Dr Jean Dodds was a major contributor to this list.
Please note that there are 32 conditions listed on Yorkshire Terrier of which Lacrimal Gland Aplasia is one. |
I just wanted to add that all the eye conditions that do come up, such as ingrown eyelashes, eyelid problems and cataract, in fact everything to do with the eye, is either ruled out or in, by an opthamologists' examination, and the results are posted on
www.cerf.org. Also note that this organization recommends passing examination at 1yr old and I believe yearly thereafter. A cataract that is diagnosed prior to 6yrs old is referred to as juvenile cataracts and is thought to be inheritable although the actual genetic marker is not known at this time. That is why eye examinations need to be done frequently if you are breeding dogs.
To be clear about the meaning of this you can breed a clear dog at 2yrs old as shown by cerf, but later on 1 or more years later that dog can be diagnosed with a cataract.
