Blue loves to dunk during hot days on the farm

for Blue the answer is Both. But preference to disc.

I'm curious to see what the breakdown is, and if it's neither, what is it?

This is Blue's first time eating ice cream for dogs, while I wouldn't give your heeler these frequently, once in awhile is fine and I think he really enjoyed it on a very warm spring NJ day. It does feel illegal to feed a dog ice cream but happy to report no tummy issues
