If you have ever had an animal that went missing,even for a few minutes, you have experienced the many emotions that take over.
Finding lost animals is wrought with fear, anxiety, panic and lack of control.
If the animal has escaped to go out on a jaunt it could include joy on their side not on yours. There are as many variables, emotions, and situations as there are animals.
We as the human know the inherent dangers of what could happen. They on the other hand, such as in the case of a Beagle, may be just following a scent. Something they were bred to do, unaware of the dangers that might surround them.
