Paige, I'm so sorry to hear about Preston! I sure hope the vet finds it to be a mild case and hopefully won't affect him. Please keep us posted.
Doggie Nut, Here's a nice website explaining many different health issues that can affect our havanese.
"I have chosen to provide some information about Chondrodysplasia, which basically means premature
closure of the growth plate. When this happens, the bone continues to grow some, causing it to grow
at a bowed direction away from the 'wrist'. It most likely causes asymmetry of the two legs also.
If you soap up the dog and look at the inside of the legs and chest wall, you may see one side of the
chest wall 'higher' than the other side. Or you may also see one or both legs (from the 'wrist') bowing out a bit.
Chondrodysplasia or 'CD' is seen in many breeds of dogs, and interestingly enough is the fact
that those same breeds share eye problems much like the Havanese do."
