Dear big boy dog - I know the new little dog is annoying, but she is still little. Please wait until she is bigger than your mouth before you try to bite her. Thanks.

Dear big girl dog - Thanks for being such a patient and understanding puppy-sitter. I could not have asked for better behavior from a big sister. You truly are a wonder.

Dear little dog - Why is it that you can learn from the big dogs how to play, how to behave for treats, how to ask for dinner, how to 'kill the squeek' in a toy, how to use the dog door, how to NOT chase the ducks and how to sleep quietly when the humans are in bed...but you cannot figure out that peeing happens OUTSIDE (and not just inside) the dog door? Is it something we are doing? If so, give us a clue. Thanks.
