The first things puppies learn is the chase me game and they find it immensely fun. It's okay for them to play it with each other and even you but they need to know the rules that you control the game.
What does that mean?
When the game is over, you shouldn't have to chase them to get them to come back in.
At first you have to learn to be creative as even 8 week old puppies will find that running to stay outside is more fun than anything else you have in mind so you may have to get them to chase you and then you stop the game by picking them up - giving them all sorts of snuggles, perhaps a treat and making the game fun to come to you.
Obedience classes are very important as you learn to get a strong recall. That's important for many reasons.
Today we had swimming, chasing, and rolling around and mucking it up fun. The pups were finding solutions on how to get from one point to the next. Find out more about their adventures at Talemaker Puppy Life.
