Why you should never take your dog to a dog park?

Dog parks were build to promote, among other things, the idea that dogs can have a social area “to play with other dogs”, which by definition does not match with the essence of the species. What do I mean by that? Dogs are predators and pack animals. They’re genetically designed to fit in a pack and build their lives around that group. They operate in survival and defensive mode and dealing with strange dogs in the same fenced in area is completely against their nature. That is why we see, and hear about, many dog fights inside dog parks. But why the fights happen? What are the triggers and how do we trace them back to specific causes?
