Medium dogs (20-50 lbs): 600-1500ml daily.

Why Water Is A Lifesaver For Dogs
Water is the foundation of your dog’s body. Just like humans, dogs use water for almost every bodily function.
It regulates their body temperature, lubricates their joints and aids digestion. But water also helps their kidneys filter out toxins and prevent build ups in their system.
Dogs are affected by their environment and lifestyle. On hot days or after intense exercise they’ll drink more. When it’s hot your dog’s body is working harder to cool down which can lead to increased thirst.
Panting helps dogs release heat but it also causes them to lose moisture so they’ll need to drink even more to stay hydrated.
And a dog that’s constantly running around or playing will need more water than one that spends most of the day lounging indoors. Always take into account the ambient temperature and your dog’s activity level when calculating how much water your dog should drink.

How Diet Affects Your Dog’s Water Intake
Ever noticed your dog drinks more when they’re eating kibble than when you give them wet food? There’s a good reason for that!
Wet food or canned food already contains a lot of water – up to 75-80% water – while dry food (kibble) contains only around 10% water. So dogs on a dry diet need to drink more water to make up for the lack of water in their meals.
Here’s a comparison of how different types of food affect your dog’s hydration:
Dry food:
Dogs eating dry food will need to drink more water as kibble doesn’t provide much hydration. Make sure they always have access to a fresh water bowl.
Wet food:
If your dog eats wet or canned food they’re already getting a good amount of water through their diet. This can reduce the amount of water they need to drink directly.
For dogs on a dry diet you can increase their water intake by mixing water into their kibble or even switching to a food with higher moisture content. If your dog is eating wet foods but not drinking much from their bowl they might still be getting enough water. Always monitor their hydration levels by checking their gums, skin elasticity and overall behaviour.
The Age Factor: How Older Dogs Drink
As dogs age their bodies go through changes that can affect their thirst levels. Older dogs may drink less water either due to reduced activity levels or age related health issues like arthritis which makes it harder for them to get up and walk to their water bowl frequently.
This reduced drinking can lead to chronic dehydration which isn’t always obvious. An older dog’s ability to sense thirst may diminish with age which means it’s even more important to make sure they’re getting enough water.
If you notice your senior dog isn’t drinking enough consider placing multiple water bowls around your home to encourage them to drink more.
Underlying issues
On the other hand increased thirst in older dogs can be a sign of underlying issues like kidney disease, diabetes or Cushing’s disease. If your older dog is suddenly drinking more water than usual it’s a good idea to get your vet to check.
How Do I Know If My Dog Is Dehydrated
While most dogs are good at regulating their water intake there are times when they may not drink enough and dehydration can creep up on them. Signs of dehydration in dogs are often subtle but important to catch early. Some common signs are:
Can My Dog Drink Too Much Water?
While not as common for a dog to drink too much water, drinking too much and developing water intoxication can happen. The underlying cause is when a dog drinks too much water in a short period of time which can dilute their body’s sodium levels and cause serious health problems.
Symptoms include bloating, lethargy, vomiting and in severe cases seizures. This is more likely to happen during playtime in water – like if your dog is drinking constantly while swimming.
How to Keep Your Dog Hydrated
Keeping your dog hydrated doesn’t have to be hard. Here are some simple tips to get a healthy dog drinking enough:
Fresh clean water always: Dogs will drink from a clean bowl. Refill and clean the water bowl at least once a day.
Get a pet fountain: Some dogs prefer running water and a fountain will encourage them to drink more.
Flavor enhancers: Add a splash of low sodium broth or a few ice cubes to their water.
Wet foods: If your dog doesn’t drink much water consider adding more wet foods to their diet to help boost their hydration.
Multiple bowls: Place water bowls in different areas of the house especially if you have a big house or your dog has limited mobility.
By checking your adult dogs water intake and adjusting as needed you can keep them happy and hydrated all year round.
