LOL! You can buy whistles! : D
There is a really great book out there, especially for training blue heelers etc. I won't mention the author again as he has the same name as a famous porn star! Very good book though and easy to follow. : )
Sally, our Australian shelpherd, herds the 3 basset hounds we have when they are running lose! She also herds the chickens and the children! LOL
And I'll have hubby pick me up a whistle, somewhere.(heheheh)
So far, George isn't interested in the chickens. 'Course, Killer let him KNOW the 'deal'. LOL!!!
But George SURE IS fascinated by the cats/kittens.Maybe it's because they spit at him.
