No experience but some knowledge. It seems like most of them get along fine. There is a large variation in amounts of bowing in dogs considered to have CD. Some never experience any ill effects from it. TAMU is currently working on a grading system but nothing out yet.
If you look at some of the pictures of the dogs that Dorothy Goodale started with you will see some bowed legs. This doesn't mean that there is no CD behind Havanese coming out of Europe. Dogs went from here to Sweden and different places on their way where they are coming from now. A group even went to Hungary looking for DNA different than the Goodale dogs lines and didn't find any. Another group went to Cuba and got some DNA but I haven't heard any results from that yet.
A few years ago it was estimated that 1/3 of all Havanese had CD based on: a survey, what judges who knew the difference said, and people like Pam and Diane have said(who have probably had their hands on more Havanese than anyone else(and know what they are looking at).
Most people simply didn't and don't know the difference. One of the first Havanese to be put up in one of the TV shows after we joined the AKC was a CD dog-the judge said he was the only one in the ring with "short legs" which the short standard from AKC called for at that time.
During the Havanese 100 Study, owners of the dogs in the study were asked to take soaped pictures of their dogs with the hair plastered down with wet soap. Among other things, the front legs were to be compared. This was when a lot of Havanese people first started "soaping" dogs. Margie wrote a good article in the current issue of the Hotline on how to take soaped pictures. I took the 2 pictures in the Hotline with the front leg views while Pam stacked the dogs. We do that with all our dogs and puppies.
Most responsible breeders have pulled the dogs with bowed legs from their breeding program. I don't believe anyone on the HCA recommended breeder list is breeding CD dogs now. At least I hope not.
There is a synopsis of the Heart Study also in the current Hotline for those that haven't kept up with it and are interested in the part that CD plays.
But CD is back there in just about every pedigree there is and the mode of inheritance has not been determined. Two straight legged dogs can be bred and produce a CD dog.
One of the reasons we only will ever breed a female that goes back tail-female to our Twinkle is that none of those females have ever produced a single bowed leg. But we have only bred to a couple of outside males. One of our males, who now also all go back tail-female to Twinkle, did produce one bowed leg but that was out of an outside female, that I will not name, whose line has had some problems-so it's not something that can be "fixed" as might be claimed by a stud owner.
There is no sure answer to only breeding correct dogs yet. Breeders just have to do the best they can which involves a lot more than just putting two dogs together. Unfortunately, as much health testing as is done by the best breeders there is no final answer even with all the time, money, and effort being put into it.
