After having a yorkie with liver shunt and to watch him go through all the pain of surgery and then having to put him down after 4 short years...I have the bile acid test on all of mine...it might be more money, but trust me its worth it....:) |

The urine bile acid test has been known to not be as accurate as it does not give numbers. |
I'm all for it as well! I really want my Gemma tested but I don't want to go through it myself! LOL! I'm afraid to fast her and I don't want that on my head! I am still looking into the recommended urine bile acid test though. I would much rather pay more to know the breeder was already able to rule this out! |
Thanks for all the info...I want to be prepared for Winston's vet visit. |
All the test proves when given is that the pup at that point in time dose not have a liver problem but most shunt dogs develope it after a year old..So the big Guarantee means nothing for one yrs period of time of a guarantee. It's a line problem genetics as the lines with the heavy shunt problem back in the early 90's was the Rothby line.. Beautiful dogs but many died because of it. They had some of the most saut after dogs and used many in breeding to get that look and line bred and inbred to get it there fore doubling or tripling the chances of it developing in the off spring..Unverity of Davis did a huge artical in the Yorkshire Mag on it.. |
1 Attachment(s) Attachment 123641The liver shunt test only tells you the pup at that point in time in it's life dose not have a liver problem.. Most shunt dogs develope it after one yr. Back in the early 90's Yorkshire Mag had a huge write up as to the dogs dying of Shunt's and the line it was showing up in large numbers was the Rothby line. Then when closely bred making the problem even worse till they figured out what was going on.. Shunt can happen in any dogs but with so many breeding the Rothby line into there dogs had some bad problems with longevity and with out surgery they died. Would I buy a pup with out the shunt test.. Yes.. as if that's the only Guarantee they have it's not worth the paper it's written on. A better guarantee is replacing a pup if a genetic falut causes early death proven by vet documentations. |
Very helpful information, thanks!!! |
I agree... the 100 addition cost is nothing compared to what costs are involved if the puppy does have LS. JMO |
There has been a lot more research since the 90's. Rothby is far from the only line with shunts. The more they check pedigrees the wider the bloodlines are getting. The worry is that its in so many lines it will be very hard to stop. The duct should be closed by the time a pup is 6 weeks old. Testing can be done at 10 weeks. Most acquired shunts are inside the liver, more of an MVD type and caused usually by other health issues. I do advise the Urine Bile Acid tests because they are accurate and there are few or no false positives and no fasting. You should feed the pup 4-6 hours before getting the urine. Its 100% sensitive to liver function. Its a screening tool as is the blood bile acid so if it's positive further testing would be required. But its a sure sign not to buy the pup if its positive. |

With the prevalence of liver shunts in yorkies, I would definately spend the extra money for a peace of mind that your yorkies does NOT have a liver shunt. |

Most (not all) of the shunts that are seen in yorkies are congenital...meaning that they were born with it, so it doesn't just develop after one yr of age all of a sudden. After a yr of age might be when you notice the symptoms, but dogs who have congenital shunts are born with it. If anyone wants further information on this topic, you can go to the UT's website and read the information provided by Dr. Karen Tobias, a top vet that specializes in liver shunts/mvd or you can join the liver shunt/mvd group on yahoo groups. They have a very extensive file section with info from many of the top vets. |
