Is Chino a mini or small standard?

Chino was rescued and will be 2 on February 15. I’ve had standards and they were much bigger in the 60-70lb range. He weighs 48 pounds and is 17” from floor to shoulder. The vet said his weight is ideal but could lose 3 pounds, lol. Just was wondering what others thought! I can’t refer to a breeder since he’s a rescue boy. 🥰
