Laser Therapy

How do lasers work?

The laser system sends photons, or packets of light energy, deep into tissue without damaging it. These photons are absorbed within the mitochondria of the cells and induce a chemical change called "photo-bio-modulation." This light energy then inspires production of ATP in the cell, which is fuel needed for cell repair.

What can be treated?

The laser is used to treat a variety of injuries, wounds, fractures, neurological conditions, numerous dermatological problems, and pain.  The laser provides relief and speeds healing. 

How long does the treatment take?

Treatment protocols are unique to each patient and condition. Treatments will vary on the individual. 

When will I see improvement?

It depends on the condition. You may see relief after the first treatment.

Laser Rental Program

One laser is specifically designed for use by you!  Multiple treatments are needed initially and then can be tapered off. Laser protocol is shown in a demonstrations then a treatment protocol is designed specifically for your animal. The laser is designed to be used for horses, dogs, and cats.

 It can be rented weekly for a fee.  There is a special introductory fee for this laser, but it will only be going on for a few months! 

Please call or email for details!!


Why Vaccinate?

 A “standard” vaccination program for all horses does not exist.  Each individual situation requires evaluation based on the following criteria: 

  • Risk of disease 
  • Consequences of the disease 
  • Anticipated effectiveness of the selected product
  • Potential for adverse reactions to a vaccine
  • Cost of immunization  vs. potential cost of disease

6 Core Vaccinations:


Eastern/Western Encephalitis

Tetanus Toxoid

West Nile

Rabies Virus- Exposure occurs through the bite of an infected  animal, typically a wildlife source such as raccoon, fox, skunk, or bat. Bites to horses occur most often on the muzzle, face, and lower limbs. The virus migrates via nerves to the brain where it initiates rapidly progressive, invariably fatal encephalitis. 

Eastern/ Western Equine Encephalitis Virus-Transmission of EEE/WEE/VEE is by mosquitoes, and infrequently by other bloodsucking insects, to horses from wild birds or rodents, which serve as natural reservoirs for these viruses. Human beings are also susceptible to these diseases when the virus is transmitted to them by infected mosquitoes.

Tetanus Toxoid - All horses are at risk of development of tetanus, an often fatal disease caused by a potent neurotoxin elaborated by the anaerobic, spore-forming bacterium, Clostridium tetani.   lostridium tetani organisms are present in the intestinal tract and feces of horses, other animals and humans, and are abundant as well as ubiquitous in soil. Spores of Cl. tetani survive in the environment for many years 

West Nile Virus- The virus is transmitted from birds by mosquitoes (and infrequently by other bloodsucking insects) to horses, humans and a number of other mammals. West Nile virus is transmitted by many different mosquito species and this varies geographically.  It leading cause of arbovirus encephalitis in horses and humans in the United States.

Non-Core Vaccinations 

Potomac Horse Fever


Equine Herpes(Rhinotracheitis)

Equine Influenza


Potomac Horse Fever- bacterial disease caused by the bacteria Neorickettsia risticii, which causes variable degrees of fever, lethargy, poor appetite, diarrhea, mild colic, and laminitis in horses.   The bacteria has been identified in freshwater snails, trematodes that parasitize those snails, and a variety of aquatic insects. It is not contagious.

Botulism- Botulism has been observed in horses as a result of the action of potent toxins produced by the soil-borne, spore-forming bacterium, Clostridium botulinum .  Botulinum toxin is the most potent biological toxin known and acts by blocking transmission of impulses from nerves to muscles, resulting in muscle weakness progressing to paralysis, inability to swallow, and frequently, death.  

Equine Herpes- Equine herpesvirus type 1 (EHV-1) and equine herpesvirus type 4 (EHV-4) infect the respiratory tract,  Clinical infection is characterized by fever, lethargy, anorexia, nasal discharge, cough, and mandibular lymphadenopathy.   Both EHV-1 and EHV-4 spread primarily by the respiratory route, by direct and indirect  contact with nasal secretions, and, in the case of EHV-1 and infrequently EHV-4, by contact with aborted fetuses, placental and fetal fluids, and placentae. There is no vaccine for the neurologic form of EHV-1. 

Equine Influenza-  one of the most common infectious diseases of the respiratory tract of horses.  Equine influenza is highly contagious and the virus spreads rapidly through groups of horses in aerosolized droplets dispersed by coughing. The severity of clinical signs depends on the degree of existing immunity, among other factors. 

Strangles- Streptococcus equi subspecies equi (S. equi var. equi) is the bacterium which causes this highly contagious disease.  he organism is transmitted by direct contact with infected horses or sub-clinical shedders, or indirectly by contact with water troughs, hoses, feed bunks, pastures, stalls, trailers, tack, grooming equipment, nose wipe cloths or sponges, attendants’ hands and clothing, or insects contaminated with nasal discharge or pus draining from lymph nodes of infected horses. Clinical signs may include fever ; dysphagia or anorexia; stridor; lymphadenopathy (+/- abscessation); and copious mucopurulent nasal discharge.
