I'm not particularly sure if this is accurate, but from personal experience I would say the size of either parent does not guarantee that you will have smaller or larger babies.

My Yorkshire terrier, Dexter, had a mother that weighed seven pounds and a father that weighed four pounds. The Grandparents both weighed under seven pounds as well. However, my puppy Dexter weighs almost ten pounds fully grown. I've met plenty of people who had a line of smaller Yorkies bred that still gave birth to larger pups. There is a lot more to breeding than just the physical size of the parents, but the genetics they are carrying for the potential of small and large puppies.

Again, I am not a breeder... so I don't really know!! But I do know that there are a bunch of wonderful knowledgeable people here that will have an excellent answer for you!
