flat nipples on female yorkie pup

Question
Hi,
I have been breeding Yorkies for about 8 years now.  I have a 4 1/2 month old 4 1/2 pound female that I kept back to be a breeder.  I noticed that her nipples are very tiny almost look like freckles.  I was wondering if you have ever experienced this before, and if you think that this could cause a problem when she had puppies? She has not had her first heat cycle yet.

Thank You,

Amanda

Answer
Amanda,

Hello fellow breeder!  I do not think you have anything to worry about.  Since she is only 4.5 months old she still has plenty of growing to do.  Her nipples will grow larger after she has her first heat.  In the past I have had adult females with nipples that were small and appeared almost flat but they never had any problem feeding their puppies.
