Proper AH Trick for Watch Dog

[Byronus]

I wanted my Ranger character to have a dog as a pet (non-Animal Companion) to watch over the adventuring party as they rested. The dog would hang out downwind of the camp and Perceive any enemies downwind from it, using it's Scent ability, as well as sight and hearing, to detect enemies approaching the encampment from that angle. Once detected, it would bark to warn it's master. An extra set of eyes never hurt, right?

I'm not sure what Trick would apply. I want the dog to Seek out threats, but to Stay stationary, so those two Tricks seem to make the most sense. But aren't those two actions covered in the Guard Trick? The wording of Guard seems to imply that animals with that Trick will put themselves in harm's way when performing that function. I don't want the dog in danger; I just want to be warned of possible danger.

So, which is it? Guard, or Seek+Stay?

It's also called rolling perception. What you are looking for is Watch (DC 15): The animal can be commanded to keep watch over a particular area, such as a campsite, and raise an alarm if it notices any sizable or dangerous creature entering the area. This trick is often included in the Guarding purpose.

Yes, I understand it involves the Perception skill. That's why I capitalized "Perceive" on the OP. :)

I'm playing Core-only PFS. I take it the Watch option isn't available to me, then.

Thanks for the prompt reply.

I discovered the Watch Trick, among other Tricks, on d20pfsrd.com. What is their source?
