Vaquita has always given me problems with clipping her toenails. Just getting down the clippers and touching her paws used to make her start crying. Slowly I had been working on her to let me mess with her nails, but she'd start acing up, jerking her feet away, etc. I know I'm not hurting her, she has clear nails, and I can see. But she was traumatized when I got her.
I am proud to say that yesterday was the very first grooming session where she gave me each paw in turn when I asked for them, and let me clip each nail without a hint of argument! She got bacon for that trick!
Woo Hoo!!! Progress!
