Just a few days and you won't even realize he had surgery! I'm sure it's different for boys [never had any experience with neutering] ... but for Toto the main thing was the stitches. Had to be careful about her jumping up and tearing the stitches or getting them inflamed. She did great ... got stitches out in 10 days! Glad Mickey is OK and on the road to recovery!! Puppy kisses from Toto!
