Hello and welcome here are some tips and tricks -Always let the dog choose what to play by laying out the toys and letting the dog choose -when the dog won't fetch any more give him some water and let him cool down until he's ready to play again

Pups need lots of play time so make sure to play with them. Even if it means swimming or playing fetch. When your dog pants give him a water break. Then go back to playing. When your done for the day pet him and praise him because he is just the best.
