Our small coop recently approved the first dog in many years, but only after drawing up an agreement that specified what issues would trigger a request to the shareholder to find a new home for the dog. Our rules say dogs only by special permission, and I have heard that in the past there were dogs that did create noise and mess that bothered other tenants significantly. With most of us now working from home--and the kids here doing school at home--it's even more important that a dog not bark all day long and disrupt everyone. But we did approve the dog, which has recently arrived, and so far I've not heard a peep out of her. And she's really cute. I hope it works out, but on the other hand, I do think that in a small coop it might be a problem if everyone had a dog. Especially if they were larger dogs, who might not only bark but also make considerable noise running around the apartment.
