My husband and I were having a conversation about breeding following the huge increase during the pandemic. We were talking about how a lot of breeding has taken place without health testing and careful selection of a sire that compliments a bitch. As members know, Luna is spayed so this is not a question in planning to breed from her just a question that came up out of interest from our discussion. How does a breeder select a sire that is suitable for their bitch (assuming they are the same breed). Aside from the obvious correct health testing, temperament, performance in e.g a working dog, size of sire in relation to dam. Would they choose a sire with as similar features as possible e.g head shape, body formation - as near to the breed standard as the dam? We wondered if a sire might be chosen with stronger features so that these may be present in the puppies but then I thought if the bitch didn't have strong features of the breed standard, she would not have been chosen to breed from. I know there is the coefficient (is it called?). Is this to make sure they are not too closely related to the bloodline of the site? It is very interesting.
