Result

Result after 48 dogs.
Note that this is an ongoing project, and the result will change some.

In average the pulse went down -5,72 % when we walked in a curve toward the dog
And in average the pulse rises +9,95%  when a person walked straight towards the dog.

Here is the result of dogs that is in a known area, and therefor there are fewer things that effect the result.

We believe that these dogs give the most correct result, and look at this! Here is a 27 % difference!
