When it comes to a needless decision like this. Dont listen to a vet.

I can only assume this "procedure" is expensive. Which = money for the vet.
MOST(i said MOST not all) vets loose sight in ethics and morals when they get all the money. Its a proven fact ya know. Vets dont know EVERYTHING about dogs. They Dont know everything that is good for dogs. Most do not study how things effect them emotionally, they look only at if it will take a long time for them to heal. Sorry kid, but your vet dont givva damn what happens to your dog. If he did, he wouldnt recommend it, and if he DOES care anything about you or your dog, he doesnt know anything about how it emottionally scars them ..
I mean, ask anyvet what to feed, and im sure youll get the same crappy response. hills science or iams. Ick
