it is very large.
This can be life saving if the mass is very large.
A tumor in certain locations of the brain such as the brainstem can be extremely dangerous and possibly fatal to remove.
Some veterinary surgeons may then opt to remove only part of the tumor which can still greatly benefit the animal.

Radiation Therapy

Clinical and scientific research on dog brain tumors has established radiation therapy as a widely accepted treatment option.
The goal is to destroy the tumor with minimal damage to the normal tissue.
Veterinarians often employ radiation therapy on its own or in combination with other treatments, and it is effective on many types of tumors.
General anesthesia is usually required for treatment.
Radiation can be given on different schedules depending on the nature of the tumor.
In some cases, the vet may recommend daily or every other day treatments.
Radiation therapy may prove effective when given only once a month.


Little information is available to support or deny the effectiveness of chemotherapy on dog brain tumors and dog cancer.
Very few chemotherapy drugs can cross the blood brain barrier but some recent advances in human brain cancer research may eventually penetrate the world of dog cancer treatment.
Some tumors are only affected by high doses of chemotherapy which may then prove toxic to animals.

Palliative Treatment

The pet owner may opt to treat the symptoms caused by a dog brain tumor.
Palliative treatment is a good choice when all other therapies are no longer an option or the dog is suffering from the results of the tumor. Palliative treatment usually addresses seizures and brain swelling. Dogs can usually tolerate an anti-seizure drug such as Phenobarbital or potassium bromide.
A corticosteroid such as prednisone can treat brain edema or swelling. Some animals show a marked decrease in symptoms from brain edema in as little as 24 hours after the drug is administered even if the effects last only temporarily.

While a dog brain tumor is a serious issue, it does not have to mean an imminent death sentence for your dog.
Some tumors can be cured and most can be treated to give your dog a bit more quality time with you

It is so true about brain tumors. Our Fur sis was a very calm 14 year old Cardigan Corgi. She had a large fatty tumor removed from her leg. All went well then she was this different doggie, running around, playing more. Mum thought she was happy to be more mobile. Then a few weeks later she had one seizures after another. Our vet said she had a brain tumor and might of had it for a while, and the operation she had for her leg might of progress it faster....
Please Please if any fur shows any type of a different personality please have them looked at...
I missed my Jezebell so much..cry
