Sarah combed the bitch's fur getting the tangles from it. The grooming felt so good that you sit there contently, slowly wagging your tail. With your fur groomed she fastens a leash to your collar and you hop to your feet excited.
You have a vague sense of who you were, but it is overwhelmed but the feeling of freedom. You run around with your Mistress back and forth smelling the trees until you feel an urge. You stop suddenly as the need to release your bladder temporarily restored your mind. As you are squatting releasing yourself on the lawn, you definitely realize something is wrong - not only the fact that you are a canine, but that you are not lifting your leg. You lower your head slightly and your nose somehow registers a thought in your brain that you are in heat.
You look around wondering if you can escape when another scent catches your nose. You look around and stand there in fear as approaching your area, you see.
