With my old dog I only trusted 1 kid to walk him. She was in an abusive enviroment & her dogs were too old & sick to be walked far. We knew it would help her if she walked him & it did. She would even babysit him for a weekend or a week & sleep on our couch so he wouldn't be alone. She was also safe from her father when she was at our place & with Max. So we saw her a lot until she was old enough to move out on her own.

When Max was 6months old, we took him on a family trip to PEI. Next to our camper & tents was an old camper & 2 young teen girls (if they were even 13). My dad saw them pouting & pacing about for a few hours & he couldn't stand it anymore. He invited them over to play with our puppy. Then he asked them to take him for a walk around the campground. It was 6pm when they returned with him (we could see them the whole time) & their parents still didn't return. So we invited them for dinner & they stayed until very late as their folks still hadn't returned.

So ya, it really depends on the kids & the dog.
