Those companies are not even remotely representative of American workplaces. Especially Ben & Jerry's; WTF??

Also, I'd sincerely like to know how they deal with employees who are allergic to dogs. Not to mention dogs shitting in the office, barking, getting in fights with other dogs, etc. Pit bulls in particular are infamous for attacking and killing other (smaller) dogs, and of course some "pit bull advocate" is going to insist on bringing her pit bull to work to prove to everyone how "sweet" he his, and then act shocked when it kills her coworker's Chihuahua, and worse she'll blame the Chihuahua owner somehow. Honestly, letting people bring dogs to work is one of the stupidest company policies I've ever heard of.

You're not going to get much of an argument from me about dogs; I honestly don't know why people like them so much. But as I said before, I'm one of those "cat people", so of course I'm not going to understand why people want to have a big, smelly, slobbering animal around that can't even figure out how to take a shit in a relatively clean and hygienic manner. Cats are far more sensible pets: they're smart enough to always crap in a litter box where it's easily managed, they're small (even the rare huge breeds aren't over 20 pounds or so), they don't smell (because of their fanatical cleaning habits and the chemistry of their saliva), and the only downside is the dander is an allergen to some people. You can even get automatic litter boxes these days which make the bathroom part really, really easy.

But I do think you're overblowing things a lot. As I said, I've never seen a workplace myself that allowed dogs (I never worked at Google, just like most of the nation; their ridiculous interview process keeps most qualified people out anyway), and I very rarely see a restaurant that allows them at all, in or out, or where people have them. In fact, I can't even remember the last time I saw someone with a dog at a restaurant, except for one time about 6 months ago inside a Panera where a guy had his service animal (which is something entirely different; very few people get those; I'm pretty sure this guy was visually impaired IIRC). The main places I see these dog-lovers out in public with their dogs is on hiking trails, at parks, etc.

Don't forget that Facebook is not a good way to judge peoples' lives. FB is infamous for having people post all kinds of crap on there trying to show how wonderful their lives are and one-up their friends, and it's driven a lot of people into depression because they see all these happy, smiling pictures. Real life isn't like that; what you see on FB is a tiny non-random snapshot or worse an act, or the shameless self-promotion of a vocal minority. Of course, all the dog proponents who can't spend 30 seconds without thinking about their dog are going to post a bunch of crap about dogs and their dog and how wonderful dogs are and "look! here we are going somewhere with our dog!" and "this restaurant sucks!! they wouldn't let us bring our dog in!!", and you see this and now you're thinking the whole country is like that. My advice: figure out who all these idiot dog-loving people on your FB feed are, and de-friend them, for the sake of your own sanity. Do you really want to see all kinds of dog-related posts on there every time you log in?
