Me and DH are looking for ways to earn extra money so are advertising ourselves to look after cats etc in people's homes when they go away on holiday. Not so much dogs because they really need to be with people all the time and we are thinking pop in in the morning and again in the evening to play/feed/close curtains etc. We already do this for our neighbour who goes away 6 or 7 times a year but we dont ask for money for it. Anyway what do you think we should charge? Per visit? Per animal? Per day? Dont know. We dont really have to take petrol into account as we will only do our village so it will all be within walking distance.
