Pets and tab water

Just found out that we SHOULD NOT drink the tab water under no circumstances. What about my dog and my cats drinking it? Yes or No. Will it harm them if they have already done so?

You need to buy your pets EVIAN, only Evian!  You're joking right?   

Pets can drink tap water, they can drink out of puddles in the street.

No. I wasn't joking. I found  out the answer from a local. But thanks anyway.

Pets are fine with tap water
