About Bluestack Veterinary Clinic

Bluestack Veterinary Clinic has been the dream of John and Kathryn for many years. They have always wanted to establish a family run mixed practice with traditional values. They hope to deliver personal, compassionate and quality veterinary care, tailored to the needs of every client.

The surgery in Donegal town is state of the art and purpose built. It has all the modern equipment needed for practicing veterinary medicine to an extremely high standard. We have two consulting rooms, full surgical suite, digital radiography, ultrasonography, dentistry equipment, in-house blood machines and a full laboratory.

After the success in Donegal Town, Kathryn and John opened a branch practice in Ballybofey in January 2024. This practice is situated on the outskirts of Ballybofey town. The practice is well equipped with a range of equipment such as digital radiography, a dental machine, ultrasonography and surgical theatre.

The Veterinary Surgeons alternates between both practices, catering for all of our client’s needs, including our small animal, farm and equine patients.
