The Truth About Bathing Your Dog: Why Water Temperature Matters More Than You Think
Many dog owners assume that their pup would enjoy a hot bath during winter and a cool bath during summer—just as we often do ourselves. It's also common to see seasonal grooming promotions that highlight warm winter baths as an extra treat for dogs.
However, unlike humans, dogs don't necessarily become more comfortable with hotter baths simply because the weather is colder. In fact, the ideal bathing temperature for most dogs remains surprisingly consistent throughout the year.
Understanding why water temperature matters can help you make informed decisions—whether you're bathing your dog at home or taking them to a professional groomer.
Why Does Water Temperature Matter?
Bathing isn't just about getting your dog clean.
The temperature of the water can affect your dog's comfort, stress levels, skin health and overall grooming experience. A bath that feels comfortable to us may feel too hot or too cold for a dog.
Unlike people, dogs can't tell us when the water feels uncomfortable. Instead, they may tense up, try to move away, shiver or become reluctant to stay in the bath. That's why paying attention to water temperature is such an important part of creating a positive bathing experience.
Water temperature can influence:
- Comfort
- Stress levels
- Skin and coat health
- Circulation
- The overall grooming experience
Is Hot Water Better in Winter?
Not necessarily.
It's easy to think that if the weather is cold, a hotter bath must feel better. However, excessively hot water can do more harm than good.
Hot water can:
- Dry out the skin and coat
- Remove too much of the skin's natural protective oils
- Cause unnecessary discomfort
- Place additional physiological stress on puppies, senior dogs and dogs with certain medical conditions
A comfortably warm bath helps dogs stay relaxed without exposing them to unnecessary heat.
Should Dogs Have Cold Baths in Summer?
Again, not usually.
On a hot summer's day, it might seem kind to cool your dog down with cold water. However, very cold water can feel startling and uncomfortable.
Cold water may:
- Cause some dogs to tense their muscles
- Increase stress or anxiety during bathing
- Make the bathing experience less predictable, especially for nervous or sensitive dogs
Rather than choosing hot water in winter or cold water in summer, it's generally better to keep the water comfortably warm all year round.
So, What Is the Ideal Water Temperature?
For most healthy dogs, a water temperature of approximately 37–39°C (98.6–102.2°F) provides a comfortable bathing experience.
This range is close to a healthy dog's normal body temperature, which is typically around 38.3–39.2°C. Keeping the water within this range helps minimise sudden temperature changes while keeping your dog comfortable throughout the bath.
Instead of changing the water temperature dramatically with the seasons, aim for a consistent, comfortable temperature every time.
What About Puppies, Senior Dogs and Dogs with Medical Conditions?
Some dogs are more sensitive to temperature than others.
Puppies are still developing their ability to regulate body temperature. Senior dogs may be less able to cope with sudden temperature changes, and dogs with certain medical conditions may be more easily affected by unnecessary physical stress.
For these dogs, avoiding water that is excessively hot or cold is especially important. A stable, comfortably warm bath is usually the safest and most comfortable option.
If your dog has a diagnosed medical condition, such as heart disease, it's always worth asking your veterinarian whether they have any specific bathing recommendations.
Water Temperature Is Only One Part of a Great Bath
Choosing the right water temperature is important, but it's only one part of helping your dog feel comfortable.
A positive bathing experience also depends on:
- Gentle handling
- Appropriate water pressure
- A calm and quiet environment
- Thorough drying afterwards
- Understanding your dog's body language and responding to how they're feeling
When these factors work together, bath time becomes less stressful and more predictable, helping many dogs become more comfortable with grooming over time.
Final Thoughts
For most dogs, the goal isn't a hot bath or a cold bath—it's a consistently comfortable one.
Keeping the water at a stable, comfortable temperature helps support your dog's skin, coat and overall wellbeing, while making bath time a more enjoyable experience.
Whether you're bathing your dog at home or visiting a professional groomer, remember that small details matter. Sometimes, something as simple as the right water temperature can make a bigger difference than most people realise.
