One solution

Good afternoon My solution is a bit different. What do you think about it?

const selectAnimal = document.getElementById("animals");
const selectBreed = document.getElementById("breeds");
const options = document.querySelectorAll("[data-breed]");
selectAnimal.addEventListener("change", () => {
    options.forEach(option => option.hidden = option.dataset.breed != selectAnimal.value);
    if(selectBreed != ""){
        selectBreed.value = "";
    }
});

Apparently, you realized that if an item is hidden, it cannot be selected and therefore does not also need to be disabled.

The fact that you're thinking of effective alternative strategies is evidence of your learning progress and grasp of the material. Good job!   :+1:
