Practical advice on pet hydration, from Blythwood Vets in North London.
Getting pets to drink enough water can feel surprisingly tricky, especially with cats. But good hydration is one of the simplest ways to support your pet's health, energy levels and comfort. The good news is that small changes can make a big difference.
Here's an easy, down to earth guide to helping both dogs and cats drink more, what to watch for, and how the team at Blythwood Vets can help.
Why water really matters
Water helps keep everything ticking along inside your pet's body.
Good hydration supports
- Healthy kidneys and bladder
- Digestion and appetite
- Temperature control, especially in warm weather
- Joint and muscle function
- Overall energy and wellbeing
Pets that do not drink enough can become dehydrated without owners realising, particularly cats.
Why some pets do not drink much
Not all pets are natural big drinkers. If you've noticed your cat not drinking water, you're not alone — it's one of the most common questions we hear.
Common reasons include
- Cats prefer moving water
- Bowls placed near food or litter trays
- Water that is not fresh enough
- Stress or changes at home
- Feeding mainly dry food
Understanding these habits helps you encourage better drinking without forcing it.
Water fountains: why they help
A cat water fountain is especially popular with cats, but many dogs like them too.
Benefits of fountains
- Flowing water smells fresher to pets
- Encourages curiosity and play
- Often leads to more frequent drinking
- Keeps water cooler and cleaner
If your pet is unsure at first, place the fountain next to their usual bowl and give them time to explore.
Wet food and hydration
Food can play a big role in water intake.
Wet food helps because
- It contains much more moisture than dry food
- It adds water without your pet having to drink
- It can support urinary health, especially in cats
You do not always need to switch fully to wet food. Even adding one wet meal a day can help boost overall hydration.
The team at Blythwood Vets can advise on the right balance for your pet.
Simple ways to encourage drinking
Small tweaks often work best.
Try
- Using ceramic or metal bowls instead of plastic
- Placing multiple water bowls around the house
- Refreshing water at least once a day
- Adding a splash of water to food if suitable
- Offering ice cubes as a treat for dogs in warm weather
Some pets prefer quiet corners, others like drinking where you are. Let them choose.
Hydration signs to watch for
Pets do not always show dog dehydration signs or feline equivalents clearly.
Keep an eye out for
- Lethargy or low energy
- Dry gums
- Reduced appetite
- Dark or strong smelling urine
- In cats, fewer visits to the litter tray
If you are worried, it is always better to check.
When a sudden change in drinking is worth a vet check
Tweaks at home are great for the day-to-day, but a noticeable change in how much your pet is drinking is worth a proper conversation with the practice rather than just adjusting their bowl.
A clear increase in drinking can sometimes be an early sign of conditions like kidney disease, diabetes, an overactive thyroid in cats, or Cushing's disease in dogs. A sudden drop in drinking, especially in cats, is also a red flag and shouldn't be ignored.
If you spot a change that doesn't seem to be explained by hot weather, more exercise, or a recent food change, please book an appointment with Blythwood Vets. Catching these things early often makes a real difference to how easily they can be managed.
How your vet can help
If hydration is a concern, the team at Blythwood Vets can:
- Check for dehydration or underlying issues
- Advise on diet choices to support water intake
- Help manage kidney or urinary conditions
- Recommend practical changes that suit your pet
For older cats with kidney concerns, we run a dedicated senior cat clinic at Blythwood Vets.
Keep it simple and consistent
Encouraging pets to drink more does not need to be complicated. A cleaner bowl, a fountain, or a bit more wet food can all make a difference. The key is finding what works for your dog or cat and sticking with it. If you are unsure, have a chat with Blythwood Vets. A quick check now can help prevent problems later and keep your pet feeling their best.
Quick answers
How much water should my dog drink in a day?
As a rough guide, dogs need around 50 to 60 ml of water per kg of body weight per day. Active or hot-weather days will be higher. Wet food contributes towards this.
Why is my cat not drinking water?
Many cats prefer moving water, dislike bowls placed near food or litter, and have low natural thirst drives. Try a ceramic or metal bowl, a fountain, or adding a wet meal to boost overall fluid intake.
When should I worry about my dog drinking too much water?
A clear, sustained increase in drinking can be an early sign of kidney disease, diabetes, or Cushing's disease in dogs. If your dog is suddenly emptying their bowl much faster than usual, book a vet check.
Can older cats benefit from a water fountain?
Yes. Older cats with early kidney disease often drink more readily from flowing water. Fountains are a simple, low-cost way to support hydration in senior cats. Your vet may also recommend a renal diet alongside.
