Genetic link to dog friendliness

[Catherine]

Cats fascinate us and we love them and their strange ways, but dogs are our friends. You relax with a dog. You can get silly with a dog. You just know you can count on their loyalty.

Dogs are the only species that is so intensely friendly with us.
It makes sense that there is a genetic aspect to this.

We may have bred dogs for centuries and have selected for friendliness and cooperation, but I think dogs were friendly when they first got involved with us. I think that is why they got involved with us. The real question now should be "Why us?".
What do dogs see in us. We don't always treat them right, but they still love us and protect us.

A cat wouldn't stick around if we didn't treat them right.
Dogs are unique in their loyalty.
