How does she act if you handle her foot? (Assuming she didn't mind that before the injury)
Are her nails well trimmed? She is probably carrying her weight slightly different on that foot now and slightly long nails could be more uncomfortable even if before they weren't a problem. I know Chester's nails got horribly long after his knee surgery because I couldn't lift his foot properly on the hurt leg and he couldn't support his weight on the hurt leg for me to lift the opposite foot for a trim.
I don't think its unreasonable to figure that her foot could still be a bit more sensitive and get sore more quickly by the end of class. How's she do on longer walks?
