Oh, yeah. Got lots.
My wife - not a small woman, not a light woman, with 5 knee surgeries under her belt, wants a large dog. Great Pyrenees/Black Lab. Some kind of mountain dog cross. Finds it, fights a guerrilla war to get her way. Kids whine, she whines, "Fine! I don't care, I'm not taking care of it, and I'm not picking up it's poop!"
Drive to the farm. 2 1/2 hours each way. Let the kids pick; they pick the biggest by about a 1/2", the only one to run up to them and jump up on them and play with them.
Pay the bill. Thank GOD I'm driving. Dog Freaks out, jumps out of my wife's lap in a moving vehicle, nose in the kid's faces, tail whacking the backs of the front bucket seats and our arms, barking like its seeing the only home its ever seen vanish and throwing giant wads of spittle everywhere.
I actually had to pull over, put the leash back on, and block it in. Too bad the trunk was full, because 5 minutes later the floor was wet. Then, he puked. And he barked and whined all the way home.
Finally get home. Open the doors, kids jump out, drag the dog on the leash. BAAADD IDEA. Dog takes off, looking for home, dragging two of them, tree saved them from getting to the sidewalk. Shoulder-checks the wife across the knees. She's down for the count, swearing.
I finally get over there, grab the leash. Damn dog puts up a good fight but I sit on him, then lift him up and carry his squirming ass into the house.
And that is how it became, 'Your dog.' Lucky me.
Incidentally, it turns out the farmer lied to my wife, or just made a mistake. Its not a Pyrenees/lab mix; its a spitting image of a Great DANE/Black Lab. 130 lbs, 1 meter tall (about 36 1/2") on all fours.
