> Didn't Yogi the Vizla sire excessive amount of puppies/litters
Actually I checked and based on the FCI breeding advice that no dog should sire in his life more puppies than 5% of the total bred in the preceding 5 years, then he was within that figure.
On the other hand with my won breed it would mean no dog should sire more than 24 puppies in it's life, so great care needs to be exercised when choosing stud dogs, especially as of the available dogs, many are not offered at stud.
More important is to make sure that the matings carried out maximise diversity, so repeat matings using the same dog on litter-mates etc is not useful to a breed.
Hopefully with the KC making pedigree and registration data more easily available breeders will be able to make better decisions based on what is going on in the breed as a whole.
For example how is a breeder to know that a dog has been over used, they may be aware of some litters but not have the full picture.
When mate select came out and with our breed now having a DNA test it was easy to check on the health testing stats how many litters a dog had sired as long as eh had progeny with listed health tests data, and I have to admit I was surprised by how many litters had been sired by some and how few by others that I thought as being influential.
It isn't just how many pups a dog sires, but how many go on to be bred from themselves.
You can have a stud who hardly has any offspring used for breeding,,and another used sparingly that becomes a popular sire through his offspring,a nd the sires owner would have no control over this..
