Neither will swim, they don't like water touching their bellies!!
We went walking in a river and they were fine, untill the water got deep.
Buddy runs from the hose when I am using it, Sierra will bite at the water comming out of the hose then run away before it gets her
I bought a little pool for them last year... Buddy just though of it as a HUGE water bowl, then when it was empty he though it was a toy. Sierra stood in it .... once..
