My scottish terrier is a female, and turned one year old last month. Her mom only has 1 litter of puppies every other year(thats what the breeder said). My dog's litter had a rare 8 puppies in it. She was the smallest of the 3 of them left when we adopted her,and her back kind of slants forward. Is this normal? If not what is wrong? She loves to run, and is very entergetic. I <3 her soooooo much!!!
