Cacao has puppy classes every Sunday but this past Sunday, because of Easter. But she was doing so well. And now she won't come when I call or sit when I tell her. Is this normal. I am still working with her. I won't give up but I guess I am just looking for you all to tell me this is normal. That all this work will pay off. I know she is a great puppy. And we are working so hard. I just don't know why we are starting not to do as I ask. She doesn't get a treat if she doesn't do it. So I guess less treats.
