How to catch a runaway dog
Follow the dog.
If you are with the dog when it runs away, discretely follow it and keep it in view without chasing it or being too obvious. At some point, the dog will stop to check out a smell or dodge a person and that is a potential time to move in closer.
Select from the following.
[a]. Try not to make it evident that you are tracking the dog or it will see your pursuit as a game of chase and run even faster. Entice the dog with tasty treats..
[b]. If this happens (though you might not be interested in this version of the game), follow that faint trail until you get behind it. At this point, don't worry about pursuing after the dog alone..
[c]. This is because the dog is already cornered and will very likely ignore this then rush to the rescue. Hold the approaching dog by its collar or leash..
[d]. In effect, you are following and monitoring the dog to see what it is doing and running away. Even if it is not paying attention to you, it will tend to ignore you and you will only have to continue tracking it..
