Summer’s here, and if you’ve got a pool, chances are your dog is treating it like a giant water bowl. But is your dog drinking pool water something you should be worried about—or is it no big deal?
As a vet (and a former dog mom), I get this question a lot. So let’s break it down: when is it okay, when is it risky, and what can you do to keep your pup safe and hydrated.

Why Dogs Drink Pool Water in the First Place
Let’s be honest—dogs don’t always have the best judgment when it comes to what they slurp up. They’ll drink from puddles, the toilet, and yes… your pool.
Some dogs drink pool water just because it’s there, especially if they’re playing and getting thirsty. Others are more curious or just love the taste of something different.
Chlorinated or salty, it doesn’t seem to matter much to them.
Is Pool Water Safe for Dogs to Drink?
A small amount of pool water now and then usually isn’t a big deal. Most well-maintained pools contain low levels of chlorine that aren’t harmful in tiny doses. But when your dog drinks pool water regularly or in large amounts? That’s when things can get a little dicey.
Here’s why too much pool water can be a problem:
- Chlorine and chemicals – While safe for swimming, pool chemicals aren’t meant for drinking. They can cause upset stomach, drooling, or even vomiting if your dog drinks too much.
- Saltwater pools – Saltwater pools aren’t chemical-free. They contain enough salt to cause issues like dehydration, diarrhea, and even sodium poisoning in large quantities.
- Contaminants -Pools can still contain bacteria, algae, or cleaning agents that could cause digestive issues—even if the water looks clean.
What Happens If Your Dog Drinks Pool Water?
Chlorine Pools
A few laps of pool water probably won’t harm your dog, but drinking too much can lead to stomach upset. Chlorine itself can irritate the mouth, throat, and digestive system—especially if a dog somehow gets into concentrated chlorine tablets or liquid.
Most pools are maintained between 1–3 milligrams of chlorine per liter, which the CDC says is generally safe for both people and pets to ingest. But here’s the catch: over time, chlorine reacts with other things in the pool (like sweat, dirt, or pee) and turns into chloramines.
These are the real culprits behind that strong “chlorine smell,” and they can irritate your dog’s skin, eyes, and nose—not to mention their gut if they’re drinking the water.
Saltwater Pools
Saltwater pools may sound gentler, but they still contain chlorine—just in lower amounts. Plus, they have added salt, which can cause diarrhea, vomiting, dehydration, or electrolyte problems if your dog drinks too much.
Saltwater pools have much less salt than the ocean (about one-tenth), but gulping large amounts can still make a dog feel pretty sick.
What If Pool Water Isn’t Properly Treated?
It’s not just over-chlorinated water that can be a problem—under-treated pool water can be just as risky. Without the right chemical balance, pools can harbor bacteria, algae, parasites, and other harmful contaminants from people, animals, or the environment.
Always monitor your pool’s pH and chlorine levels, and keep your dog out of the water until it’s been properly treated and is safe again.
Signs of Water Intoxication In Your Dog
If your dog just had a few quick licks from the pool, there’s usually no need to worry. But if they’ve been drinking large amounts of pool water, especially over a short period of time, it’s a good idea to watch for signs that their body isn’t handling it well.
Here are some symptoms of water intoxication to look out for:
Excessive drooling
Lethargy
Light pink or pale gums
Unsteadiness
Advanced symptoms include:
Eyes glazed over
Seizures
Respiratory distress or labored breathing
Collapse
If anything seems off—or if you’re unsure how much water they drank—don’t hesitate to call your vet. It’s always better to play it safe, especially when it comes to chemical exposure or dehydration.
Can Dogs Swim in Chlorine Pools or Saltwater Pools?
Yes, it’s generally safe for dogs to swim in both chlorine and saltwater pools—as long as the water is properly maintained and the chemical levels are balanced. Just make sure your dog is comfortable in the water and always supervise them, even if they’re a strong swimmer.
Keep in mind that pool water can dry out your dog’s skin and coat, especially with repeated exposure. To help prevent irritation, rinse or bathe your dog with fresh water after swimming. Avoid giving them a full bath right before swimming, since this can strip the skin’s natural oils and make them more sensitive to pool chemicals.
One often-overlooked issue is the risk of ear infections after swimming. Dogs with floppy ears or lots of fur around their ears are especially prone. To help prevent moisture buildup, use a dog-safe ear-drying cleanser after each swim—this can go a long way in keeping their ears healthy.
If you don’t have access to a pool, consider getting a dog-safe kiddie pool or using a sprinkler to give your pup a fun and safe way to cool off at home.
How to Prevent Your Dog from Drinking Pool Water
If your dog drinking pool water is becoming a regular thing, you’re probably ready to break the habit. Here are a few simple strategies that can help keep your pup’s tongue out of the chlorine (or salt):
1. Keep Fresh Water Close By
This is the easiest fix and surprisingly effective. Make sure your dog always has access to a big, clean bowl of water near the pool area. If they’re playing and get thirsty, they’ll go for the easier—and safer—option.
2. Try a Pet Water Fountain
Some dogs just prefer moving water. A pet-safe fountain gives them the fresh taste they want without the chemicals. Place it outside where they hang out the most, especially during pool time.
3. Schedule Breaks and Cooldowns
Dogs will often drink pool water when they’re overheated. Keep play sessions short, especially in hot weather, and bring them to a shady spot for a water break before they get too thirsty.
4. Use Training + Redirection
If your dog goes for the pool every time, you can teach them to stop. A simple “leave it” command, paired with praise and redirection to their water bowl, can work wonders over time.
5. Supervise Pool Time
I know—it’s not always realistic to be outside every second. But if your dog drinking pool water has been a problem, it’s best to supervise until the habit fades or you’ve successfully trained around it.
Final Note – Dog Drinking Pool Water
Your dog drinking pool water isn’t always a red flag, but it’s definitely something to monitor. A few laps here and there? Probably fine. Gulping it down every time they’re outside? Time to make a plan.
Keep fresh water available, watch for signs of overdoing it, and don’t hesitate to talk to your vet if you’re concerned.

Frequently Asked Questions
How long can my dog splash around in the pool?
Most dogs should only play in the pool for about 10 to 30 minutes at a time. Some dogs get tired faster than others, especially puppies, older dogs, or dogs that aren’t used to swimming.
Even if your dog seems excited, take breaks often and watch for signs they’re getting tired—like heavy panting, slowing down, or trying to get out of the water. Always have fresh water and a shady spot nearby.
We don’t have a pool but go to the beach or lake a lot. Is it okay if my dog drinks ocean, lake, or Gulf water?
It’s best not to let your dog drink from any natural body of water, including the ocean, Gulf, or lakes. Saltwater can cause serious problems like vomiting, diarrhea, and even seizures.
Lake and Gulf water may contain harmful bacteria, algae, or parasites that can also make your dog sick. Always bring clean, fresh water and offer it often so your dog doesn’t drink from the beach or lake.
