A overprotective loyal beast ( description )

Rocky is my overprotective loyal friend an unusual beast that lives underground and curios of other. Fur softer than anything else, ears just like an bunny, it's even bigger than a 15 year old and has sharp teeth. It may look cute but when you try to hurt me it will climb up from underground and will come up to protect me by barking just like a dog but louder. When Rocky shows his teeth you would walk back slowly and then will run as fast as you can back to your house, but he is nice if you know him and if you are a family to him he will sleep on you and even lick you that is a kiss to him.
