Why does my dog like ice so much?

My dog is about 1 year and 6–7 months old. He is a labrador retriever mixed with a pit bull. Whenever I go and get ice, he comes up to me and sits by me wanting a piece of ice. At first, I thought it was because of him teething (we got him when he was a puppy) but now he’s older and I don’t think he’s teething anymore.
I don’t think anything is wrong with him liking ice, I am just curious as to why.
I’ve never had a dog like ice so much.
