Breed guesses are just for fun, we'll probably never know, JRT has been my guess on this one. And I do think they have difference sires. The other puppy from this litter (and no, I have no clue what the mom looked like). In odd ball tail, originally I thought it looked kind of like a boston terrier tail, but about half of it curls down, and the other have goes into a point and doesn't have a bone in that part, just weird. Only pup in the litter w/ it. Only short haired pup to (all with similar coloring though, must have gotten that from mom).
As for ear plugs, these girls are currently super quiet, haven't even heard them bark yet, do think I heard one howling the other day though.
