Yes, they can! And how.

They float, too, because they're so chubby. So if he's not keeping his head above water, it's either because he likes it (I have one that likes to blow bubbles under water) or because he's not all there in the smarts department.

As for whether or not he LIKES being in the water... it depends partly on water temps? They like it strictly room temp, and I'd 2 out of 3 seem to be mostly concerned with GETTING OUT.

But be warned: most of them take water at any temperature as an invitation to have a bowel movemetn.
