Welcome to YT from a fellow Marylander
We live about 5 minutes from Columbia
Your babies are adorable.
I wanted to tell you a couple of things in reference to pet stores and breeding. I did not know this when I got Georgie but because of the amazing people here I learned to never buy from a Pet Store. Most if not all get their puppies from Puppy Mills which have deplorable conditions they don't care about the dogs and many end up with health problems....since they aren't taking care properly from birth.
As far as breeding no one can tell you what to do but I would suggest that you don't breed. There are so many things that can happen when you breed with the female and judging by your post I know you love them a lot and wouldn't want anything to happen to them.
If you still feel the urge to breed I suggest you check out the breeding section of YT and ask a lot of questions. Also, please do not breed your female if she is less then 5lbs.
Again, welcome and I look forward to more pics of your babies.
