What is border collie?
The border collie is a working breed of dog that was developed in the Anglo-Scottish border region. It's usually used for herding livestock, like sheep.
I like dogs
I like dogs too. Somtimes I like to watch those agility competitions, like the Fisbee Dog World Championship.
Really? I would watch too
Yeah, they're a lot of fun. There are major competitions held all over the world.
Please mention some 
There was one that I watched this summer - the Purina Pro Challenge. My favorite part was when they threw a toy into the water, and the dogs had to jump to get it. The dog who jumped the furthest and caught the toy successfully was the winner.
