I put mine in the car, drive maybe 3/8 mi & presto! they're out. That has been ok until last fall when we had an "crusty" encounter with a hunter. And he's there nearly every am of the fall season which is problematic, to say the least. Otherwise, no one usually around - but when they do see people, they take to running up & that makes some people nervous which is fair enough, Labs notwithstanding. Was running in Concord, MA maybe 25 yrs ago, crossing a field, knew it was private & a mean Doberman came at me threateningly, closeby - no stick, no tree, nothing. Was truly concerned but then the owner called him off. "Speak softly but carry a big stick" is not a bad plan for strange dog encounters.
I put my dogs in the car and drive 10 miles, and Piper, the younger dog is still barking a mile a minute with her nose pressed up against the passenger side windshield looking for all the world like a rabid animal. And when we are going for a run (made obvious by the choice of car in which I transport them), Fonzie joins in the cacophony as well, although not in quite so frenzied a manner.
On the other hand, despite their behavior in the car, the dogs are generally quite well behaved in the woods. Although we do meet quite a few people in the woods we frequent, most of them are also there with unleashed dogs, so for the most part they have been very understanding. There was one incident several years ago when Fonzie did inflict a wound on another dog, although both the other owner and I did not notice any particular aggression. It almost seemed that the other dog had snagged a skin flap in the groin on Fonzies teeth as they ran past each other. (Yes, I know this sounds like a rationalization, but nevertheless it was my perspective.) In any case, we exchanged information and I paid for the visit to the vet for suturing, and we had subsequent friendly encounters in the woods, so I don't really think there was any resentment over the event.
Drive 10 mi (ea way?)- maybe you should move to Weston, they still have trees there.
We once had Ernst Linder's dog, Yaena, here for a week; she was tolerated. Sometime later at an O meet, our dogs pounced on her, bit her lip which bled but it healed w/o sutures. Silly creatures. Mocha's favorite move is to roll on dead, sinking stuff - can see the wet-like hair, keep the nose away, ask the wife to clean it off....
Actually, I only drive 1.5 miles to either Powisett or the Needham TF, but I do take the dogs 10 miles frequently (to Weston in fact) to visit my parents. It is not a sufficiently long time for Piper to calm down. That normally happens after about 30 min into a trip. She is really quite a handful in the car.
