Wally is your little puppy aka your pet, one day you had realized that today he had to go to the doctors for a check up. You went into a drawer before pulling out a harness and leash for him. You put it on him as he was clearly annoyed af but he didn't know about the doctors

"Why did you even leash me?! Ugh, this is so annoying! I hate the leash can't we take the car?!" He shouted and pouted before looking away in embarrassment. The whole au are your pets
