So...is drinking pool water actually dangerous?

So...is drinking pool water actually dangerous?

It's the world's biggest water bowl. And always topped up and crystal clear. So it's no surprise the furry family often feel that swimming pool water is theirs to drink.

But does drinking from the pool cause any health problems or stomach upsets?
Here are the fast facts on those swimming pool slurps...

Chlorinated pools
If your pool is well-maintained, the chlorine levels are surprisingly low... so low, in fact, that they rarely cause problems. In truth, compared to the mystery puddles and questionable ponds our best mates love to sample, pool water is practically Perrier. Recently treated or heavily “shocked” pools may irritate their tummy a little, but any gut upsets should be mild and hopefully short-lived. 

So while it's not recommended, a slurp from a chlorinated pool shouldn't cause alarm.

Saltwater pools
Much like the ocean, saltwater pools aren't quite as appealing as chlorinated or fresh water. But thirsty or inquisitive tongues will still be tempted.

If it's more than just a taste, that extra saltiness can have both an irritant and an 'osmotic' (drawing water in) effect. The result is the same; a squirt of watery diarrhoea.

The watch-out? Pets with kidney or heart disease where their sodium balance is crucial.

NB. While dogs aren't overly picky, cats are more discerning drinkers and will rarely drink from salty water. 

The golden rule?
Sure their curiosity will tempt them. But having a multiple bowls of cool, fresh water will stop a sip from being a big drink. 
And just make sure those bowls are in the shade. Hot water doesn't cool or hydrate a parched pet...

That choice of water will ensure that pool doesn't become a drinking problem...
