As humans we understand how important sleep is for our health and wellbeing. But did you know that quality sleep is just as important for dogs?

On World Sleep Day we take the opportunity to recognise the vital role sleep plays in the lives of both people and animals. Getting enough rest helps dogs stay physically healthy, emotionally balanced and full of energy.

In this guide we will explore why sleep matters for dogs, how much sleep they really need and how the right diet can support better sleep and overall wellbeing.

Why is sleep vital for dogs?

Just like humans, dogs rely on sleep to recharge their bodies and minds. When dogs get enough restful sleep it supports several important areas of their health.

Physical health and recovery

Sleep helps recovery from physical activity, repair tissues and support muscle growth. This is especially important for active dogs, working breeds or dogs that enjoy lots of exercise as their bodies need time to recover.

Mental health and cognitive function

During sleep dogs process experiences and emotions from the day. Quality sleep supports brain function, memory and learning helping them remain alert and responsive.

Immune system

A well rested dog has a stronger immune system. Sleep allows the body to repair itself and helps dogs fight off infections and recover from illness more effectively.

Behaviour and emotional balance

Dogs that do not get enough sleep may become irritable, anxious or overly reactive. Consistent, restful sleep helps promote calmer, more balanced behaviour.

How much sleep do dogs need?

If it seems like your dog spends a lot of time sleeping that is completely normal.

On average dogs sleep between 12 and 14 hours per day. However, the exact amount depends on several factors including age, breed and activity level.

  • Puppies often sleep up to 18 – 20 hours as they grow and develop
  • Senior dogs may need more rest due to reduced energy levels
  • Large breeds typically sleep longer than smaller breeds
  • Highly active dogs still need quality rest to recover

The key is not just how long your dog sleeps but how restful and uninterrupted their sleep is.

Many owners don’t realise that nutrition plays a major role in sleep quality. The food your dog eats helps regulate hormones, support brain health and promote relaxation.

Here are some ways the right diet can help improve your dogs sleep.

  • Balanced nutrition supports healthy sleep cycles
    A well balanced diet containing high quality protein, healthy fats, vitamins and minerals supports the body’s natural sleep processes.
    Theses nutrients help regulate sleep related hormones such as melatonin and serotonin which control the natural sleep-wake cycle.
  • Tryptophan helps promote relaxation
    Tryptophan is an amino acid that supports the production of serotonin often referred to as the feel good neurotransmitter.
    Foods rich in tryptophan including turkey and chicken may help promote relaxation and support healthier sleep patterns in dogs.
  • Magnesium helps calm the nervous system
    Magnesium is known for helping relax muscles and calm the nervous system making it an important mineral for restful sleep
    Dog friendly foods that naturally contain magnesium include, pumpkin, sweet potatoes and leafy greens. These ingredients can help support relaxation before bedtime.
  • Omega-3 fatty acids support brain health
    Omega-3 fatty acids play a key role in brain health, mood regulation and reducing inflammation. Sources such as salmon and fish oil can help dogs feel calmer and more balanced which may contribute to improved sleep quality.
  • Avoid heavy meals before bedtime
    Just like humans, dogs may struggle to sleep if they eat a large meal right before bed. Heavy meals can cause digestive discomfort or restlessness making it harder for your dog to settle down. Feeding a lighter evening meal can support better digestion and more restful sleep.
  • Creating the perfect sleep environment for your dog
    Nutrition is important but your dogs sleep environment also plays a big role in how well they rest. To help your dog sleep comfortably make sure they have:
    • A quiet, safe sleeping area
    • A comfortable and supportive bed
    • A calm, low stress environment
    • Minimal nighttime disturbances

A cosy sleep space can make a huge difference in helping your dog relax and enjoy deeper, restorative sleep.

On World Sleep Day it is worth remembering that sleep isn’t just a luxury for our pets, it is an essential part of their health and happiness. By providing balanced nutrition, a calm environment and a consistent routine you can help your dog enjoy the rest they need to thrive.
