The 'Hero' singer decided to bond with her pets while exercising and admits she had a great time splashing around with the pampered pooches.
She tweeted: 'Just took a swim w/all the puppies in the pool. Very adorable. (sic)'
Mariah – who is married to rapper-and-presenter Nick Cannon – has previously admitted she spoils her Jack Russell dogs Cha Cha and JJ and they even have their own entourage.
Speaking on the set of an advertisement she was shooting, she said: "My puppies are starring in this ad with me, too. I had my team with me but the pups had a mini-entourage of their own, of course! And why wouldn't they? It was a big shoot and even my entourage had an entourage - my stylist had an assistant, my security had extra security.
"The shoot was based on the fact that some people think I'm a demanding diva. I have no idea why people have that impression!"
