Bella and I have been training HER. Every night Bella goes into the garden, finds a frog and harrasses it until it makes a high-pitched, clicking sound. (She hates that.) When I hear the sound I run and stare at HER.....sometimes giving my attention growl. Now Bella can only be enticed away from the frog with a treat. So SHE starts yellin', "Wanna a treat? (or cheese)" Bella leaves the frog and we all get a treat while she shuts the door. Took awhile, but SHE's finally got it!
