I feel horrible, even 5 years after I let my wifes dog out the front door and he ran straightinto the road and a truck hit him right in front of us. She cried for days and to this day I feel like a piece of crap forthat.She wasso attached to that dog too.
I now have a 4 year old chocolate lab, he's great! We call him our son becausewe do not have kids. But one thing I learned from past dogs getting run over is build them a pen, a big pen. If you build them a big pen, they will not try to dig out either. I use 5 ft. wire, 4" x 2" squares. Build it big, like an acre or even more. Its several hundred dollars up front but its a good investment. When I walk out my back door, I step right into my dogs pen. I know he could die of something in the future but it sure as heck won't be from a car.
Your new pup will be a great companion, like all labs
