Having a c section and not breast feeding does not make you less of a mother, your body any less strong or your womanhood any less powerful.
It will be months before you do anything for yourself. Baby comes first, husband second. You fit in somewhere between the dog and the grandparents. But somehow you're ok with that. A happy family helps you to be happy.
It's ok to admit that you are having a hard time and need help. You are not super mom. You cannot do it all, all day, everyday. Give the baby to your husband. Let the dirty dishes sit another day. Breathe.
Start exercising now. You'll miss your old body and starting a new exercise routine with a newborn is a daunting task. Plus, your baby will be a giant that loves to be held and you need all the strength you can get.
In the same vein, let yourself recover in your own time. You just had major surgery. Let your body heal. Don't push it. Pushing yourself will only hurt you more.
Spend time with Sadie. She is a sweet pup and will be a great big sister. Love on her extra while she is still the only baby.
Don't bother reading all of those parenting books. As soon as you bring the baby home, it all flies out the window and you will know nothing. Your baby is special and none of those techniques will work for him anyway.
You will spend most your days in pajamas, covered in at least one bodily fluid. Make peace with this idea now. You don't get to be grossed out as a mother.
Going anywhere will require at least an extra hour of prep now. Pick and plan your trips wisely. You will learn to fly through Kroger in 30 minutes or less and be very proud of this skill.
Your heart will grow twice as big the moment you meet your baby. And it won't ever stop. You will love you baby more and more every day. He will give you a perspective on life you could have never imagined. He will become your everything. He will make you a better person. He will make you whole.
