There's a family with good sized property raising and boarding horses that has two wolf hybrids. I do a long run by their property probably once a month and had seen them in a huge outside kennel a time or two. The kennel is a good 25 yards away from the road I run on. I noticed them due to sheer size and was surprised and really, really happy to note they never reacted by barking or acting aggressive when I would run by them like most dogs in a kennel or yard.
One day I was running through a small park near their house that empties out to the road their house is on. The park path curves before emptying out to the road so you can't see all of the path. I run high and listen to music and when I'm in the zone of a runner's high I am oblivious and slow to react. I came out of that curve and was surprised by a little girl walking one of the hybrids not more than 10 feet away on the path in front of me. She froze and I could see the shocked and surprised look on her face, the hybrid's snarl and mentally forced myself to keep the pace steady and act calm as I gave them the widest birth possible. No exaggeration, the dogs head, on all fours was shoulder height on me. I know you should never run from a dog but I also know dogs can hear your heartbeat, smell fear, etc. so decided that abruptly halting the run in front of them would be worse than continuing on at the same pace. It all turned out fine but there was no way that little girl was going to be able to stop that dog if he/she really wanted a piece of me. The whole thing couldn't have taken more than a second but felt like slow motion and I'm proud to say that the only liquid in my pants was due to sweat
