  • "Doc Villa ALWAYS takes care of Studly Dudley!! I will ALWAYS recommend Callahan Drive Animal Hospital & their entire team as they truly do care for your animal in the same way you do!! Dr Villa has cared for Dudley for most of his SIXTEEN years & he’s still happy, healthy & strong!! I strongly believe, Stud has made it to this old age so gracefully due to the care he’s been given with this facility!! I would not trust another team than Callahan Animal with my “first child”, the only place for us to go!! Highly recommended!!"
