The nerve center of veterinary innovation for dogs, cats, and pets of all kinds.

Neurology is the study of the nervous system, which includes the brain, spinal cord, nerves, and the junctions between nerves and muscles. Disorders of the nervous system can be very complex, with subtle signs, and frequently require specialized diagnostic procedures and advanced imaging to diagnose.

Veterinary neurologists use highly specialized equipment to diagnose and treat conditions affecting the nervous system of pets, including retrieving cerebrospinal fluid with a “spinal tap,” and electrical testing of nerves and the nerve-muscle junction. Advanced imaging studies (CT scans and MRIs) of the brain and spinal cords complete the arsenal.

Introducing ASG’s nationally recognized Team Neuro.

Treatment may vary from medication for pets with seizure disorders to actual brain surgery. Our board-certified neurologist and board-certified surgeons, expertly trained in the latest advancements in neurosurgery, make up the ASG Neurology Department (‘Team Neuro’). They offer a full range of surgical procedures to help get your pet back on his or her feet. Whether repairing herniated discs, removing brain tumors or correcting congenital anomalies, it is truly amazing what modern surgery can accomplish, and what conditions are now treatable.

Internal medicine specialists receive specialized training in diseases that affect the entire body, but there are groups of internists that seek out even more highly focused training, including cardiologists, oncologists, and neurologists. There are only 184 board-certified neurologists in the country, and most of those teach in veterinary schools. We are fortunate to have our very own board-certified neurologist, Dr. Sullivan, on staff and under our roof. She works closely with our oncology, radiology, and surgery departments to offer a full range of diagnostic and therapeutic procedures for our patients.

Making sense of seizures in pets.

We know just how terrifying those 30-45 second seizures are. Time stops as you become helpless, and 30 seconds seems like 10 minutes. You’re not alone – everyone feels that way during the first few (or the first few dozen). Rest assured that we understand, and we’re here to help.

While the most common cause of seizures is epilepsy, it’s not the only cause. Examination of cerebrospinal fluid (CSF) and advanced imaging studies may be necessary to rule out other potential causes. The treatment of epilepsy, just like other conditions, depends on the individual. Some pets do not require medication, but many do. While traditional anticonvulsants work well in many pets, newer medications may be more appropriate. We work with you and your family veterinarian to determine the best course of therapy.

Helping paralyzed pets regain a quality of life worth living.
If you woke up and couldn’t feel or move your legs, “frightened” would be an understatement! As a pet parent, you’d feel the same way if your pet couldn’t walk, or feel his/her legs. Paralysis occurs for a variety of reasons – rest assured that we are here to help diagnose and treat your pet’s condition. Many paralyzed pets can be given the ability to walk again with the appropriate surgical intervention.

Managing the toughest cases requires the most experienced Doctors.
Neurology cases require the most experienced and steady of healing hands. Team Neuro has more than 100 combined years of practice. Whether it is encephalitis, epilepsy, a spinal disorder, head trauma, a brain tumor or neuromuscular disease, our neurology team will do everything in its power to see your little loved one through this delicate time.

Frequently Asked Questions

A veterinarian who has been awarded this specialty status by the ACVIM will list the initials, 'DACVIM (Neurology),' after his or her veterinary degree. Or, the veterinarian may indicate that he or she is a 'Diplomate' of the ACVIM. The word 'Diplomate' typically means the specialist has achieved the following:  

Obtained a traditional 8 year veterinary degree (four years of college plus four years of veterinary school).

Completed a one year internship and an additional two to three years of advanced training, including a residency at an approved program where the doctor will have trained with some of the best experts in the field and obtained hands on experience.

Following this training, the aspiring veterinary neurologist must pass a series of examinations covering all aspects of general internal medicine and neurology.

After completing and passing all of these rigorous requirements, the veterinarian is then recognized by his or her peers as a board certified specialist in veterinary neurology. Many veterinary neurologists are also trained in neurosurgery, while others limit their practice to the medical aspects of the discipline and work with a surgeon on the cases requiring surgery. When your pet needs the care of a veterinary neurologist, years of intensive training and additional education will be focused on helping him or her to recover from his or her problem or enjoy the highest quality of life possible.

