What a little beautiy she is, our first pup Rocky was a collie/shepherd mix and he had the same 1 straight ear and 1 lop ear and he was the best, neatest dog. He loved everybody and was very sociable with other animals. We had 3 cats when we got him and he never messed with them, he had total respect. Wishing you so many happy, healthy years with little Miss Lucy. Please give her a couple of Milk Bones from Gracie and Jake.
