LAVA is a full service ambulatory practice providing over 50 years of combined veterinary experience. While each veterinarian at LAVA is competent in all aspects of large animal care, they each have specific areas of interest. This allows for a more well rounded practice and better care for your equine companions. We feel that the most important service we offer is “Service Itself”. We strive to have helpful caring staff members anxious to answer all your questions and concerns. Our doctors are kind, caring, approachable and accessible. A doctor is always on call to provide after hours care and consultation when needed.

Dart Guns

LAVA is equipped with two types of dart guns for sedating horses that are wild, loose or fractious. This equipment has been vital over the years with wild horses in the farthest corners of East County, assisting the San Diego Humane Society with loose, unrestrainable horses and with the occasional horse person that has adopted a wild horse or burro.

Prepurchase Exam

While the process of purchasing a new equine companion is a joyful and exciting time, it is often a time of stress and uncertainty. Our goal at LAVA is to provide you, the buyer, with the most in-depth evaluation possible. We strive to acquire all the necessary objective information we can to help you make an educated decision on the purchase of your next companion or performance horse. We consult with you regarding the results of the exam and the anticipated intended use of the horse being evaluated. Several prepurchase exam options are offered to help meet the unique needs of every prospective buyer. Depending on the situation and the intended use of the horse, numerous additional tests and procedures are available as add on services for the exam including survey radiographs and ultrasound imaging, laboratory panels and drug testing. The doctors at LAVA are versed with all riding disciplines and breeds of horses including gaited horses to provide you with the most thorough exam possible.
