I also remember once when someone had the baby in his lap and when she heard a noise and jumped for it, they let her. I always stop her and let her down. They said, 'she wanted to go'. Of course, we have hard floors, too. I prefer they not jump from couch level when excited.
In 7 years with 6 pups, we have had two escapes. Once, two got out, a woman opened her car door - Trina jumped in, Quattro ran home. She followed Quattro and returned Trina. They are very fast and we never let them out without a leash. We count them constantly (easy as they are almost always underfoot
. Many years ago, I had a little guy who snuck out in the snow. A neighbor found him and took him in. She saw us out looking for him and ran out. I thought he would have surely died.
Anyway, our pups don't usually like strangers to hold them, but in these unusual situations, I guess they felt they needed help. ??
