Dr. Wheeler from Palm Beach Equine Clinic helps explain the pre-purchase exam.
No matter what the breed or discipline, pre-purchase exams include several initial steps. First, an overall health evaluation of the horse is completed, and often includes previous health history, general condition, and conformation, as well as specific examination of the body systems including eyes, cardiovascular system, and respiratory system.
Next, a lameness assessment is completed, including flexion tests, soft tissue structure palpation, and movement evaluation. Additional diagnostic imaging such as radiographs (x-rays), ultrasound, endoscopy, magnetic resonance imaging (MRI), nuclear scintigraphy (bone scans), or computed tomography (CT) scans may be requested to provide more information.
Why perform a pre-purchase exam? To assess the overall current state of health and soundness at the time of the examination, as well as gather information that may help to predict the level of risk as it pertains to the future use of the horse.
“The first thing I do is talk to the potential buyer and trainer to understand their expectations and any concerns that have arisen during the trial of the horse. Next I discuss the horse with the current owner and/or trainer to determine what level of training or competition it is in, and if it has any previous issues that they are dealing with,” said PEC veterinarian, Dr. Wheeler.
“Then we look at the horse in a static exam in the stall. We do a physical exam, looking at the whole body from front to back. Key points are the eyes, heart, and lungs and we palpate from the head and neck, to the back, and down the limbs. We are looking for signs of old injuries or areas that may have issues; conformation comes into play here as well.”
“We want to look at the horse in a dynamic exam. We usually look at it on the lead line and on a lunge line, or trotting in a circle on hard and soft surfaces, and then also under saddle. I like to see all of my horses go under saddle because we can observe the interaction of horse and rider, which is very important. During this stage we will perform flexion tests and ask the horse to perform specific movements depending on the discipline.”
“Blood tests are often taken and normally will include CBC, chemistry, Coggins test, and a drug screen. Depending of the age or type of horse other tests may be performed.”
“Finally, there are some auxiliary tests, which may include radiographs, ultrasound exams, and endoscopy of the upper airways. These days, if there are certain issues, we will also include further diagnostic tests such as MRIs, CT scans, or bone scans. That depends on what is found in other parts of the exam. If there is something suspicious on a radiograph, the buyer might want to do more advanced imaging. Or sometimes, depending on the value of the horse, they might want to do that anyway.”
Dr. Wheeler pointed out that a pre-purchase exam is not intended to recommend the horse for purchase or for sale. The exam is performed to provide information about the level of risk and to educate the client about that risk.
Every exam is different, but the basic steps of evaluating a horse for any discipline or level of competition are fairly standard. It is important to have a veterinarian who is experienced and knowledgeable about the specific discipline to provide accurate guidance on the horse’s condition for the expected job.
