Language is fluid; it is ever-evolving. It’s okay to make changes to grammar when the times and attitudes progress.
It's time to stop calling animals "it."
The Current AP Stylebook tells us: "Do not apply a personal pronoun to an animal unless its sex has been established or the animal has a name.” Extrapolate that to mean a dog named Harry is a “he”, a mare (female horse) is a “she” and a wild turkey is an “it.”
NO animals should ever be called "it."
