Just because it is cold outside does not mean your dog needs less exercise. It is actually quite the opposite. There are fun games you can play with your dog inside if it is too cold for outside games. Make this 15-30 min of family fun. If you have stairs in your home have one person on the upper floor and another person on the lower floor, start the dog on one floor and the other family member calls the dog to the next floor. This way the dog is running up and down the stairs and getting some good exercise. This is also a good way to help reinforce puppy commands such as come, touch or fetch if this game is played with a toy being thrown up and down the stairs. Keep the family together!
