So some sort of animal or something has been coming into my backyard for the past 2 nights and fighting with my dog or something
We have foxes, but my dog is a Rhodesian Ridgeback, (bred for hunting lions) and a fox would stand no chance. Kangaroos can't get in due to how high my fences are, and there are no other animals around big enough to fight my dog. So I'm quite worried about what it could be-
