Must have been some wimpy German Shepherd. Any large dog should be able to put down any domestic cat, even a Maine cooncat in short order. I had one crazy neighbor who kept two full grown Bobcats out of the South Carolina swamps as pets and he did not take a chance on letting them get into fights with dogs. As he put it, a cat’s bones are much finer and easier to break than a dog’s bones, any cat that has been crunched in the jaws of a sizable dog is not likely to live long. I have had my own hand and forearm raked and bitten by a black shorthaired tomcat that weighed at least 15 pounds and had only minor scratches, nothing to frighten me.
Nope, not at all. This dog was the "neighborhood tough," and as such, he chased the cat up a tree. After a few minutes, when the dog was satisfied with itself and turned to wander off, the cat jumped out of the tree, onto the back of the dog and did some damage. When the dog couldn't get it off it's back, the dog first tried scraping the cat off, using the tree, then rolling over, and at that point that cat latched onto the dog's belly and started raking the dog's belly with it's hind claws. Like I said, it took over 60 stitches to close the dog's wounds.
