I have very limited time and patience and money for vet or doctor bills, so I try to run a pretty tight ship 'round here....
I stop dogs at the door, when dropping out of the truck, etc. Truck has a wonderful aluminum 2 hole dog box with slider vents that can be opened or closed depending on the weather. Drop chains are used on the truck to keep them put for their business while on the road. If we're in the Pathfinder they're in crates. Sometimes I let Dulcie ride up front, but these days I'll put her harness on and run the seatbelt through the back of it.
Dogs loose in the wide world for any length of time get e-collars on. I've lost years off my life as it is watching them dart out to chase something in front of logging trucks on dirt roads.
I just built the Ultramax Dog Containment Facility last summer, complete with hot wire around the bottom and at the top. Nobody is going under or over it... but then I also have a pigeon coop in there which keeps everyone quite entertained inside. If I drop them loose out of the truck at home, they make a beeline for the yard gate.
Crates are in the back utility room, which can be doored and gated off from the rest of the house. Daughter has been taught to LEAVE US ALONE when I'm feeding. We've trained the dogs to tolerate us messing with their food dish, but i'm not pressing my luck and she should steer clear of other people's dogs eating from a bowl anyway. OTOH I bring her in to give each crated dog a cookie now and then- she loves it and so do they obviously.
Dogs are taught to put up with us futzing with feet, eyes, ears, mouth, etc. so they're ready to go to the vet and get the best care possible when they need it without undue hassle or sedation. All the mushing stuff I do keeps them socialized them pretty well- they've been around strange people, dogs, bikes, cars, motorcyles, snowmobiles, giant trail groomers, even headed nonchalantly into helecopter prop wash once. At this point in life they're like "strange situation number 3,852....whatever".
