thank you for the info, very interesting to read. It still amazes me that some dogs do so good one way, and others different. But then that could also be the time and effort the owners put into it also for a high success. I am just baffled by the amount of dogs I see that don't even respond to their name, let alone a command.
is it clicker training that they use for the dogs in agility?
My personal take on cat purring:
1 cat Mono
2 cats Stereo
3+ cats......Surround sound
