The sequence at 0:39 is really nice, working on those at source alerts.
The sequence around 1:30- you can see the truffle fly out behind him and he does a great job of realizing it?s no longer there and it just then becomes another search around the area which is tough, but you do a good job. This is super realistic and so you know that if he?s not staying at source like that (after that very very clear initial alert), that it likely has been tossed from the hole and so you can help him look a bit for it. Once you direct him a little he has a much easier time of locating it and offers that really nice lie down.
Well done working it out.
Over all, good. That went really well I think.