In some cases, your veterinarian may be able to simply consult with the veterinary neurologist about your pet's care. In other cases, it is necessary to actually refer you to the specialist. Veterinary neurologists are trained in state of the art diagnostic techniques and will utilize advanced imaging such as CT or MRI scans to look at the structures of the nervous system. With electrodiagnostic tests, a neurologist can examine the function of the peripheral nervous system, particularly the nerves and muscles. Spinal fluid analysis can provide clues to such infectious diseases as encephalitis or meningitis. Veterinary neurologists also will be able to make appropriate recommendations for your pet's rehabilitation period, especially after such major procedures as back surgery. Lengthy recuperation times can be necessary, and your pet may be referred to rehabilitation facilities offering such services as water or physical therapy. Pain management will also be addressed.

Neurological examinations typically proceed from head to tail, with all areas of the body being given systematic attention in that order. In addition, your pet may be videotaped for future reference and to help train other veterinarians.

Mental status: The pet will be observed to determine whether it interacts normally with its owner, other people and animals, and the environment.

Gait and body posture: The veterinary neurologist will watch the animal walk around the room, in the hallway, or up and down stairs. Additionally, the neurologist will make observations regarding the animal's body posture.

Cranial nerve examination: The pet's senses of sight, smell, and hearing will be checked, as well as its ability to chew, swallow, and move its tongue, eye, and facial structures normally. Response to pain will also be checked.

Physical examination: The pet's body will be palpated for any signs of pain or muscle atrophy. The veterinary neurologist will also perform a number of tests with the pet's limbs to check reflexes and reactions, such as turning a pet's paw over to see if the pet will reposition it to the normal stance, and lifting a pet up off the ground and lowering it back down to see how it positions its legs upon contact with the ground.

Reflex testing: Just as in humans, a veterinary neurologist may check a pet's reflexes as part of the examination process.

Complete loss of function of any or all limbs
Recurrent or intractable pain, specifically of the back and neck
Head trauma
Spinal trauma
Severe depression or inability of the patient to respond to its environment

Depending on the source, the incidence of epilepsy among the general pet population is estimated at between 0.5 and 2.3%. Epilepsy refers to chronic, recurrent seizures and can be inherited or acquired. Thus, epilepsy is a clinical condition, not a specific disease. Idiopathic epilepsy refers to recurrent seizures in which no identifiable cause is found to explain the seizures, such as metabolic disease, toxin exposure, encephalitis, or brain tumors. Seizure diagnosis involves ruling out common causes of seizures. Initially, your veterinary neurologist will likely order a series of blood tests to help rule out metabolic and toxic causes of seizures. Depending on the age of your pet, the course of the seizures, and the results of the neurological examination, the neurologist may recommend an MRI or CT scan of the brain and/or a spinal fluid tap to look for signs of encephalitis or brain cancer.

Idiopathic epilepsy is most common in purebred dogs, with an age of onset between one and five years of age (often before three years). Dogs and cats with idiopathic epilepsy are completely normal between seizures and have a normal neurological examination.

If your pet's first seizure occurs before 1 year of age or after 5 years of age, is not normal between seizures, or if there are any abnormalities on neurological examination, the veterinary neurologist may recommend advanced diagnostics, such as an MRI of the brain, to help determine the cause of the seizure

Myelogram: Contrast dye radiographic study of the spine.

CSF tap: Cerebral spinal fluid removed from the spinal cord and analyzed.

Electromyography: Electrical impulses are used to diagnose the function of nerves and muscles.

Imaging techniques such as MRI and CT.


Veterinary neurology is a challenging field in that some diseases are solely neurologic in origin while in other cases, the neurologic problem may be related to an underlying systemic disease. In the first case, the veterinary neurologist may be able to treat the neurologic problem directly. In the second case, resolution of the neurologic problem may hinge on the correct diagnosis and treatment of the underlying disease. For example, certain viral infections may result in neurologic signs.
