Large Animal Preventative Care

 Large Animal Internal and General Medicine

Because of our doctors’ diverse backgrounds, our veterinary staff has extensive experience diagnosing and treating a wide variety of injuries, diseases, colics and other conditions in our large animal patients.  With a collective thirst for knowledge, our doctors and staff routinely seek continuing education in order to remain at the forefront of large animal veterinary medicine.


Equine Dentistry is critical for horses’ eating and performance.  Since all horses develop sharp enamel points that may interfere with proper eating, Allen Animal Clinic provides sedated oral exams, dental and floating services both in our large animal facility and on farm calls.

How often do I need to float my horse’s teeth?

In general, equine teeth should be floated to remove any sharp points and checked for any oral abnormalities once a year for horses between 6 and 20 years of age.  Horses under 6 or over 20 years old should be checked every six months.

Eye Care – Ophthalmology

Eye injuries and eye disease are common in horses and other large animals and are critical to treat quickly.  We see animals in our office or ambulatory for eye medicine and surgery.  Specialty appointments or consultations with board certified ophthalmologists are also available as needed.

We examine horses for a range of ocular disorders including eye injuries, corneal ulcerations, uveitis, cataracts, etc.


Lameness in horses can be a serious medical condition.  Allen Animal Clinic evaluates lameness through physical examination and flexions with diagnostic aids such as analgesia (blocking), and digital X-Rays

Horse Microchip Identification

A microchip is a small, rice sized object that is gently inserted into the left side of the neck of our horse and can be detected with a standard scanning device most veterinarians’ posses.  Allen Animal Clinic uses the DATAMARS Chip that is in accordance with ISO standards 11784/5 (required by the FEI and recognized by USEF) which is an international recognized chip.
