I hate to say this, but it sounds as if your so-called breeding program is just what they are doing in some other countries. It's basically nothing more than back yard breeding to raise some money.
There is so much more to breeding than just putting two dogs together. You need to read all the stickies at the top of the Breeding forum. I don't know what type of health testing is done over there and I would wonder if you had hip and elbow prelim's done on the dogs you are import in to your country prior to having purchased them. The dogs you are importing are old enough to have been tested and certified against eye and heart problems. Has this been done?
**What DO the breeders in your country test for in terms of health?
**At what age do you start breeding dogs in your country?
**What type of dog shows do you go to over there? What do you compete in?
**If you have to even ask questions on how often to breed your bitches, then you are not ready to be a breeder.
**How do you even know that the pedigrees on the dogs you have purchased will be compatible? What type of research have you done on them?
**Are the sires and dams of the dogs you are importing titled?
**What type of health certifications do they have?
If you don't show your dogs to earn titles to indicate that they adhere to the breed standard and if you don't do health certifications on your dogs to make sure they are not carriers of HD, ED, heart and/or eye diseases and problems, then you are not an ethical breeder.
Please find a mentor, take a few years to educate yourself, go to tons of shows and learn about structure and THEN evaluate your dogs to see if they are compatible and qualified to be bred.
Edited: I see in some other posts that you already have imported a few dogs and have a new puppy. Exactly how many dogs do you have and what are you long-term plans for them? You are asking a lot of questions about breeding, but don't even know how to crate train your puppy. What is going to happen when you have a dozen puppies at once?
And read this post about keeing two bitches together.....it can be done, but very often it is a disaster waiting to happen if the owners are not educated Rottweiler people and know the warning signs of impending difficulties between the two bitches.
