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?
Different sizes, head shape and body structure, along with totally different personality traits.
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/
