The shant is on the outside the liver and this is good Dudley will have his surgery tomorrow and they should know tomorrow how it turned out. He was doing pretty good over the weekend the medicine he was on is working and he was playing and running all over! My dil said he was almost 100% back to himself. Dudley weights 7 pounds and the Vet there at KSU was happy to see this she said they have done this surgery on 1-2 pound Yorkshire puppies and they are really small!
