Willows are the youngest ones but you can't tell - can you? When they are around older pups they usually meet the challenge and learn from the older crew. It's amazing how much they progress with older pups around.
To me, it's as if they are all the same age. Of course Tempie's are starting to depart on Friday. Will they notice? I bet they will. We shall see.
Videos coming ah I got to do that. :-)
