I have just found a dog in my yard. I cannot decide if it is a min pin or a chihuaha. Could someone help me? We are putting up missing dog signs but if no one claims him I would like to know what it is because we are going to keep him. So could someone explain the physical difference to me?
Min Pin: Alert appearance. Larger size than a Chihuahua, longer thinner head shape, square build, straight, short back. Tail usually docked in the US, ears sometimes cropped. Ultra-high energy, bouncy, and independent. http://www.akc.org/breeds/miniature_pinscher/
Chihuahua: Small (under 6 pounds), rounder head shape, longer body, tail never docked, ears never cropped. http://www.akc.org/breeds/chihuahua/
