The Ishihara Animal Clinic is owned by Dr. Ishihara, and located close to the houses of Sakaki and Chiyo. According to a sign outside the building, the clinic is open from 9:30 to 11:00 A.M. and 1:30 to 7:00 P.M. It is closed on Saturdays, Sundays, Thursdays and holidays.
Chiyo has been taking Tadakichi-san to the veterinary clinic for a long time, and says it is thanks to Dr. Ishihara that her dog is always so healthy. During Chiyo's third year of high school, though, Dr. Ishihara gets another client – Maya, the cat that Sakaki befriended on Okinawa that travelled all the way to the mainland so he could see Sakaki after his mother had died in a car accident. Ishihara examines Maya and to the girls' happiness, announces that the cat is alright.
The only known staff members of Ishihara's animal clinic are Dr. Ishihara himself and a female receptionist and/or nurse who meets Sakaki and Chiyo-chan when they come to the clinic with Maya.
