Peripheral nerve sheath tumors represent 25% of canine nervous system tumors and are most commonly diagnosed in middle age to older dogs. They can form in any location, from any peripheral nerve. Lesions of the peripheral nerves can be benign (schwannoma, neurofibroma), or malignant (usually a locally aggressive tumor that does not metastasize through the lymphatic system).
Tumors of the nerves are abnormal growths that originate from peripheral nerves or along the nerve sheath (myelin surrounding the nerves). In canines, the most common places a tumor of the nerves will be found are at the head and neck (cranial), the paraspinal region of the trunk (next to the spine), and the brachial plexus (a network of nerves found near the neck, shoulder and limb).Tumor of the Nerves Average Cost

Symptoms of the presence of a tumor depend on the location. Below is a list of usual symptoms:
Brachial plexus and cervical nerve roots
Lumbosacral plexus
Trigeminal nerve
You pet may also exhibit neurological symptoms that are related to spinal nerve disruption (in relation to mobility, movement and control of limbs).

While the exact cause for tumors in the nerves in dogs has not yet been pinpointed, documentation shows that the following factors have been suspected:

If you notice mobility issues, lameness, or any other sign that your dog is unwell, prompt attention by a veterinary professional is crucial. Our pets are unable to clearly express pain or illness and often try to continue on a day to day existence even though they are uncomfortable.
Schedule a visit and see the veterinarian promptly if you have concerns about a possible tumor. Documentation states that a tumor can be identified with the following elements in place:
The veterinarian will want to start with a complete physical, and at times a mass can be felt. In many instances, though, the tumor is not immediately found. The next step will be a complete blood profile, count, and chemistry.
A nerve biopsy may be suggested, as well as the tests listed below with their function:

Surgical removal of the mass is typically the treatment of choice; this decision is based on whether the tumor is accessible and can be removed in it’s entirety. Regrettably, tumors of the nerves often advance beyond surgical margins before they are identified.
Surgery, if attempted, is sometimes accompanied by hemilaminectomy. This is a procedure that removes part of the vertebra in order to relieve pressure on nerve tissue, and can also involve removal of nerve roots at the spinal cord.
Complete amputation of a limb containing a tumor is a form of treatment also, but is done specifically when veterinary surgeons feel that they can totally eradicate the mass. Radiation therapy usually accompanies the above treatment protocols.

If the tumor can be completely removed, the prognosis is much more positive. Sadly, recurrence is common, especially in cases of nerve sheath tumors in the spinal cord. Tumors in the outer locations of the nerves allow for a better prognosis than a mass in the plexus (within the network of nerves) or root.
Less success is achieved if the tumor is not completely removed, or if the neurological damage remaining is severe, which can lower the quality of life for your dog and for you as a pet owner.
It must be noted that many dogs who have tumors in the nerves face recurrence or are euthanized due to a poor prognosis of recovery. However, a benign tumor of the peripheral type (outside or in the outer locations of the nerves) can have a good chance of eradication, leading to a positive outcome. The veterinarian will be an advocate for your pet, sincerely advising you on the wisest choice for the best outcome. Veterinarian care pushes the health and comfort of your dog first and foremost, which is why it's essential to listen to the advice and medical suggestion of the veterinarian.

Thank you for your question. I find it difficult to believe that your veterinarian refused euthanasia if your dog is suffering, without knowing more about the situation. If they had a problem with it, and you feel that your dog is suffering, you will need to visit another veterinarian. It is part of our job to alleviate suffering if we aren't able to provide pain control. There may be a 24 hour or ER clinic in your area that can help you. I hope that you are able to get relief for him.

6months ago I noticed gypsy had a possible limp. I questioned it for a couple of weeks then she went for a big run one day and the limp was significant. She went on previcox but it did not help. A week later she had X-rays which showed nothing. A week after that she lost significant muscle tone in her right shoulder/biceps. She went into the specialist and he thought she had torn her bicep. Arthroscope showed nothing. Then did a CT of the neck, nothing. Then a CT of the elbow, nothing. Then a spinal tap and bloods. Nothing. A week later I took her to the vets to get some gabapentin as she was flea biting and pulling at her right leg. Three weeks later she had a review and the specialist wasn’t sure, but mentioned a possible nerve sheath tumour and sent us to a second specialist for another opinion. By this time gypsy was diagnosed with msi and underwent arthroscopy on both shoulders. She had a large tear in the right which wasn’t present a month before. She was put into hobbles and had stem cell therapy. After three months she started building up some muscle in her biceps again, but still significant wastage around her scapula and front of shoulder. She also developed a neck issue which was thought to be brought on by the positioning of the hobbles. Did an ultrasound to check on shoulder/neck and the brachial plexus looked clear. Three weeks ago she hurt her neck doing a silly movement. She went in for mri and today she has been found to have a nerve sheath tumour in her Brachial plexus now affecting multiple nerve roots. They have suggested it’s slow growing. It looks like it wouldn’t be able to be completely excised. She’s having a biopsy on Monday to try help me decide on what to do next. She is still happy, wants to play, barks at the birds. She is currently on 400mg gabapentin twice a day and 100mg previcox once a day. She seems comfortable. She still chews on her leg at times and tries to scratch her shoulder often which I believe is her nerve pain. My question is, what is the time frame if left untreated? From reading these comments it looks like amputation etc gives two years? Does that mean months if left untreated.
