Search for the perfect Dog Trail…Trail 1

I am on a mission for the perfect dog hike for my three yahoo's...Kobe, Lucy & Sunshine.  This is not an easy task! I need a place I can have my dogs off a leash, preferably West of Bozeman (I live at Four Corners), would love Mountain scenery, and preferably no construction workers!

Trail #1 took me to the Middle Creek Subdivision.  This one is within a mile of my home, so it's super convenient.  Although the subdivision is in it's initial building stages, they have put a nice trail in already that spans the subdivision and loops back to where you park.  The best part of this hike by far is the views, it's basically like walking through an open field.  The distance of the loop is probably about 2 miles, so it's perfect for an "every day" type of walk.  The really negative point with this trail at this time is the construction workers.  Currently there are a dozen homes being worked on, so it's a busy place to be.  Overall I like this trail and will use it for quick walks, but not it's just not quite what I am looking for.  The search continuese!
