| Leggs-Perth,Patella,trachea testing From the Yorkshire Terrier Club of America website optional testing, reading books, and postings here on YT I'm concerned about these three crippling diseases and wanted to get my yorkie tested. I'd like to get some advice before asking my vet, since I've only been to her once and may send me to a ton of specialists. I'm posting this thread here to get advice from breeders/non-breeders who test there dogs for these diseases. To limit a dog to radiation from x-rays can all three of theses be checked from one x-ray from one specialist? If so what kind of specialist? Any advice would be greatly appreciated...Thank You |

| Knee caps can easily be checked without xrays by your vet...they may be perfect at 12 weeks and not at 12 months... There is nothing you can do to prevent or even know if your Yorkie will have the other two problems..no genetic tests. You must buy from a reputable breeder who has done all they can to perfect their breeding program to eliminate these problems... bad things happen to good breeders..so you must have a breeder who gives a health guarantee... BUT...I would never promise a life time of good knees or trachea..those can come from injury and aging...Legg Calve Perthes is different...I have never had it so I would guarantee a puppy. |

| We just had x-rays done on Kayla to confirm CT. They can tell how much damage has been done. Kayla's is kinda at the base of the neck and not bad yet, but has had several bad attacks from it. We now have her on a diet. She is on OM, a prescription dog food to help her lose weight. Weight is really important with CT and just about the only thing you can do. I wish they could learn more about it and I hope she never has to have the surgery but other than that, weight management is about all we can do for them. |

| Are there genetic tests for CT and Legg calve Perthes? You know I have not had a Yorkie with trachea problem in 25 yrs..so forgive me for thinking it was not detectable by xray...but I find it hard to believe a breeder could xray 12 week olds and detect a problem coming in the future unless the pup has symtoms...just never seen a young pup with these problems... |

| CT can be seen on xray, but not always. Fluoroscopy would be needed if you wanted a more definitive answer. That wouldn't be something you'd do with an asymptomatic dog though. I don't know of any genetic testing for it. LP, as YorkieRose said, doesn't require xrays to diagnose. They can try to grade the disease this way, but vets can tell by palpation whether or not it is present. LCP - not so sure. I'd think an xray would show it, but don't know of genetic testing for it. It's not nearly as common as LP. I wouldn't worry about it unelss you are noting hips issues in your pup. Because different contrasts are required for different parts of the body, it is doubtful that a vet could get a good look at the trachea and hips at the same time. I wouldn't be too anxious to look into any of this unless you are seeing symptoms (or unless you are breeding of course).

| The Yorkshire Club of America suggests that testing be done, mandatory for Patella Luxation and CERF. Optional testing suggests Leggs-Perth, Thyroid, Cornell DNA????, and Hip Dysplasia. CERF has to do with eyes if I'm not mistaken, a thyroid panel is done?...I think and Leggs-Perth,Hip Dysplasia,Patella Luxation,Trachea are checked through x-rays, I think. That's my question. Does one have to go to different specialists to have these tests done or can one x-ray be taken to cover all four? I have no clue what Cornell DNA is. |

| I'm sorry I wasn't more clear but I have a three year old female that I was considering breeding but want a clear bill of health. I have bred before but with a totally different breed. Thanks again. |

| I know we have a little schnauzer that her hip will go out of place and right back in and with our little Dudley (yorkie) the vet has felt his go out. The thing with that too is to try to keep the weight from going up. Kayla was having symptoms that we kinda knew ahead of time she had CT. From what I understand, it is not genetic and they really don't know alot about it. Its a horrible disease and we are trying to get her back down to 5lbs. We just wanted the x-ray to see how bad it was and what we were dealing with. She had a spell at the vets and her temp. hit 106. We really thought we were going to lose her. That is stroke stage and I was scared to death. What I understand is that all toy breeds can have it not just the yorkies. |

Cornell DNA testing go to their site and they will tell you how to submit and what to do to get your dog's DNA profile done and then it can be submitted to AKC. LEGGS Perthe and Hip dysplasia, you need at least two Xrays probably four. There is a specific positioning needed to assess the hips for dysplasia. Each hip is Xrayed separately and different views are needed for Leggs Perthes. Usually there are specialized clinics that offer OFA testing, or some AKC shows will have health clinics where you can book an appointment and go there to have your dog tested. Patella Luxation examination test results are clinician submitted. Generally through palpation alone. CT I have never tested for, only checked the health lines for.

| I would want to know the history of the line and the line you will be breeding with...and then watch for Mother Nature to throw a curve ball when she pleases. Do the test the vets suggests are needed. Best wishes I learned very quickly what lines to avoid for serious health issues... |

| She has a lot of Durrer's in her pedigree, so I think that would be a good starting point. |
