Can A Puppy Go All Night Without Water? What You Need To Know

October 1, 2025 |

Keeping your puppy hydrated is essential to supporting healthy growth and giving them the best chance of a long and happy life.

Just like us, our dogs need water to help their body cells function normally. Water helps to circulate blood around the body, aiding digestion and keeping organs healthy.

Water also helps with regulating temperature – something that is super important for pups now the temperatures have risen.

As we start to enjoy the warmest days of summer, its important to consider whether your pup is drinking enough to stay hydrated.

If you notice your puppy not drinking water, dont panic! There are lots of things you can try to increase their water intake.

Ever brought home an adorable little furball and found yourself waking up to mysterious puddles in the middle of the night? Yeah, me too The question of whether puppies can go all night without water is something that keeps many new dog parents up at night – literally!

As a dog owner myself I’ve been through the struggle of balancing proper hydration with trying to avoid midnight bathroom breaks. Let’s dive into what you actually need to know about your puppy’s nighttime water needs.

The Short Answer: Yes, But It Depends

Yes, most puppies can safely go through the night without water but there are important factors to consider

  • Age matters: Puppies over 12 weeks can typically go 8 hours without water
  • Health status: Healthy puppies have different needs than sick ones
  • Individual differences: Some puppies naturally need more water than others

Understanding Your Puppy’s Hydration Needs

Puppies need proper hydration for healthy growth. Water helps with:

  • Circulating blood around the body
  • Aiding digestion
  • Keeping organs healthy
  • Regulating body temperature (super important during hot weather!)

As a general guideline, puppies need approximately 30ml (1oz) of water per 0.5kg (1lb) of body weight daily. So a 5kg puppy would need around 300ml of water each day.

But remember, this can vary based on:

  • Activity level
  • Weather conditions
  • Diet (wet food contains more moisture than dry kibble)
  • Individual metabolism

When Do Puppies Start Drinking Water?

Before we talk about overnight water restrictions, it helps to understand when puppies even start drinking water in the first place.

Puppies typically begin drinking water at around 3-4 weeks of age. This happens at the same time they start transitioning from their mother’s milk to solid food and when their teeth begin to grow.

So by the time you bring your puppy home (usually at 8 weeks or older), they’re already familiar with drinking water.

Should Puppies Have Water at Night?

Here’s where things get interesting. According to veterinary experts, unless your puppy has a medical condition, you should avoid leaving water out for them at night during the house training period.

The reasoning is simple:

  1. Most puppies over 12 weeks can go 8 hours without water
  2. Young puppies (under 12 weeks) can’t hold their bladder for very long
  3. Puppies typically need to pee within 10-30 minutes of drinking water until they’re about 9 months old

By removing water 2-3 hours before bedtime, you’re reducing the likelihood of nighttime accidents and middle-of-the-night trips outside.

Age-Based Water Guidelines

Let me break this down by age, cuz different puppies have different needs:

Age Can Go Without Water Overnight? Notes
Under 12 weeks Not recommended for long periods Still developing bladder control
12-16 weeks Yes, for 6-8 hours Remove water 2 hours before bedtime
4-9 months Yes, for 8 hours Still may have accidents occasionally
9+ months Yes, for 8+ hours Can usually sleep through the night without issues

My Puppy Seems Really Thirsty at Night – What Should I Do?

If your puppy seems excessively thirsty at night, don’t panic! There are several things to consider:

  1. Is your puppy drinking enough during the day? Make sure they have access to fresh water throughout daytime hours.

  2. Check the temperature. Hot weather increases water needs.

  3. Consider activity level. If your puppy had an extra-active day, they might need more water.

  4. Monitor for excessive thirst. If your puppy seems unusually thirsty all the time (day and night), consult your vet as this could indicate a health issue like diabetes, kidney problems, or infection.

Tips for Managing Your Puppy’s Water Schedule

Based on my experience and vet recommendations, here are some practical tips for managing your puppy’s water schedule:

During the Day:

  • Provide constant access to fresh, clean water
  • Clean their bowl regularly to remove drool or grime
  • Position their water bowl in an accessible spot
  • Reward them when they drink (positive reinforcement works!)

