8 Reasons Your Cavapoo May Be Drinking A Lot (And How To Fix It)

You may be worried if you notice your Cavapoo consuming a lot of water, especially if this is a new occurrence. But don’t get too excited just yet. There might be various reasons why your Cavapoo is drinking so much water.
Keep reading to find out what they are!

How Much Should A Cavapoo Drink?

According to PetMD, adult Cavapoos should be drinking one ounce of water per pound of body weight. Adult Cavapoos should drink one ounce of water per pound of body weight, according to PetMD. A Cavapoo may weigh between 15 and 30 pounds, which means they should drink between 22 and 30 ounces of water each day.

How Much Should A Cavapoo Puppy Drink?

Cavapoo pups will need to drink a little more, around an ounce and a half of water per pound of body weight, due to their quick growth. Whether you’re concerned about your Cavapoo puppy’s drinking habits, weigh him or her and then check to see if they’re receiving enough water.

Why Is Your Cavapoo Puppy Drinking So Much Water?

They’re Too Hot

If it’s too hot outside, it might be one of the reasons your Cavapoo is drinking so much. Cavapoos are roaming about with a thick coat on, making it much more difficult for them to remain cool.

If they are hot, you may see them spending more time in the shade or attempting to cool down by jumping in the water.

A Medical Condition

In fact, the first thing you should do is rule out any medical issues. Urinary tract infections, diabetes, polydipsia, and kidney diseases can all cause excessive drinking in your Cavapoo. So, if you notice a sudden shift in their drinking habits, take them to the vet to ensure it isn’t something serious.

Too Much Dry Food

Due to the low water content of dry food, your Cavapoo may need to drink extra to compensate.

Also, if you serve your Cavapoo anything from your plate, make sure it isn’t too salty, as this may dehydrate them as well.

A Stomach Bug

It’s also likely that your dog has a gastrointestinal disease of some sort. You may notice that, in addition to thirst, they are vomiting or experiencing diarrhea. As a result, they may be drinking more water to compensate for fluid loss.

If you observe this happening, you may not think it’s a big deal, but you should definitely call your veterinarian to make sure it’s not something hazardous since diarrhea and vomiting may quickly dehydrate your dog.


It goes without saying that if your Cavapoo is exercising more frequently, it will need to drink more frequently. This might be the reason your Cavapoo refuses to stop drinking after a long run. I know it’s difficult to imagine your small Cavapoo could be getting this much exercise, but it’s quite achievable!


If you have a senior Cavapoo or a puppy, this might be the cause of their excessive drinking. Puppies need more water as they grow, and elderly dogs need more as they age and acquire ailments that affect their health and thirst.

Psychological Polydipsia

If your dog is quite healthy and has no other health problems, he or she might be suffering from psychological polydipsia. Fortunately, this is seen as a behavioral problem rather than a dangerous one. It’s also more prevalent in water-loving breeds.


Finally, the medication you’re administering to your Cavapoo may be dehydrating them. Some medications that may cause your dog to become dehydrated include anti-inflammatory meds, heart failure medications, and seizure medications.

How To Spot Why They’re Getting So Thirsty

There are a few things you can do to assist you in figuring out why your Cavapoo is thirsty. While you should ALWAYS consult with your veterinarian first, you can get some peace of mind beforehand.

They’ve Become Thirsty Suddenly

If your Cavapoo normally doesn’t drink much but can’t seem to quit, it’s a sign that something is wrong, especially if you’re stumped as to why they’d want to drink more (such as heat).

When They Are Thirstier (and When They Aren’t)

If you find your Cavapoo drinking more at certain times of the day, you might be able to figure out what’s making them thirsty. For example, if they drink more during the hottest parts of the day, you can anticipate how hot it is. You can also tell if they’re on a diet if they drink a lot more after eating. You can also assume it’s medical if they begin a new course of medicine and start drinking more.

What Can You Do If Your Cavapoo Is Constantly Drinking?

There are a few things you can do if your dog is continually drinking to keep them as comfortable and happy as possible.

Take Them To A Veterinary Clinic

The first thing you should do is take your puppy to the veterinarian. This is merely to check that there is nothing serious wrong with them and that you should not be alarmed.

Give Them Plenty Of Places To Stay Cool

You may provide them with a paddling pool, which they will like, as well as lots of well-covered and shaded areas.

Don’t Take Them For A Walk When It’s The Hottest Part Of The Day

You should never walk your Cavapoo during the hottest part of the day. Not only will this dry them further, forcing them to drink more, but it is also likely that they may suffer from heatstroke, which can be fatal in an instant.

Switching To Wet Food Is Another Option To Consider

You don’t have to entirely switch, but a 50/50 combination of dry and kibble will help your Cavapoo stay hydrated. You might also try switching their dry food because a different type may not be as dehydrating.

Make Sure Their Sodium Intake Isn’t Too High

Again, giving your Cavapoo high-sodium foods is not a good idea. This is most likely due to the treats you’re giving them, but if you notice their dog food is too salty, you could want to switch it out.

Ensure That They Have Access To Water

Unless your veterinarian recommends otherwise, continue to provide your Cavapoo with as much water as they require; Unless your veterinarian specifically tells you not to.

What Are Some Things You Shouldn’t Do?

There are a few things you should avoid doing when your Cavapoo consumes a lot more water.

Don’t Overlook It

First and foremost, make sure your Cavapoo’s thirst isn’t caused by a major issue. Keep an eye on it and speak with your veterinarian about it to ensure it doesn’t get any worse.

Don’t Forget To Let Them Out!

Your Cavapoo will need to go to the potty more if they drink more. If that’s the case, you should let them out a lot more often than normal.

Otherwise, your Cavapoo will most likely hold their pee until they are unable to, which will be quite uncomfortable for them. Here is an excellent resource to help with potty training your Cavapoo.

Can A Cavapoo Drink Too Much Water?

Water intoxication can cause vomiting, nausea, bloating, and other gastrointestinal issues. Water intoxication can cause vomiting, nausea, bloating, and other gastrointestinal issues.

Fortunately, it’s more likely to happen if your dog has been playing in the water rather than drinking it, as dogs have a proclivity for lapping up water by mistake.

Want To Train Your Cavapoo With Peace Of Mind?

If you haven’t trained your Cavapoo properly, then this is the perfect time to start. Whatever bad behavior your Cavapoo has, whether it’s barking at night or other bad behaviors, using the right training program is the key to having an obedient and happy pup.

The training program I love and highly recommend is Brain Training For Dogs.

With Brain Training For Dogs, you’ll save yourself a ton of time and effort. Instead of banging your head against the wall trying to figure out why your dog won’t listen, you’ll follow a path that has been tried, tested, and, most importantly, that’s given proven results. Not to mention the fact that you’ll be able to fit the course around your schedule, not fit your schedule around a trainer or obedience class.

So instead of worrying about whether they’re going to be well-behaved or not, you’ll only have to worry about how much fun you’ll have with them!

And in most cases, it’s still going to be:

  • Cheaper than hiring a professional.
  • Cheaper than replacing everything they might break.
  • And definitely cheaper than a lawsuit against you, if they decide to bite someone.

Just imagine how great it will feel to finally be able to trust your Cavapoo completely and never worry whether they’ll be naughty or not. Instead, you’ll have the peace of mind that you have a well-behaved pup, and the boundaries you set for them will always be there, EVEN IF YOU’RE NOT.
