Getting a good night sleep with a new puppy in the house can be difficult. The biggest thing that can help is to maintain a routine for sleep, play and eating. Make sure your pupgets plenty of exercise and frequently opportunities to eliminate.
Play time should be at least 2 hours before the designated "sleep" time. Ensure you have plenty of toys and know the types of games your dog likes best. Play for at least 30 minutes each day.
