You just sit still inside of its belly. You figured that being dog food wasn't that bad. You decided to just enjoy the time you spent inside. The walls rocked around, splashing digestive fluids onto your clothes and exposed skin. Your shirt and shorts are forming tears from being digested, exposing your underwear. After spending some more time inside, your shirt and shorts are completely digested, leaving you in your underwear. Overall, your body feels pretty soft and weak at this point. You just stay calm and let the acids work on you, soon making you completely naked since your underwear gets digested off. A good while later, the dog finishes digesting you.
