Quinto our cutie :)
That pic looks very similar to the pup we adopted from the shelter. We were told he was a border collie chihuahua mix. But as he ages, he shows traits of being a Jack Russell (facial whiskers, hind legs, jumping) with some chi features (pointy ears, thin tail, small stature). He could be a tri-mix but so far, none of the border traits are coming through at all. :( We still love and adore him but we were so used to the innate obedience and eager to please nature of a border that this JRT is a challenge. Headstrong and stubborn--but ADORABLE!
