yep. I self-select out of dog friendly offices. if that's a "benefit", I can't work there.

If they're allergic to dogs, yes. Like wat

Yes, they can indeed be a problem for people with allergies. In my case dogs (and cats unfortunately) trigger respiratory issues. I had that issue at a workplace where dogs were allowed, not fun times. And unfortunately medication like antihistamines are not an option for everybody, personally I get extremely drowsy from them, even from the latest generation meds.
