Maybe string cheese? Mom to Hot Rod is right about not feeding beforehand either.
Have you asked the class teacher? It may simply be that she is less food motivated - she might work better for praise or a favorite toy.
One thing I have read is that you are always competing with the environment for your dog's attention. Also keep in mind that dogs tend to compartmentalize a lot. So "Sit while at home alone with Mommy" is an entirely different proposition than "Sit in a strange place with tons of cool stuff going on around me."
Also, maybe try exercising her before class so she has a little less raw energy. |
