When I brought my dogs in from the back yard tonight the coyotes were really howling up a storm! I don't know if it was the brilliant full moon or if they had just made a kill. Occasionally, I see them through my back fence. There's an orchard behind me then a riverbed and they use the riverbed as a trail up to the mountains. They have actually come to the back fence to "play" with my dogs. One morning I saw one out there in one of those haunches up front end down play postures and I thought it looked so cute! Then another one came up, then another and another and I decided it was time to break up THAT "playdate!" But for the most part they have stayed away. Partially because I read that unneutered male urine will deter them, whether wolf, or human, so I asked my gardener to take his "potty" breaks through the back fence! My neighbor's son, who was working for him at the time, also did it so I guess it might have worked because I never see them that close anymore. It's a lot cheaper than buying wolf urine to spray back there!
