Can guinea pigs swim? - Brooks-Falls Veterinary Hospital
No, they shouldn't swim. That's not something that we should test out. I put mine in the bathtub with just a tiny bit of water, so they can walk in there, but I can't say I put enough in the tub to like have them try to swim. It's not one of their natural behaviors. I felt like I was torturing her because she screamed the whole time. She had some poo on her feet, so I figured I'd have her walk it off in the water, and I don't think she liked it very much.
