Oh my goodness! They are all just to cute to try and choose from! I personally like Lark, Quail, Grouse, and Gull. If you can't decide exactly which one you want, I would do this. Narrow it down to the 2 or 3 that you like best and when you go to pick the pup up, put the three together in a spot with you and let the pup choose you. Just a thought.
I would go with either Wren, Quail or Robin. Of the three of these I would probably pick Robin. THey are a medium to long coated breed, so you will have to brush them out, a good job to teach the kids!
But I agree, when you go to pick it up, take the three aside from the others and see which one seems to fit the best. Let the pup decide.
