My youngest Honey is the same way, she freaks out everytime I try to cut her nails. I called it the clip and run game. I clip, then she runs, I chase, I clip, she runs, I chase, etc...
What I did was hold the clippers but I wouldn't clip her nails. I would hold them, let her see them, touch her feet, then put the clippers up and go about the day.
We've gotten to the point where she will let me clip all the nails on one foot and then she takes off. Still 3 more feet to go but it worked for the first one.
Bascially, make the process as stress free as possible.
Question, is she like this when you touch her feet? Or just when you try to clip her nails?
