Up until now, she's had no problem lifting her feet or with me touching her feet. Then, like two days ago, she suddenly has started dancing and moving away when I get near her hind feet. I've checked her legs-there's no visible problems, she's not limping, there's no heat in her legs...so I don't think she's in discomfort, I think she's just being the five-year-old she is and testing me. Under any other circumstance, she would be receiving firm reprimanding, but I don't know if that's the right thing to do now. She'll lift her foot for a fraction of a second then twirl away. At first I thought she was just spooky but she's maintained this behaviour for the last few days, and I'm getting fed up. Of course, I always hound her until I have her foot for at least a few seconds, but it's really annoying when she won't stand so you can pick out her feet.
How should I deal with this?
