ardam, formerly CDK9 Raw, has always built our raw dog food diets around a simple fact: moisture matters as much as protein. Hydration plays a quiet but critical role in your dog's digestion, joint health and kidney function, and many Australian dog owners, especially through hot Sydney summers, do not realise how much of their dog's daily water intake should come from food rather than the water bowl alone.
In this guide we break down why raw food is naturally more hydrating than kibble, how much moisture your dog actually needs, and simple ways to keep your dog topped up on hot days.
Why Moisture Content Matters
Fresh raw meat typically contains around 65 to 75 percent moisture, compared with roughly 8 to 12 percent in dry kibble. That difference is significant when you consider that dogs, like most mammals, get a meaningful portion of their daily water needs from food rather than drinking alone. A dog eating a dry diet has to compensate almost entirely through the water bowl, and many dogs simply do not drink enough to make up the difference on their own.
Adequate hydration supports healthy digestion, helps the kidneys flush waste efficiently, and keeps joints lubricated. Some evidence suggests that dogs on higher-moisture diets may produce more consistent stool and show steadier energy levels, though individual results vary and hydration needs differ by dog.
How Raw Feeding Naturally Hydrates Your Dog
Because ardam's raw meals are built from fresh meat, organ and bone rather than dehydrated or extruded ingredients, your dog is absorbing water with every bite. This is one of the most overlooked benefits of switching from kibble to raw, particularly for dogs that are naturally reluctant water drinkers or for households in warmer parts of Australia where dehydration risk is higher during summer.
If you are unsure how a raw diet would fit your dog's current routine, our free meal planner quiz factors in your dog's age, weight and activity level to suggest a feeding plan, including guidance on portion sizes that naturally support good hydration.
Raw vs Freeze-Dried: A Hydration Comparison
Freeze-dried raw diets have become popular for their convenience, but the freeze-drying process removes almost all of the natural moisture from the meat. While freeze-dried food still offers many of the nutritional benefits of raw feeding, it requires rehydration with water before serving to restore some of that moisture, and even then it will not always match the water content of fresh raw meat. If hydration is a specific priority for your dog, fresh raw is generally the more moisture-dense choice.
Signs Your Dog May Not Be Getting Enough Water
Common signs of mild dehydration in dogs include dry or tacky gums, reduced skin elasticity, low energy and darker urine. If you notice any of these signs persisting, particularly during hot weather, it is worth checking in with your vet rather than assuming diet alone will resolve it. Dogs with certain health conditions have specific hydration needs that a general feeding guide cannot account for.
For broader, independent guidance on canine hydration and general wellbeing, the MSD Veterinary Manual is a useful reference point alongside your own vet's advice.
Simple Ways to Boost Hydration Beyond Diet
Alongside a moisture-rich raw diet, a few simple habits help keep your dog topped up, particularly during an Australian summer:
- Keep multiple fresh water bowls around the house and refresh them at least twice a day.
- Add a small splash of water or bone broth to meals on especially hot days.
- Avoid strenuous exercise during the hottest part of the day and offer water breaks during walks.
- Watch for early signs of overheating, particularly in flat-faced breeds or senior dogs.
How Much Water Does a Dog Actually Need?
As a general guide, dogs need roughly 50 to 60 millilitres of water per kilogram of body weight per day, though this varies with activity level, temperature and diet. A dog eating a high-moisture raw diet will naturally need to drink less from the bowl to meet that total, since a large portion is already coming from meals. This is one reason some owners notice their dog drinking visibly less water after switching to raw, which is expected rather than a cause for concern.

Hydration and Life Stage
Puppies and senior dogs both have specific hydration considerations. Puppies have less capacity to store water reserves and can dehydrate more quickly, while senior dogs may have reduced thirst drive or kidney changes that affect fluid balance. A moisture-dense raw diet can help support both groups, though any specific health concern should always be discussed with your vet directly rather than managed through diet alone.
Hydration Tips for Active and Working Dogs
Dogs with higher activity levels, whether that is regular long walks, agility training or working roles, lose fluid faster through panting and exertion. If your dog is particularly active, consider offering water before and after exercise rather than only during, and keep an eye on how quickly they finish their water bowl on hot training days. A raw diet's natural moisture content gives active dogs a helpful baseline, but it should not replace easy access to fresh water during and after exercise.
Sydney's warmer months in particular call for a bit more attention to timing walks earlier or later in the day and carrying water on longer outings, since pavement and sand can also intensify heat exposure on paws and overall body temperature.
Building Hydration Into Your Dog's Daily Routine
Small, consistent habits tend to matter more than occasional big gestures when it comes to hydration. Refreshing water bowls at the same times each day, placing an extra bowl somewhere your dog spends a lot of time, and keeping meals consistent in moisture content all add up over a week. If you are transitioning from kibble, our first-time raw feeder guide covers what else typically changes in the first month, including water bowl habits.
Frequently Asked Questions
Does raw dog food really contain more water than kibble?
Yes. Fresh raw meat is typically 65 to 75 percent moisture, compared with around 8 to 12 percent in most dry kibble.
Will my dog drink less water after switching to raw?
Many owners notice their dog drinking less from the bowl after switching, which is expected since more hydration now comes from food.
Is freeze-dried raw food as hydrating as fresh raw?
Not quite. Freeze-drying removes most moisture, and even with rehydration it typically will not match fresh raw meat's natural water content.
How can I tell if my dog is dehydrated?
Dry or tacky gums, reduced skin elasticity, low energy and darker urine are common signs. Persistent symptoms should be checked by a vet.
Is hydration more important in summer?
Yes, particularly in warmer parts of Australia, dogs lose more fluid through panting and heat regulation and need extra support staying hydrated.
Can I add water to my dog's raw meals?
Yes, a small splash of water or bone broth is a simple way to boost hydration further, especially on hot days.
Do puppies need more water relative to their size?
Puppies have less capacity to buffer fluid loss and can dehydrate faster than adult dogs, so consistent access to water and food moisture matters.
How do I know how much raw food to feed for my dog's size?
Our meal planner quiz calculates a tailored feeding plan based on your dog's weight, age and activity level.
