Should Pets Drink More in Summer? Advice from Daventry Vets
July 20, 2026
As temperatures rise this month in Northamptonshire, keeping your pet hydrated is especially important, as pets can lose fluids quickly. For pets with certain health conditions such as kidney disease it is essential.
At Daventry Vets, many owners ask us how to tell if their pet is drinking enough. That’s why our veterinary team in Daventry have put together practical advice to help you recognise when your pet needs more water so you can keep them hydrated this summer.

Do pets need more water in summer?
Yes – pets lose more fluid through panting, grooming and activity due to the heat and for some pets there are no longer any puddles which they may like to drink from.
Our veterinary team in Daventry explain that dogs may pant more to cool down, whereas cats and small pets lose heat more passively through their skin and fur, their breathing, and the surrounding air – especially when it’s cool or moving. Some pets will naturally drink more, but others may not, which is why monitoring intake is important.
Diet also plays a role. Pets fed mainly dry food will generally need to drink more compared to those eating wet food or fresh produce, because dry diets contain very little moisture.
As a general guide, many pets will regulate their own intake if fresh water is always available. However, there are some useful ways to help.
How to keep your pet hydrated in summer
These simple steps from Daventry Vets can help maintain good pet hydration in summer, with a few small adjustments depending on your pet:
Provide constant access to water
Water should always be available. In the Northamptonshire hot weather, pets may drink little and often, so even short periods without access can increase the risk of dehydration. For small pets, this is especially important as consistent hydration supports digestion and gut health.
Change water regularly
Changing water frequently helps keep it clean, cool and free from debris. Your pet is unlikely to be as interested in stale water, so regular refreshing can encourage better drinking habits. Bottles for small pets should also be checked to ensure they are flowing properly and at the correct height. Our team in Daventry are happy to advise on the best setup for your pet.
Offer multiple and varied water sources around the home
Placing more than one bowl or bottle in different areas encourages drinking. Dogs and cats may be more likely to drink if water is nearby where they rest, while small pets benefit from backup sources in case one becomes empty or blocked.
Cats can often have preferred sources of water, bowls, water fountains, taps. For some the size of bowl or material it’s made of matter.

Keep water in cool, shaded areas
For outdoor pets or hutches, positioning water in shaded areas is particularly important.
Add wet food for cats & dogs, and water rich vegetables for rabbits and guinea pigs.
Incorporating moisture through diet can support hydration. Wet food contains a high percentage of water and can contribute to fluid intake. You can also add a small amount of water or pet-safe broth to dry food. This works really well for dogs, as usual our feline friends can be more fussy. It’s often better to offer them broth which you can buy or use the water from poaching fish or chicken ( remember not to use seasoning)
For rabbits and guinea pigs feeding water-rich greens and vegetables can help. Remember to introduce new things slowly to avoid gastrointestinal upsets.
When should I be concerned?
While some variation in drinking is normal, if your pet is not drinking, seems unwell, or shows changes in behaviour, it’s best to seek advice promptly.
Smaller pets can deteriorate more quickly if hydration levels drop. If your rabbit, guinea pig or small furry has stopped drinking entirely, <a href="01327 877767“>contact us immediately.
