Being tiny puppies you can't expect them to just understand that they can't just take a treat out of your hand, jump all over you or bite you until you give in however you can teach this to them.
We took a handful of treats and held them in a closed hand, the puppies then tried to break in by licking, pawing, biting etc the second they backed off we took a treat from the closed hand and fed them from the other hand a short way away from the body to teach them they can be rewarded away from our bodies as well as up close which will come in handy when they're a bit older.
As we went along we asked for more and more from the puppies, going from a momentary movement away to the puppies stepping away, making eye contact with us, sitting and walking away.
We also managed to get to the point with some of them that we could keep the hand open with the treats in clear view, something that is quite complex and many adult dogs are not capable of.
Unfortunately we didn't get any of this on video however this shows exactly what we did.
Claire was really impressed with how bright these puppies are and how quickly they picked up on this. She also managed to get a video of the puppies manding, something I've not managed to do!
