In most clinics and hospitals, dropping your dog off in the morning for his spay/neuter procedure means you will have your pup back that afternoon or evening — so you only need to be apart for a few hours.
“Most animals, with a round of anesthesia that lasts approximately 15 to 20 minutes, will be ready to go home and act quite normally six to seven hours after,” Lund tells The Dodo. “They might be a bit groggy or in some discomfort, but for the most part, a lot of dogs will act like themselves in a more subdued manner.”
Anesthesia monitoring is taken very seriously, and your vet will ensure that your dog’s heart and respiratory systems are doing well during the procedure. Directly after surgery, your pup will be closely watched by the vet or vet tech for a half hour to make sure they wake up appropriately, Lund explains.
