How to Stop Dog From Drinking Pool Water?

On a hot summer day, if your dog is enjoying family time near the pool, he may see that backyard pool as a huge water bowl and slurp some water.

You should worry about your fido as pool water is safe to swim in but not safe to drink. Even though chlorine is safe at normal levels, the pool should never be your pet’s source of water.

How to Stop Dog From Drinking Pool Water

Pets should be prohibited from drinking in pools. Pool water contains chemicals other than chlorine, such as algaecide which may be harmful to the digestive system.

And if your pool isn’t well maintained, algae, excessive chemicals, and other things can also cause trouble.

What Happens When Dogs Drink Out of Too Much Pool Water?

In general, an occasional drink of pool water does not cause damage to a dog. Even humans inadvertently drink small amounts of pool water and rarely experience problems. However, your dog should not use the pool as a primary beverage bowl.

Too much water can be fatal as well. Water intoxication occurs when there is more water that can be processed in body fluids. This causes extreme depletion of sodium levels, resulting in a shift in the balance of electrolytes.

What Happens When Dogs Drink Out of Too Much Pool Water

Drinking excess amounts from a pool of saltwater will lead to the same issues as commonly chlorinated pools. Furthermore, excessive salt intake can lead to diarrhea or electrolyte imbalances that can rapidly become life-threatening.[1]

Fortunately, pool water holds much less salt than the ocean. On the skin and mucous membranes of dogs, especially those with sensitive skin, saltwater pools may be more gentle than chlorinated pool water.

How Is Pool Water Harmful to Dogs?

An uncleaned swimming pool, or a pool that is not well maintained may have some harmful effects on your dog[2]. It will be even more harmful if your dog accidentally drinks the same water.

How Is Pool Water Harmful to Dogs
  • Toxins

Pool water contains pool chemicals, consisting mainly of chlorine and algaecides that keep the pool disinfected and free from plant life.

These chemicals may risk the dog’s health despite their beneficial purpose for pool maintenance. The levels of these toxins are deliberately low to prevent harm from occurring, as people ingest pool water by accident on a routine basis.

While most pets will not develop an issue from the occasional small pool of water drink, large amounts of pool water may cause problems, along with irritation or burning to the esophagus.

In addition, there may be a life-threatening reaction if the dog is allergic to the chemicals in the pool.

Guide: If you have a senior dog, a dog with arthritis, or a dog with other mobility issues, it may be time for the dog ramp.
  • Microorganisms

Most of the chemical treatment is used to limit the growth of these microorganisms by bacteria and fungi who love pools, although trace amounts can remain even in the most well-maintained pool.

One such bacterium is found in pools. E is Escherichia coli (E. coli). Coli is absorbed via fecal ingestion. It will lead to many diseases.

  • Aspiration

When water or other foreign material enters the lungs, aspiration occurs. Because of inappropriate posture while drinking or the sheer amount of water available, pets drinking pool water can accidentally aspire to water.

Aspiration typically results in the swallowed liquid being coughed, gagged, and regurgitated.

Aspiration pneumonia is a serious medical problem, and animals showing signs, including breathing problems, loud breathing, anxiety, and dark lip and gum tinting, require immediate medical attention.

  • Stomach Upset

The most common problem with pets drinking pool water is stomach upset. Coldwater, like water heavily laden with chemicals, increases the chance of stomach upset.

Dogs that drink pool water to ward off dehydration are more prone to develop stomach upset.

Vomiting, regurgitation, and pain as a result of drinking pool water are common symptoms of stomach upset. While stomach upset is not a life-threatening problem, constant vomiting can lead to dehydration, which may be fatal.

What Are the Other Risks of Exposure to Pool Water?

Since most freshwater pools are treated with chemicals, particularly chlorine, it is a good idea to keep swimming sessions relatively short, as extended time in chlorinated water may cause eye and skin irritation in sensitive dogs.

And if the pool has a high chlorine level, it can also irritate the airways of your pet.

Dogs who swim frequently may have more frequent infections of the skin. Although owners may wonder whether this is correlated with exposure to chlorine, repeated infections are more likely to be associated with moist ears than the chlorine itself.[3]

If your pet is susceptible to chronic ear infections, then you should check to your veterinarian, in most cases, they prescribe a drying solution after swimming.

Are There Chlorine Alternatives For Pool?

If you think it’s a good solution to limit chemicals, think again! Improperly treated water in the pool can contain a variety of microorganisms including bacteria, algae, fungi, and parasites.

These can affect you and your dog via accidental ingestion, inhalation, or contact with skin and mucous membranes.

Bromine is the most popular alternative to chlorine for use in the pool and spa. Bromine, a close cousin to chlorine, has a less pungent smell and less common side effects of bleaching.

People who find chlorine irritating to their eyes or skin say such effects are less likely to be caused by bromine.

Because of these milder properties, people may prefer bromine, but it is more expensive than chlorine and less stable when exposed to sunlight, making it a poor choice for outdoor pools.

Do contact with a professional pool cares, they will direct you if bromine is a good choice for your situation.
