My backyard is an urban wildlife refuge. We get racoons, squirrels, lots of birds, and have a resident cottontail rabbit population. My dog, Molly, is half Russian spaniel, half golden retriever, and loves the chase. She stands on the back porch, having a good look around when I let her out in the morning, then launches herself at whatever she sees. And she is very fast. A few years ago she was slow to come back in one evening, and when she showed up at the back door, there were two rabbit legs sticking out of her mouth. She has also caught and killed a squirrel. I've broken her of killing the wildlife, and she is content with just the chase, now. Yesterday morning, she was very exited about something she had found in the sandbox under the playhouse I had built for my grandchildren. When I had a close look, there were 5 baby rabbits that the momma rabbit had deposited in the boxed in structure. My dog, Molly, was very gentle with them, and hadn't hurt them. I figure that since they were just getting to that active, running age, momma had moved them to this confined area to keep them where she could find them. I haven't seen her, and suspect she visits at night when it's safe. I'll have to keep an eye on them to make sure they are getting fed.
