* Anatomical incompatibility: Dogs and humans are different species with drastically different reproductive systems. Their genitals are structured in a way that makes mating physically impossible.
* Size difference: The size difference between a dog and a human makes any kind of penetration impossible.

Please remember that it's crucial to treat all living beings with respect and avoid engaging in or promoting harmful misinformation.
