Gus is our second dog--he is a short haired tricolored Border Collie. Like Ivy, he is also trained on sheep and can take both voice and whistle commands. He is an avid swimmer, following the geese immediately into the water if need be.
Ivy is our first highly trained Border Collie. She is extensively trained on sheep, as well as geese. This allows her to take flanking commands, going to the left or right, and to be able to be called off of whatever she is doing instantly if the need arises. She responds to both whistle and voice commands. Border Collies trained in this manner are safer to use in areas where there is traffic. In addition, they never revert to just chasing the geese, which can endanger the geese or nearby ducks. Ivy stalks her geese, rather than chases them. She has two degrees, an MBA and a Phd, from Pupperdine University. (Master of Bird Aggravation, Pretty hardworking
