I had an animal show up in our backyard by my daughter's swingset today. It looked like it may have mange. It stood about 18 inches tall to the shoulder. Was a tan color. The tail seemed striped, but that could have been due to hair loss which was evident? It was very thin and looked desperate for food. I felt very sorry for it. He seemed as though he was suffering. Neither my husband nor I knew if it was a fox or a coyote. We also would like to know if he is sickly, would he pose a threat to my daughter who plays in that area? I have pictures, but could not download them to this post.
