Last year a big cat came into our backyard and our male dog went for it. The cat did the hissy/yowly cat thing but the dog called its bluff. Turns out housecats don’t bring very much to a dogfight. He picked the cat up mid body and thrashed it. I got there just before our second dog showed up and saved the cat. The dog had a deep puncture in his cheek. I didn’t get to check out the damage to the cat, but it was mobile at least.
