Maybe a Hybrid

This little black dog was very young, so tiny that its features were hard to see. At first, it looked like a normal dog with no special markings. But looking closer at its face, David started to wonder if it was a mix of two breeds. Its features were a bit different from a typical puppy, and this idea intrigued him. He could not explain its unusual look, which only made him more curious.
The oddness of this animal made David think it might be a hybrid. This thought pushed him to find out more about its origins.
