We have a dog friendly office and it drives me crazy sometimes. One dog is fine but when you get them in pairs they like to play. And having a dog wrestling 4 feet away from you is distracting.
I like dogs and I will make it a point to befriend the ones in the office but at some point it becomes disruptive.
Yes, that's kind of the key. A single dog at the office is great.
A bunch of dogs turns the office into a dog park.
I love dogs, have two of em, wife is a key member of a dog rescue, and I loved bringing my dogs in the office. But no way do I want a bunch of dogs at the office.
One dog decided that he was in charge of figuring out if people were "allowed" to be in the office and that he should bark if they weren't. I wasn't on the list the first couple days and would literally get barked at if I walked across the office to get water.
I personally just hate/fear dogs after too many bad experiences growing up. Everybody looks at you as the burden or party pooper when you say you would prefer a dog free environment to work at.
Not me personally, but some people are allergic. I'm allergic enough to cats that if my employer forced me to work around them, I would just leave. Some people are that allergic to dogs.
I've worked at UK army bases where dogs are routinely brought on site. In some places the owners have to fit gates to their office doors to stop them randomly wandering around, and I've not seen dogs in open plan environments. In some places, in principle, the owners have to gain consent from others (those with allergies or nervousness). But I've not seen specific problems.
At least the cavalry types no longer ride their horses to work.
