We just got Simba (5 months) neutered last Thursday. When we picked him up from the vet office in the afternoon, around 6pm. He looked like nothing happened. He didn't lick too much at the vet, so they didn't give him the e-collar. The vet told us not to let him jump up and off the couch or bed, running, rough play and watch him not to lick and give him a medicine the next morning (either pain killer or antibiotic). I didn't walk him for couple days and of course no dog park last week. He did whine a little during the first two days, but everything else was just fine. He sometimes licks it and will stop if I tell him to. We didn't give him bathe last week either.
He did poop in our bedroom on the first night home... Usually he would wake us up.
I think Simba losses some energy after the surgery. He still likes to play, but he sleeps through the night now
Your little cutie Brody will do just fine
