Django - How to specify which field a validation fails on?

I have this model I'm showing in the admin page:

class Dog(models.Model):
    bark_volume = models.DecimalField(...
    unladen_speed = models.DecimalField(...

    def clean(self):
        if self.bark_volume < 5:
            raise ValidationError("must be louder!")

As you can see I put a validation on the model. But what I want to happen is for the admin page to show the error next to the bark_volume field instead of a general error like it is now. Is there a way to specify which field the validation is failing on?

Much thanks in advance.

abbreviated, from the django docs:

def clean(self):
    data = self.cleaned_data
    subject = data.get("subject")

    if subject and "help" not in subject:
        msg = "Must put 'help' in subject."
        self.add_error('subject', msg)

    return data
