The dogs worked together. First they ran after the ball, biting at it and driving it this way and that, but soon after, they learned that it was doing no good so they shifted to me and Todd. Oxie, a robust Australian Shepherd, led the other two. When she switched to people, the two heelers switches as well. It didn't take but a few minutes to gain results.
Todd was running pretty fast when the dogs came swooping in at him. Okie went at an angle toward him. I started yelling for him to run faster which he did, but to no avail the dog hit him hard, he tried to turn but she got his knee (drew a little blood), but she hit him with such force that he was knocked off balance for just a second. That's all it took for Dakato to leap in from the front angle, grabbing his shirt tail and swinging him even more off balance, and that's when the Cheyenne smashed into him (I honestly can't remember where) and he went down like a ton of bricks. The dogs scattered, barking like mad, because it was such fun.
Todd was cussing up a storm.
It was funny as hell, but gave me a real good idea of what dogs can do to prey. I'd know this I suppose through watching documentaries and what not, but until you see it played out on a human, it doesn't seem that bad.
Its really the way the trip ability should be used. Each successive hit requires the player to make a check. If they fail, they fall. The CL should be raised by at least 1 for each wolf/dog that hits the character, and maybe even by the wolf's hit dice.
These guys are apex predators for a reason.
Here's an interesting video on wolves and their impact on the environment.
