React hooks - setState does not update state properties

I've made it to the useEffects
portion of the course. When implementing useEffect()
I am not seeing the values of animal
, location
or breed
passed to the url here
I added a console.log in the code below and the value of animal is always empty
async function requestPets() {
console.log(`animal=${animal}`)
const url = `http://pets-v2.dev-apis.com/pets?animal=${animal}&location=${location}&breed=${breed}`
console.log(url)
const res = await fetch(url);
const json = await res.json();
setPets(json.pets);
}
I am using
npm 7.15.1
node v16.3.0
What am I doing wrong?

Passing animal
to useEffect()
allows it to populate correctly but I would love to know how to update only when you hit the submit button.
useEffect(() => {
requestPets();
}, [animal]) //eslint-disable-line react-hooks/exhaustive-deps
