In Portuguese (or Latin languages) if the animal is female, its a she.

Even inanimate objects (“You are a fuc### inanimate object!”) have gender. Not all.
Why or how, I don’t know.

But a I know all chairs are female for example.

“Esta cadeira é desconfortável.” - right.
“Este cadeiro é desconfortável.” - wrong

“This chair is uncomfortable.”

“O” at the end of a word is male and “a” is female.

And “this” on the female version has an “a” at the end “Esta cadeira”,
but male has the “e” “Este cadeiro.”

Yes. One has a problem of being called dipshit…the other is one.
