Do the Crooked legs (CD) appear more with bigger Havanese? and other health issues?

Our Coco was 11 years old when he passed away and weighed a trim 21 lbs. He had bowed legs, with one that turned out sideways. That did not hampered him at all and no Vet worried about it. What was a problem was his health issues. He was atypical Addison's, had bladder stones and died of Lymphoma. We loved his size and would want a larger Havanese but worry if this health problem is a trend in larger Havanese. We do not want to show or breed and would not have traded our time with Coco for the world. We just are doing more homework this time.

I just read about this study at this web page which I will add here. Does anyone know about this study or have further information on this subject?
------------------------------------
If you are a breeder, I hope this page has provided you with some food for thought, education and hope for the future. If you are a puppy buyer, I hope the information here, will enable you to be more educated about the Havanese breed and help you to be able to chose your breeder
and future puppy more carefully. Again, not all CD dogs have health problems
but too many of them do. Like any syndrome or disease, it can very well carry with it
other problems besides just the bone deformity.

How can you help?

Keith Murphy and his team at Texas A&M University (TAMU) are underway in an important study. We need to raise $200,000 to fund this research. If you own a Havanese or breed Havanese, then please help! There are two ways to financially help.

1. Join "Friends of HEART" at http://www.havanese.net/heart/default.htm

2. Buy "The Havanese" by Diane Klumb at: www.lulu.com. All proceeds to this wonderful book are donated by Diane to the TAMU project!

I think that study is about 8 years old now. The location of the different genes they found for CD was later validated by a couple of other studies a few years later, that were more specific in finding the exact genes that produce it, but those later studies found the exact genes, at the same location on the same chromosome as the TAMU study just found as a cluster of different genes in dogs with CD and dogs without symptoms. remember it very well.

Dogs with larger bones do have more curvature than fine boned dogs, just because of the way the bones work together. C D is obvious though, and not this normal curvature in heavier boned do

I know about the studies in pretty good detail. t c aused a nasty split in the breed-the second such split. There are still many in denial, in spite of current s cience[/I]

CD is a caused by a double insert of a parti cular gene -FGF4, that pushes some c lose to that loc us out of their ideal position, so it's kind of a crapshoot what c omes out of it as a result. With current sc ienc e, a genetic test could be developed, and it eliminated from the bnreed in a couple of generations, but there are still a lot of people in denial.


Google FGF4 gene dogs, and you should find lots more information

Is this crooked leg gene tied to other health problems?

Thank you Tom for this info. I guess the bigger Havaneses and the breed standard both have these legs. But I wonder if a dog is deemed by the breeder to be ""limited" and not for show, are they higher risk for the health problems?? I love the Havanese, but I am trying to figure out my best chances for a healthy one. Coco was such a great dog but his health problems almost did us in.

Breed Standard calls for straight legs.

Limited does not mean that the dog could have health problems. It just means that the breeder isnt selling it to a show home.
