Here is a comparison to the girl pup you saw. My leggy awkward girl at five month bday and closer to six month bday - now with about 3 inches on belly. Both my dogs are closely related, and both were identical as teens: awkward, lanky, sleek, skinny. Fingers crossed she turns out like he did. I drool for your guys coat and his ears seem to want to tip naturally!
btw this brown girl is supposed to be the aoac I had hopes for! Even went to a breeder who usually has aoac, sure that is what I would end up with! Instead, she happened to breed a half sister (maternal) to the half brother (paternal) with my original breeder who moved out of state. No inbreeding, separate lines, even though it sounds like it. My boy has as much gene pool in common as a parent, just divided differently. Makes me laugh, four generations in my family of brown dogs- 100 years. I swear my next one will be aoac. I would love a tri or biblack or blue once in my lifetime! I hope you post pics often.
