Yeah I'm familiar to that, my dog Laïka ran away when she got the chance, got hit by a car, first time she'd run away.
She got 10 months old and I still see her laying in the sofa while I'm blasting Best of You from the Foo Fighters when I was home alone, now we got Sandy, but she likes to lay on the ground, due Laïkas accident I'm muuuuuuch closer to Sandy. we got Sandy just 2 days after Laïka because the house was just tooooooo empty and we all couldn't live with that.
