I am disappointed we have no houndsmen on here. It is two Beagles doing what they do...chasing rabbits. my guess is that that it kept moving in a circle behind you? Rabbits are like most other animals, they will always end up back where they started unless they hole up.
Thats exactly what it sounds like to me too.
Had rabbit beagles my whole life. Nothing more fun that a good rabbit hunt.

Sounds like a juevenile Sasquatch to me, i would contact the guys at the BFRO, (Bigfoot Field Research Org.) and get them out there ASAP to investigate.
