Ellie is an active 1 to 2 years Sheltie mix and weights about 20 pounds. She was very scared the first week at my home. I let her decide when she was ready to come to me and by the end of the second week, she opened up and would let me pick her up. Now she is a happy playful girl, who some times gets into things. She likes Itze (Chihuahua/Jack Russell) the best of all the dogs and he tolerates her and even like to play. She will try to herd Itze sometimes, which is fun to watch.
