Everything Available - Just Like a Veterinary Clinic."

Doctor Thissen is a vet specialising in small animals. In reality his practice provides a lot more. Equipped with the most modern, high quality equipment, the same service is provided which you would usually only experience in a veterinary hospital.


The high technical level is made complete with the provision of warm and comfortable surroundings. This is something which your animal also senses.
