Here's a movie of Ollie from earlier today in his first hydrotherapy session. Sooz said he wasn't overly keen, but he did get into it after a lap or two. The idea is that he will eventually be able to swim on his own without his helper. The exercise is great to help rehabilitate his hind legs, although he's sure feeling it tonight. He's pretty stiff, although that is normal.
Sooz got the details for the swimming vest he wore and we'll buy him one before we leave for Aspö. If he's able to get stronger, and also get in some swimming practice, that sounds like a great deal all around.
