Labs never seem to wear out when playing ball or swimming. A lab pup needs lots of running and playing outside. Some "doggy cookies" will wind them up also. Full tummies will make them sleepy. Our pups thought that "flip flops" made great chew toys. Ya just got to make sure that they understand the word "NO". A rolled up newspaper slapped across your hand and a firm "NO" always works well. Keep all door's closed to all the room's you don't want her in. All our dogs had a "toy box" and 2 of them even learned they had to put their toys back in toy box when not playing with them. Callie....not so much. All dogs are different. Callie will chase the ball but will not bring it back. She is not a retriever but a Leonbuger, a little nuts at times, a German breed.
