Is a dog a dependant?

It seems to have been a week for rather bizarre questions, so I thought I would share the favourite – is a dog is a dependant for the purposes of a contractual emergency leave policy?  Granted the drafting in question isn’t perhaps as tight as it could be but still – requesting compassionate leave to “support your puppy” because one of the other dogs in the litter (bought by a friend) has died is stretching things just a tad, even accepting that the policy “does not say anything about dependants having to be human”!
