So, maybe all dogs go to hell.
Which would actually be much more logical, since:
- all of creation is fallen,
- thus dogs are fallen
- Heaven is only attainable through sacramental grace.
- Dogs are not baptized
- Therefore, dogs don't receive sacramental grace,
- Thus, if dogs have souls, their souls must be fallen (along with the rest of creation), they have no baptism to save them, and thus no means to be healed of their fallen state.
CONCLUSION: All dogs go to hell.
Either accept that conclusion or stop pretending pets are persons. Pets don't have immortal souls - they die, they are done. They disappear. Period. End of story.