Evening Routine:

  • Remove water bowl 2-3 hours before bedtime
  • Take your puppy outside for a final potty break right before bed
  • If it’s hot, make sure they’re well-hydrated before the water goes away

Special Circumstances:

  • During hot weather, you might need to give small amounts of water at night
  • If your puppy is on medication or has a health condition, follow your vet’s specific advice
  • For very young puppies, consult with your vet about appropriate nighttime water protocols

My Practical Experience

When I brought home my Lab puppy, Charlie, I was totally overwhelmed with the conflicting advice about nighttime water. I tried leaving water out all night and ended up with puddles every morning. Then I tried removing water after 6pm, which worked better but he seemed so thirsty before bed!

The solution that worked for us was:

  1. Free access to water until 7pm
  2. One small drink (just a few sips) right before the final potty break at 10pm
  3. No water overnight
  4. Fresh water first thing in the morning (around 6am)

By 4 months old, Charlie could sleep through the night without accidents, and by 6 months, I felt comfortable leaving a small amount of water out overnight because he had developed better bladder control.

When To Stop Restricting Nighttime Water

The good news is that you don’t have to restrict water forever! Once your puppy:

  • Can consistently hold their bladder through the night
  • Has established good potty habits
  • Is fully house trained

You can start leaving water out overnight again. For most puppies, this happens somewhere between 6-9 months of age, but every dog is different.

Signs Your Puppy Needs Water at Night

While most puppies can go 8 hours without water, watch for these signs that they might genuinely need a drink:

  • Excessive panting
  • Dry gums or nose
  • Lethargy
  • Repeatedly licking their lips
  • Pacing and looking at where their water bowl usually is

If you notice these signs, offer a small amount of water (a few sips, not a full bowl).

FAQs About Puppies and Nighttime Water

Will my puppy get dehydrated without water at night?

No, as long as they have adequate water throughout the day. Most puppies naturally sleep through the night without needing water.

What if my puppy wakes up and seems thirsty?

If your puppy wakes up and genuinely seems thirsty, offer a small amount of water, but be prepared to take them outside shortly after.

Can I give ice cubes instead of water at night?

Yes! Ice cubes can be a great alternative if you’re concerned about hydration but want to limit liquid intake. They take longer to consume and provide less water volume.

Does breed affect nighttime water needs?

Yes, to some extent. Larger breeds or dogs with squished faces (brachycephalic breeds like Bulldogs) may need more water. Active breeds may also have higher water requirements.

My puppy drinks a LOT of water. Should I be concerned?

Excessive thirst can sometimes indicate health issues like diabetes, kidney problems, or urinary tract infections. If your puppy seems unusually thirsty all the time, consult your veterinarian.

When To Seek Veterinary Advice

While restricting water at night is generally safe for healthy puppies, there are situations where you should consult your vet:

  • If your puppy seems excessively thirsty all the time
  • If you notice changes in urination patterns (frequency, color, smell)
  • If your puppy seems lethargic or unwell
  • If your puppy has diarrhea or is vomiting (which can lead to dehydration)
  • If your puppy is on medication that might affect water needs

The Bottom Line

Yes, most healthy puppies can safely go through the night without water once they’re over 12 weeks old. Removing water 2-3 hours before bedtime can help with house training and reduce nighttime accidents.

However, every puppy is unique, so observe your pet’s individual needs and behavior. As they mature and develop better bladder control, you can gradually reintroduce nighttime water.

Remember – the goal isn’t to restrict water unnecessarily, but to help establish a routine that works for both you and your puppy. A well-rested puppy (and puppy parent!) is a happy one.

Do puppies need water at night?

Unless your puppy is unwell or suffering from a medical condition, you should avoid leaving water out for them at night.

Most puppies over the age of 12 weeks can go without water for 8 hours, but its inevitable that you may wake up to a mess every now and then.

Young dogs under 12 weeks are not able to hold their bladder for too long, and up until around 9 months old theyre likely to need the toilet with 10 – 30 minutes of having a drink.

By stopping water intake before bedtime, you limit the number of night time wake up calls and decrease the chances of any accidents occurring.

This is primarily the case during toilet training, before a puppy becomes a dog and is still learning the ropes.

Over time, your puppy will start to settle and sleep through the night, and when this happens, you wont need to remove their water anymore.

When do puppies start drinking water?

Before you even bring your puppy home, they will have already been introduced to to drinking water.

Puppies start drinking water at around 3 – 4 weeks of age, at the same time they switch from milk to solid food and once their teeth have started to grow.
