Bereavement leave for pets

Should you get bereavement leave when your pet dies? It's a question that came up in the UK when a guest on a talk show said he'd be bereft if his dog died and he'd definitely need time off to grieve. In New Zealand you're only entitled to 3 days off if a child, parent, or partner dies. Counsellor Nigel Pizzini says society doesn't recognise some forms of grief.
