I hope Cash is OK.Peanut got fixed on April 11, 2006. After two days we noticed he was red down there. Took him back and they put a collar on him.Vet said to keep it on him for 10days. I said Peanut is a very Hyper dog. So the Vet said OK only for another week. They didnt charged me for the office visit or the collar. It was a re-check so no charge for visit. You can get the collars at Petsmart or Petco. Hugs and kisses from Peanut and Thumper!
