Hi, thanks for using PetCoach! Poor Betsy! She is very cute! Hormones from pregnancy and lactation can affect the skin and hair. If the puppies are all weaned and have new homes, then I would suggest full blood work. Low thyroid and Cushing's disease can cause thin hair coats and pigment changes in the skin. Starting an Omega 3 fish oil (http://vrshealth.com/canine-products/omegadog/) won't hurt. Be sure she is on a good balanced commercial diet and if she is still nursing be sure it is puppy food. She should also be dewormed, pregnancy and nursing activates "sleeping" round worms. Parasites can cause a dull, thin hair coat. I also suggest having Betsy spayed. At 7 years old I worry about being intact impacting her health (pyometra, mammary cancer) and that is a bit old to have puppies again. I hope this helps and I wish Betsy the very best!
