They are brutally strong. My dog as a puppy chased everything that was small in my backyard. He brought me squirrels, birds and one night a possum. I have had to put some things out of their misery. Which sucks, but he's a dog. So he brought me a possum and rather that see it suffer I knocked it in the head with a bat. Hard. I went out the next morning to clean it up and wrap it in a trash bag so it wouldn't smell all week until trash day.
The thing was gone. No trace. I don't know how it survived. But ever since then I respected those things on a whole new level.
I don't think so. Unless it was another possum. My backyard isn't gigantic. But it's small enough to hear anything else. And I live in the suburbs. It's not like there are bears or anything.
It's not something I wanted to do. But I felt it was better than letting it suffer like other animals he has brought me in the past. Now he's 5 and doesn't catch as much. In fact last time he got caught on the fence and a squirrel bopped him.
