How do you approach a dog?

Have you ever walked straight towards a dog?

Have you ever thought about how the dogs react to this?
This is the first impression you give a dog when you approach him/her.
Do you want to show that you are friendly, and want no harm?

After having measured many dogs in this situation, the results show that the dog’s pulse goes down when you walk in a curve towards the dog, and the pulse usually rises when you walk straight towards the dog!
