It is common for puppies to be more active and energetic at night, especially if they have not had enough physical and mental stimulation during the day. Puppies have a lot of energy and need regular exercise and mental stimulation to stay healthy and happy. Without enough of these, they may become restless and hyperactive at night.

There are several things that you can do to help your puppy settle down at night and get a good night’s sleep:

1. Provide enough exercise and mental stimulation during the day: Puppies need plenty of exercise and mental stimulation to tire them out and keep them happy. Make sure that your puppy gets enough physical activity during the day, such as walks, runs, and playtime. You should also provide your puppy with plenty of mental stimulation, such as training sessions, interactive toys, and puzzle toys.
2. Establish a consistent bedtime routine: Establishing a consistent bedtime routine can help your puppy wind down and get ready for bed. This could include a final potty break, a quiet activity such as reading or brushing, and a comfortable place to sleep.
3. Create a calm, quiet sleep environment: Your puppy’s sleep environment should be calm, quiet, and comfortable. Keep the bedroom dark and cool, and remove any distractions that could disrupt your puppy’s sleep, such as loud noises or bright lights.
4. Avoid giving your puppy too much food or water before bedtime: Overfeeding your puppy or giving them too much water before bedtime can lead to discomfort and the need to use the bathroom during the night.
5. Ignore undesirable behavior: If your puppy is acting hyperactive or restless at night, it is important to ignore the behavior and not reward it with attention. Giving your puppy attention when they are acting hyperactive or restless can reinforce the behavior and make it more likely to continue.

If your puppy’s hyperactivity at night persists despite trying these strategies, it is important to see a veterinarian to rule out any medical issues that could be causing the behavior.

In conclusion, puppies may become hyperactive at night if they have not had enough physical and mental stimulation during the day. To help your puppy settle down at night and get a good night’s sleep, it is important to provide enough exercise and mental stimulation during the day, establish a consistent bedtime routine, create a calm, quiet sleep environment, avoid overfeeding or giving too much water before bedtime, and ignore undesirable behavior. If your puppy’s hyperactivity at night persists despite trying these strategies, it is important to see a veterinarian to rule out any medical issues.
