Penny is 9 weeks old and we are starting pad training. She is in a playpen when unsupervised which has a pad at one end for her to use. I try to reward her every time she uses the potty pad, whether it is in her pen or on the pad in our bathroom. I have ZiwiPeak treats, but she isn't able to chew them yet and isn't very interested. She doesn't seem very food motivated. What is another way to reward her for correct behavior besides treats? I do tell her "good girl!" and make a big fuss every time she potties in the right area, but I just wanted some input .
