Client Feedback

Having in the past had vets who had very poor communication skills and getting information was like pulling teeth! We now have vets who have very good people skills, they give information freely and keep us informed at all times. We have an excellent relationship with all of our vets, this comes when your practice is not too big and your customers have names not numbers. We are very grateful we made the move to The Cow Vets.
