You might want to consider joining the CinnamonTrust, Jennyjoan. They aim to help out when, for example, people become too ill to take their dog for a walk or when a pet owner has to go into a residential home that doesn't allow pets. I can't claim to know much about their work but membership is only a fiver a year for those over 65, so there could possibly be some benefit from joining. (Even if you never use the service yourself, your money will be going to a good cause, I think).
I've just signed up myself:
