2005 Dec Bumbie playing ball.jpgThe 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.
