I take my 3 rotties to a hydrotherapy pool, and each of them react differently. My eldest had to go initially as rehabilitation after crutiate surgery (both legs), and we started to take my boy as we can't let him off lead to free run due to behavioural issues. My middle girl didn't like it at all to start with, yet she's the one who actively seeks out puddles etc we thought she'd love it, but the first time she tried to get out the side of the pool.
Both girls now swim OK without fretting, although i wouldn't say they particularly enjoy it yet, my boy on the other hand absolutely adores his swimming sessions, so much so that he will even tolerate strange people and dogs in the room with him (they'll be taken into shower etc) whilst he's in the pool. Ordinarily he would be trying to get at them.
So what I'm trying to say is, she might love it or she might hate it.
