Thank you for your reply, Labman!
Yes, I was thinking a slip collar was cloth and metal chain collar was called a "choke" chain, but not synonomous terms. Thanks for the information.
What I'm finding with my pups (both 7 mos.) is that when at Petco or out and around, they don't pay attention to me but rather are distracted; going off to do their own thing and when I've stopped walking will circle me. It's been years since I've had a puppy and taken a training class. It's becoming obvious I need to go back for a refresher.
This is the greatest site for helping a very rusty puppy owner and a huge thanks to all who are participating!
