picking the right dog

so this breeding stuff is not as easy as it looks I am trying very hard to find the perfect dog for each of my girls. I think that when I call a prospective stud dog owner, I have a pretty good package. My dogs are ch, with all of their health clearances. I have done my homework and by the time I have reached out to the owner of the stud dog I expect for them to be happy to work with me. That does not always happen. Sometimes for whatever reason the answer is no. I am always a bit shocked but it happens Now on to the next choice. This is not easy
