Response to Mary

Mary asked, "If people were to stop keeping pets, what would the effect of society be as well as the animal world?"
Something that I do not think that we have touched on yet, are the health benefits of owning animals. People who own dogs and cats are less likely to have: heart problems, depression, high cholesterol, high blood pressure, high triglyceride, stress, among many other benifits.
So naturally, if people stopped owning pets the rates of these disorders would rise
For the animal world, the effects to fish, snakes and cats would not change at all. Yet, for dogs, it would change immensely. Like we have been discussing in class, and like Mary discussed in her post, dogs have been domesticated so much that they would not be able to survive on their own. We change them to have shorter legs, longer torsos, rounder snouts. We desire these traits because they are more aesthetically pleasing to us, or these traits are quite possibly desired because they are more human (a manipulated selection that is a borderline satire of The Island of Dr. Moreau). Our extreme breeding choices for these animals has given dog owners the opportunity to turn something that is suppose to be a nurturing act into a real life Cosmo quiz: What dog are you.
Dogs need us for their survival, and if all the dogs were dispersed in the woods, I'm sure some of them would survive. (probably not shitus or chuwuwas). Never the less, both the human world and dog would would have significant changes, because they are so intertwined.

Question: Because animals give us so many health benifits does that give us a reason to breed dogs so that there is at a right dog for everyone's lifestlye? That is to say, different dogs are specifically designed for a certain lifestyle.
