if dogs are allowed then why not other pets?
lets have a think about this:
dogs: no matter how much you love a dog and how well trained and behaved they are, they can still go mental and bite someone.
cats: i’m allergic, go away.
snakes: health and safety would mean you’d have to tape them down to make them less of a trip hazard.
parrot: likely to repeat the nasty things you say about your boss, office supply of crackers greatly reduced.
angry gay muslim swan: too sensitive to handle the office banter.
rabbit: likely to start a fight with the swan.
see, no chance of this working out.
