Bringing a new puppy home is full of exciting milestones—those first tail wags, playful zoomies, and sleepy cuddles. But just when you think you’ve established a consistent sleep schedule, something changes. Suddenly, your four-month-old pup starts waking up at night, crying in the crate, or refusing naps. Sound familiar? You might be dealing with puppy sleep regression at 4 months.
This stage is common and can be confusing for many dog owners. Understanding what causes it and how to handle it can make this temporary phase smoother for both you and your pup.
What Is Puppy Sleep Regression?
Sleep regression is a temporary disruption in your puppy’s sleep routine. Your puppy may have been sleeping through the night or taking predictable naps during the day, and then out of nowhere, they start waking up more frequently, resisting sleep, or becoming more restless.
Just like human babies, puppies go through developmental changes that affect their sleep. Puppy sleep regression at 4 months is one of the most common phases, often tied to growth, teething, increased energy, or behavioral shifts.
Why Does Sleep Regression Happen at 4 Months?
There are several reasons why sleep may become inconsistent at this age:
- Teething Pain
At around 4 months, many puppies begin losing their baby teeth and growing adult ones. Teething can cause discomfort, which may make your pup more restless at night or irritable during nap times. - Developmental Milestones
This age is when your puppy becomes more alert and aware of their environment. They’re learning new behaviors, absorbing new commands, and growing mentally. All of this cognitive development can make it harder for them to wind down and rest. - Increased Physical Energy
As your puppy grows, so does their stamina. They need more physical and mental stimulation to burn off energy, or they may resist naps and have disrupted nighttime sleep. - Changes in Routine
Any change in feeding time, walk schedule, or crate training can affect your puppy’s internal clock. Puppies thrive on routine, so even small disruptions can lead to sleep regression. - Fear Periods or Anxiety
Around four months, some puppies go through what trainers call a “fear period,” where they become more sensitive to sounds or changes in the environment. Anxiety can make it harder for them to settle down for sleep.
Signs of Sleep Regression
If you suspect your puppy is going through sleep regression, look for these common signs:
- Waking up multiple times during the night
- Whining, barking, or crying when crated
- Skipping naps or resisting bedtime
- Increased clinginess or anxiety
- Sudden reappearance of bathroom accidents at night
How Long Does Puppy Sleep Regression Last?
Fortunately, puppy sleep regression at 4 months is temporary. It typically lasts anywhere from a few days to a couple of weeks. The duration depends on your puppy’s breed, temperament, and how you manage their routine during this time.
How to Handle Puppy Sleep Regression
While this phase can be frustrating, patience and consistency go a long way. Here are a few tips to help your puppy (and you) get better sleep:
- Stick to a Sleep Schedule
Maintain consistent wake, meal, play, and bedtime routines. Predictability helps your puppy feel secure and teaches their body when it’s time to rest. - Increase Daytime Activity
Add an extra walk, introduce new puzzle toys, or extend playtime to ensure your pup is tired enough to sleep. A mentally and physically stimulated puppy is more likely to nap and sleep well at night. - Create a Comfortable Sleep Space
Ensure your puppy’s crate or bed is cozy and located in a quiet, low-stress area. You can also use white noise machines or calming music to promote relaxation. - Soothe Teething Pain
Offer safe chew toys, cold carrots, or frozen washcloths to ease teething discomfort before bedtime. This can reduce nighttime restlessness. - Minimize Middle-of-the-Night Interactions
If your puppy wakes up crying, give them a few moments to settle before rushing to their side. If a bathroom break is necessary, keep the interaction calm and brief—don’t turn it into playtime. - Stay Calm and Positive
Avoid punishing or scolding your puppy for waking up. They’re not doing it on purpose, and negative reactions can increase anxiety. Positive reinforcement and patience will help them transition back to regular sleep. - Consult Your Vet if Needed
If your puppy’s sleep issues persist beyond two weeks or are accompanied by health symptoms like vomiting, diarrhea, or excessive discomfort, it’s wise to check with your vet to rule out any medical issues.
Final Thoughts
Puppy sleep regression at 4 months may catch you off guard, especially if your pup had been sleeping well. But remember—it’s a normal part of their growth and development. Just like every other phase of puppyhood, this too shall pass. By staying consistent, offering comfort, and gently reinforcing healthy sleep habits, your puppy will get back on track—and so will you.
Let this be a time of learning and bonding, not stress. A little extra patience today means a happier, well-rested pup tomorrow. Petsdogpuppy
