From Gutsoon!:

Yashiro Animal Hospital is a little bit different from other animal hospitals in that the doctor has an animal counseling center where animals can walk in and pour their hearts out to him. How is this possible? Doctor Yashiro understands animal talk! Amazingly, this incredible gift was passed down to his son, Tasuke, who is not really excited about his newfound abilities. When he falls head over heels for Funakoshi Misato, Tasuke decides to adopt her pet dog, Wata. Unfortunately for Tasuke, Wata is a dog that will bite anyone but her master Misato.
