The trick, so Hane discovered, is to bite the dog's feet. When the dog jumps up, he can then hop onto the bone and claim it, before the dog has the chance to grab it and run. It's worse when Tsume and Hane go at it together- doubletime!
Considering the three dogs he steals from are all over 60lbs, it is rather gutsy, lol.
Zoe has caught on, she grabs her bone before she gets up, and keeps an ear and an eye on the birds at all times.
Geronimo will nudge the birds on their back (thereby avoiding their beaks) if they're giving him a rough time, but he's a gentleman so he'll share until they get tired of his bone.
Socrates just doesn't know what to do. If he tries to nudge the birds, they bite his nose.
The small dog, Strider, chews his bones in his 'den' (crate) so the birds never bother him.
Mind you, dog saliva is bad, so the birds aren't allowed to do this when the bones are already chewed. xD
