U can walk her only a little initially to let her pee or pass out poop ,and then gradually increase exercise as healing progresses ,you must not let her jump over or run till the surgical wound heals completely,do dressings and give antibiotics and painkillers as advised .avoid licking and biting or scratching with paws by dog to avoid self inflicted injury .that's it and in ten days to two weeks your dog will be raring to go back to her usual self
