Well done Barnaby!
It's great when they start to learn tricks, makes you wonder why they can't pick up the easy stuff like walking nicely on the lead.
Jmmy is the trickster in our house, Misty tends to be a bit over eager. She can do roll over but usually gets too excited and messes up..... I've been trying to get a formation roll over going with Jimmy but no success yet. He's usually on his third roll before I can get her to lie down.
He used to be good at balancing a treat on his nose then flicking it up and catching it. We can't do that anymore as Misty steals the treat off his nose pre flick, much to Jimmy's annoyance.
