whippet?
Think about a whippet too if you want it to run in a sport, but not for money. I don't know how the "bussiness" of racing is in Aussie but its detestable here and I wouldn't own a dog so it could participate in that kind of life.
I know labs and German Shorhairs love to swim but what other breeds love the water? I'm a big swimmer, floater, fisher and need a water dog. Does anyone have a Austalian Cattle that loves the water?? Is it common for them?
