Our first experience with VPI was with our Yellow Lab, Traveler... He had ACL surgery 3 times, then was diagnosed with Larangeal Paralysis. He had the tie-back surgery. And had several bouts of pneumonia. VPI was a godsend... Our next was with Hunter, at 11 months he bacame ill. After several days of hospitalization and surgery, we unfortunately lost him. VPI again was great, all the way throught the (2) autopsies... We nos have it on our current dog Keeper...
