even though must sledding dogs aren't registered with AKC or similar registries, they still have family trees. You have to do a LOT of research to learn those.
For the labs, are you going to breed field labs? I can tell you what people will want to see there. They are going to want to see real life hunting experience - doubt you are going to be going out bird hunting every weekend? They are going to want to see hips, elbows and eyes. They are going to want to see hunt test titles. They are going to want to see all of these tests -

They are going to want to see that you know the dogs pedigrees inside and out. You will need to know exactly what you will produce as far as drives when you breed Dog A to Dog B. They will want to know why you chose to breed Dog A to Dog B. The fact that you own both mom and dad? They are going to view that as a huge caution flag. Having two different breeds? They are going to view that as an even bigger caution flag.
Having just one breed and doing all of the work and testing that goes into it is practically a full-time job squished into a hobby. Having two breeds that have such different jobs? Nigh impossible. Now, if you had two similar breeds - 2 breeds of bird dogs then it might be more manageable. The same trial will work for both breeds though it automatically means twice the entry fees.
For one title on one dog, you are looking at several thousand dollars invested.
These prices will vary depending on your area:

They also don't include the cost of proving the dogs. If you are going to have 3 dogs of each breed, you are looking at an easy $20K before you can think of starting breeding. That doesn't include the cost of purchasing your dogs. The cost of building your facilities. The cost of vet care on those dogs. The expenses with having license fees etc. Also, since it sounds like you will be shipping puppies (not a lot of mushers in KS), you are going to fall under the USDA guidelines. Those carry very specific ways that the dogs must be housed and separate facilities for moms with pups.
I've been in GSDs for 10 years. I've been researching the pedigree of my current boy for 3. I've been working him since 6 months old. Just in this one dog I have several thousands invested and I'm a lucky one. My local kennel club has given me the ability to get most of my training classes at no charge. If I had to pay for training, I would have passed $10K a long time ago.
