The therapist says that this could improve over time or she may always have a little trouble with that leg. It's hard to say at this time. When we go for our walks you hardly notice there is anything wrong at all. When she starts to get tired (after 1.5 miles) she starts to limp. I've also noticed that she has trouble going into a sit and down. It is probably very uncomfortable for her now.
At this time we are going to continue with the underwater treadmill, but it looks like we may be reaching the end of physical therapy. Instead, we'll start introducing her to our new activity, jogging. :-)
