Who is the most gentle caring Vet in Plano or Allen Texas?

I have a large lab mix that has been my baby for a few years. Although he is loved and doted on now, our precious pup was abused when he was young. He's not aggressive, but very scared and passive. It's imperative that we find a Vet that is gentle, loving, and empathetic to him. We have just moved to the East Plano area and would like to know who you would recommend in the Plano, Allen, area.
