"I'm dog food." you said.
"What?" she responded.
"I'm dog food," you said, "let your dog eat me."
"If that's what you want." said Annabelle, "Come on, Red, here's your lunch."
You strip yourself down and then walk over to the dog. You present your head to the animal and it opens its mouth wide over your head. Your body is slowly sucked in and is making its way toward the animal's throat. You try to ignore the smell as the dog slurps your body. Your shoulders squeeze in easily and then your chest and sides make it in. After that the dog swallows your stomach and moves toward your hips. Most of your upper body reaches its stomach and you wiggle yourself in further to help yourself get settled. Before you know it, you're completely inside.
Now you're dog food. You figure that Annabelle doesn't have anything to say to you, since now you need to fill your role as her pet's lunch. You relax and enjoy the feeling of its stomach as it digests you. Your naked body slowly melts away in the dog's stomach acid and the dog is satisfied with its willing meal. Eventually, the two of them forget about you. After all, you ended up only being good as dog food and nothing more.
