I think the solution is to get a dog.
Why do I say that? Well, then you'll find out how hard it is to train a dog, and once it is trained, how hard it is to get it to remember that training and act consistently. Dogs are intelligent, living, breathing creatures just like us, and they have minds of their own, just like us. Some of them have stronger wills than others, just like us.
You'll learn that towns and cities are very unfriendly places towards dogs and dog owners. You'll learn what it's like to sit outside cafes in the rain because you can't take dogs inside. You'll learn that lowland countryside is little better, with many landowners actively antagonistic towards dogs and their owners. You'll find the hills to be the last refuge where dogs can be dogs and humans can be free.
You'll learn how a dog thinks, and how it communicates with other dogs, and with humans. You may even learn how to communicate with dogs. You'll learn that dogs are loyal, loving and lovable. You'll learn to love dogs.
I say that as someone who was attacked by a large dog as a child. I still have a three inch long scar on my arm to prove it, forty years later. I have subsequently been bitten several times by dogs whilst a postal worker.
Oh, and you'll learn that taking a dump at the side of the path is a very inconsiderate thing to do.
Yours sincerely,
