Frito is really cute!!! I recommend having your vet check to make sure that he doesn’t have enlarged anal glands which could be causing some discomfort/even pain back there. If he doesn’t have any anal gland issues, you can try restraining him in a thick towel before wiping his butt if he needs it to avoid getting bitten. Good luck!

    From a behavior standpoint, the answer to your problem lies in four words in your question: "he won't let us." Many times, people with small dogs tend to think of them somewhat as dolls, not needing the training and discipline so obviously included in a larger dog's upbringing. I ask you to think about this: how big is he, and how big are you? And he is calling the shots here! I would suggest that you NOT pick him up in the normal course of your lives. Don't try to make a "purse pooch" out of him. A beginner obedience class may help you to understand how to relate to him as your dog and not your equal or superior! The instructor will be able to teach you how to deal with his attitude and help you to get from him the kind of behavior you are looking for.
