Think about it, people do the same thing when they are in a "nippy" mood. Ask your self: "Why do I make growling noises and snap at people when I am not in a good mood?" You just don't want to be bothered, right? Same thing with dogs. Dogs are a lot like humans, just so you know.

Horses are not capable of growling. They do not have the voice box structure to make that sound. If you notice that a horse seems to be making a growling noise all the time, it is likely stomach or bowel sounds. The horse is likely hungry.

Cats make a spitting noise when playing to mimic the sound of a hissing or growling animal, which is a natural behavior to show excitement or aggression during play.

Mine doesn't but if your does you may want to check your car's brake pads to see if they are worn down. That growling noise could be the metal pads making contact with the rotors. If that's not the problem, check your fuel tank. There may be a tiger in there.
Dogs produce noises on a frequency higher than human hearing. When happy, they make ultra high growling noises that are undetectable to humans. Cats, on the other hand, have a different physiology. Their noises are audable to us and vibrate (the purring noise) due to the unique shape of their voice boxes.
