This is our Chihuahua/Boston Terrier mix (Bo-Chi) named Shep! He was a rescue that we adopted from the Humane Society. We had never seen the two breeds mixed before but thought it would be perfect because he is tiny and hypoallergenic like a Chihuahua but quite and obedient like the Boston, and he's absolutely adorable too!! Bo-Chis, in my opinion, are by far the cutest hybrid breed!
