CMV: The existence of anxious breeds of dogs is just cruel on the face of it.

We have been preferentially breeding dog traits we like for thousands of years. One thing essentially all dog breeds have in common, because we’ve created the trait through hundreds of generations of purposeful choices, is the emotional need to be near us. It’s so pronounced in some breeds (and individuals) that, in my view, it really borders on cruelty. To create and own an animal that is constantly depressed when we’re not around, then leave it alone for eight to ten hours a day, (WFH notwithstanding) simply because we enjoy the emotional rush of its happiness and relief when we return and temporarily relieve its misery, is unforgivably selfish and borderline sadistic. 

I don’t know what remedy exists for this beyond ceasing to breed the most anxious and nervous little dogs. In the far future, I can see a more enlightened culture condemning us for being so blind to what we were doing to this wonderful species.

Edit: A number of people are focused on the “remedy” I mentioned, which I think is a bit of an afterthought. I would amend it to acknowledge that another acceptable solution might be convincing humanity on the whole that we need to be aware of the essential cruelty of imprisoning a very social animal in isolation for long periods of time. Many individual dogs, and presumably some breeds on the whole, are far more emotionally needy than others, and this should be understood. 

The view I’m asking you to change isn’t how we fix this, but the fact that it is a serious problem that most dog owners fail to acknowledge or take into account when they choose to get a dog, and that the fact that anxious dogs are anxious is our responsibility. When they were wolves, they lived in packs and their social needs were met. We seized on their pack mentality, redirected it toward ourselves, and preferentially bred individuals who were more attached to us. (That’s domestication) The most extreme forms of this are tantamount to cruelty.

This is not an issue of the existence of the breed per your own account:

> To create and own an animal that is constantly depressed when we’re not around, then leave it alone for eight to ten hours a day

It's an issue of mismatches of dog to person.

There are people who are suited for dogs that are basically attention sponges, but the issue is that people tend to pick dogs based on appearance or misinformation or status instead of appropriate temperament, energy level, drives, etc.

This extends beyond just anxious dogs.

That people can and do mistreat dogs does not demonstrate that dogs shouldn't exist, since the obvious alternative is that people should treat them better - and some people demonstrate this is possible.
