I would cull if there was a real noticable problem in the pups health when born even if they had reached 8 weeks and they couldnt walk properly I would cull. I do sell pet quality pups if there is no real problem with the pup other than not being typical for showing but with the changes in the breed standard recently what was under the old rules as ok maybe wont be any more so it is upto breeders to adjust which dog is put with which and see from those breedings whether the new pups conform to the new standard. Many will continue to breed the very wrinkly dogs because people attitude will take time to change and to cull before a number of shows over a number of years show us what is expected it seems pointless to just cull because of the confusion of the standard. Many people including myself do contracts and if sold as pet quality, you are unable to breed because our new rules in this state does not allow breedings of pet quality pups. One you cannot register and two many vets will not encourage this and the council are now giving out heavy fines when caught. People need to work together but also set their own standard of whether to cull or not within their own breeding and be able to choose which way to go without others (no one has the same ideals) and what is satisfactory for some is not necessarily good for others. I am quite happy when breeding two new dogs together to keep all pups from a breeding if I want to make sure they are what I was aiming for in the first place. I wouldnt breed unless I was prepared to do this. And would cull if and when necessary.
