Digital Radiology

Equine DVM, Inc has offered portable digital radiographs (xrays) since 2006. Now, in 2013 we have upgraded to wireless digital radiology. One exciting benefit of this transition is that there are no wires connecting the various components of the system. This improvement in technology allows pictures to be taken in more positions more easily. There are no more wires to get tangled or limit maneuverability around a horse. In addition, this new equipment is powerful enough to image adult equine spines, skulls, stifles and shoulders. On farm thoracic imaging is also possible.

Portable digital radiographs expedite on farm shoeing and dental consults and allow immediate diagnostics and prepurchase examination results. Most important, horse owners and trainers can see the xray images at the time of the examination and discuss the diagnosis and prognosis with Dr. Harris. This benefit of streamlined communication allows treatment options to be selected quickly or purchase decisions to be made at the time of the prepurchase examination.

Equine Dentistry

Equine DVM, Inc. does not offer primary care equine dentistry. Instead we have chosen to support Arizona registered, certified equine dentists. In Arizona, equine dentists can only practice under the supervision of a licensed Arizona veterinarian. Equine dentists, when properly trained and certified, are an indispensable resource. Quality dental maintenance improves health and function for all horses. Performance, halter and residential horses all benefit from routine, ongoing, professional dental care.

Although we support all Arizona registered, certified equine dentists, the equine dentist whom we utilize most often is Chip Sarchett, CEqD. The office at Equine DVM, Inc. is happy to schedule dual appointments with Dr. Harris and Chip, or the Arizona registered dentist of your choice, whenever necessary. For routine equine healthcare we recommend having Chip scheduled in conjunction with your spring or fall vaccinations.

The word euthanasia is derived from the Greek words eu- and thanatos (death). The literal translation is ?easy death?. While there is much controversy surrounding ?mercy killing? or euthanasia of terminal human patients, in veterinary medicine the humane destruction of animals that are suffering is expected. The American Association of Equine Practitioners has gone so far as to publish guidelines for euthanasia to which veterinarians are ethically bound.
[ Read more about the guidlines. ]

While it is difficult to choose a day for an elective euthanasia; when an animal is suffering, or no longer enjoying or prospering in their life, Dr. Harris believes that it is a privilege to provide them with an end of life transition that allows dignity and comfort.

There are a variety of options available from Equine DVM, Inc. We provide in home or in office euthanasia services for small animals. Cremation is available with or without return of ashes.

Horses and other large animals are usually euthanized at home and their remains can then be removed immediately for burial or cremation.

Please do not hesitate to call the office to schedule a consultation with Dr. Harris or to make end of life arrangements for your animal. We try to be immediately responsive to your needs when such important decisions are required.

Llamas & Alpacas

Llamas and alpacas are camelids, relatives of the camel. They are hornless, hooved animals native to South America. Both species originated in the Andes Mountains at high altitude in a temperate to cold climate. When kept in Arizona care must be take to control their environment during the summer months as heat stress can be fatal. Both species are also very susceptible to Valley Fever which is difficult to treat in camelids.

Dr. Harris is available for routine health care of llamas and alpacas: vaccination, deworming and hoof trimming. She has also had some success treating Valley Fever using intravenous fluconazole.

Pot-Bellied Pigs

Vietnamese Pot-bellied pigs were first brought to the United States from Vietnam in the mid 1980?s. With these pigs came a great deal of misinformation about adult size, life span and behavior. Not for every pet owner, pigs are intelligent and opinionated; but for those who love them they dedicated, loyal family members.

Vietnamese Pot-bellied pigs reach maturity at four to five and usually live for fourteen or fifteen years, with some individuals reaching the age of twenty. Mature body weight should be between 130 and 150 pounds ? heavier with improper or unrestricted diets. Around 2005, breeders began producing miniature pot-bellied pigs that were developed to be about one fourth the average size of the original Vietnamese Pot-bellied pigs. It is too soon to know what an average life span of one of these individuals will be.

Dr. Harris began treating Vietnamese Pot-bellied pigs in the mid-1990s when they became extremely popular nationwide as pets. These original animals have passed away now, but the truly dedicated pig owners have repopulated and vaccinations, hoof trims and spay and neuter surgeries are still available from Equine DVM, Inc.

Prepurchase Examination

Equine DVM, Inc. offers several types or levels of equine prepurchase examination in an effort to meet the needs of the prospective owners of many different types of horses. Dr Harris believes that prepurchase examinations should reflect the intended use of the horse, the age and previous use of the horse, and the experience level and financial risk being taken by the prospective buyer.

Every prepurchase examination begins with a thorough physical examination of the horse at rest and in motion. Additional diagnostics are then added to the program depending on the intended use for the horse and the concerns of the buyer or their agent. Examples of additional diagnostics would include ultrasound examination of the reproductive organs of a potential broodmare or radiographic evaluation of the legs of a performance horse. Genetic evaluation is available for many of the heritable disorders of horses. Baseline blood values for health and thyroid function may be indicated. In some cases drug screens are done to evaluate chemical enhancement of performance. And, a Coggins test for equine infectious anemia should be considered if a horse has not been tested for over a year.

Dr. Harris believes it is extremely important that the veterinarian and the potential buyer, or their agent, communicate clearly before, during and after a prepurchase examination.

Respiratory illnesses are the predominant medical complaint and C-sections top the surgical charts.

Equine DVM, Inc. has invested in a camera manufactured by FLIR, an industry leader in the field of thermography. A thermography camera detects differences in temperature across the surface of objects placed in front of it.

When a horse is examined using a thermography camera warmer surfaces are interpreted as areas of increased circulation and cooler areas as having less functional vasculature. Some differences in temperatures between body surface areas are expected. The hoof wall has less vasculature than the muzzle and should be cooler in a normal horse. On the other hand, symmetrical body parts should be similar in surface temperature. For example, the anterior surface temperature of a horse?s right knee should be very similar to the anterior surface temperature of the left knee on the same horse.

By comparing symmetrical body parts on the same horse, while taking into account normal body surface temperature variations, Dr. Harris can identify areas of abnormally increased or decreased body surface temperature. These quantifiable observations can then be extrapolated to identify areas of abnormally increased circulation (inflammation) or areas of decreased vascularity (devitalized tissue). Once areas of abnormally increased or decreased circulation are identified other diagnostics, such as ultrasound examination, can be used to identify the underlying pathology in the region pinpointed by abnormal body surface temperature.


Wellness Management

Wellness management is the veterinary component of equine farm management. Equine DVM, Inc. offers comprehensive evaluation of farm preventative medicine practices and nutrition counseling. Dr. Harris enjoys tailoring vaccination and deworming schedules to meet the unique needs of your farm. She will take into consideration the demographics of your farm population, your competition and travel schedule, and the various components of the diet you are feeding.

Please contact the office to schedule a Wellness Management consultation. (602 494 9669) These consultations are available as a courtesy to Equine DVM, Inc. clients.
