Is Your Dog or Cat Drinking Enough Water?
Most pet parents know that water is important.
But when we think about hydration, we usually focus on how much water our pets drink from their bowl.
What many people don’t realise is that food can be a major source of hydration too.
In fact, the type of diet your dog or cat eats can significantly affect how much moisture they consume every day.
Moisture Matters
Water plays an important role in almost every function of the body.
It helps regulate body temperature, supports digestion, transports nutrients, lubricates joints and helps the kidneys remove waste products.
When pets don’t get enough moisture, their bodies need to work harder to maintain normal function.
Cats are particularly vulnerable because they naturally have a low thirst drive. Their wild ancestors obtained most of their water from prey, which typically contains around 70–80% moisture.
Dogs generally drink more readily than cats, but they can also benefit from additional moisture in their diet.
Not All Pet Foods Contain The Same Amount Of Moisture
Different types of pet food contain vastly different moisture levels.
Typical Moisture Content
Dry kibble
- Around 6–10% moisture
Air-dried food
- Around 10–15% moisture
Freeze-dried food (fed dry)
- Around 5–8% moisture
Fresh, raw or gently cooked food
- Around 65–80% moisture
To put this into perspective, a pet eating fresh food may naturally consume several times more moisture through their meals than a pet eating dry kibble.
Why This Matters
Imagine eating dry crackers for every meal and relying entirely on drinking water to make up the difference.
That’s essentially what many pets on dry diets are doing.
While many dogs and cats will drink enough water to survive and remain healthy, they often need to consume significantly more water from their bowl to compensate for the low moisture content of their food.
Some pets do this successfully.
Others don’t.
Cats are especially known for drinking less than they ideally should.
Signs Your Pet May Need More Moisture
Hydration status isn’t always obvious, but some signs that may suggest your pet could benefit from additional moisture include:
- Concentrated or strong-smelling urine
- Small amounts of urine
- Dry stools
- Constipation
- Reduced enthusiasm for drinking
- A history of urinary issues
These signs don’t necessarily mean dehydration, but they can be worth discussing with your veterinarian.
Simple Ways To Increase Moisture Intake
You don’t necessarily need to completely change your pet’s diet overnight.
Some simple ways to increase moisture intake include:
- Adding water or broth to kibble
- Rehydrating freeze-dried foods before feeding
- Offering fresh or raw meals as part of the diet
- Adding moisture-rich toppers
- Feeding species-appropriate fresh foods where suitable
- Providing multiple fresh water sources around the home
Even small changes can contribute to overall hydration.
The Bottom Line
When it comes to hydration, it’s not just about how much water your pet drinks.
It’s also about how much moisture they’re getting from their food.
Fresh foods naturally contain significantly more water than dry kibble, helping contribute to your pet’s daily moisture intake.
Whether you feed raw, gently cooked, freeze-dried or kibble, understanding where your pet’s hydration comes from can help you make more informed choices about their diet.
Because sometimes, hydration starts long before your pet reaches the water bowl.
