Sounds like Zoe had tons of herding instinct! The first thing Logan will do upon meeting anyone is smell their shoes and ankles. I took her out of the car at the train station the other day while waiting for John and asked everyone in advance if she could do her thing. Everyone loved it and petted her. I'm the only person who's shoes (heels) she'll actually grab when I'm in the yard with her. I know she's playing hard. She's never bitten. But if she gets over zealous, I clap my hands hard and firmly say NO. If she gets goofy in the house, I threaten or grab the soda can full of pennies and she stops instantly. I agree, I wouldn't let the kids walk her until she's trained not to do that.
