Rattlesnake Ranch - dog training area

What do they train the dogs for? I assuming something with rattlesnakes?

@MonkeyBat Yes, they train dogs in rattlesnake avoidance.

This place trains between 2,000 and 3,000 dogs per year, which is an extraordinary amount. Even the owners have been surprised at how popular their business has become, which in turn funds the Rattlesnake Ranch zoo with its 100+ rattlesnake exhibits.
