Breeding, to me is a serious issue that needs to be well thought out.
Breeding is not the least expensive way to add to the dogs in your kennel. You have the expense of looking after the mother, raising the puppies (food, vaccinations, added veterinary expenses if there are complications, every day interaction with them for socialization and at least two years of maturity to see if the puppies will actually fit in your team.
Then if there are puppies that don't fit, finding them good homes.
The least expensive way to improve your kennel is to purchase a dog or dogs from a good musher that is excelling in the races and/or has a good reputation for producing high caliber athletes.
If you are just starting out to build your kennel, I would suggest to purchase a well bred female, a retired leader preferably.
Check out the pedigree, if possible see the dog running in a team, check out the other offsprings and their performance characteristics. Don't be afraid to ask the musher about both the positives and negatives of the dog.
NO DOG IS PERFECT! The same as humans.
The reason for purchasing a female is it is much easier to find a suitable stud for breeding. Also, if she is a Leader, then you have a good experienced leader for training the puppies.
Breeding is a science and requires effort in analyzing pedigrees to ensure the best possible results in the puppies.
I personally, like a pedigree that is Line Bred on both the male and female side. Check to see the number of Leaders in the pedigrees. Although there is no guarantee the offsprings will be leaders, your chances are greatly improved there will be some.
You can never have enough Leaders!
If you build your kennel around dogs that are related, you have a better chance that their performance will be simulare ( body conformation, running stride and attitude).
Whether purchasing a dog or breeding, you should ask the question; " Will this improve my team"!
I have had the great fortune to work with top mushers that helped me to develop a kennel of Canine Athletes that suits me.
My last breeding produce six Supper Athletes and with two leaders for sure and a possible two more.
Breeding is a serious endeavor and should be well thought out!
Until next week........
