This is a great place for research. I think you sound like you want to breed ASAP and you have just started your research???? I had my FIRST litter early this morn. I have been researching for over 7 years already. I hope that if you really want to breed that you are not in a hurry. My poor mentor was up all nite with me, she is great. I think you really need to find a mentor in part of your research. I had a lot of experiences with this litter. 1- we had a huge litter of 6, I am always watching to make sure each pup is eating and mom is able to take care of them all, there is a pretty good chance I will not be getting much sleep for a long time. first pup came out with a green placenta (o crap, right off the bat huge worry) then we had 2 comming at the same time and breech (had the vet on the phone at that time and ready to go at 3:47 this morn) just a lil of my all nite experience, not to mention the cost of all the testing I have done, a lot of expense and a TON of worry. Sorry I babble
If you are serious about breeding please don't be in a hurry is the point I am trying to make

and be ready for a lot of cost with money and worry.
Find a good and supportive VET before you start also. (one familer with small breeds) A great vet relationship is also important.
