Mate of mine needs to rent, or ideally house-sit, a place with his two dogs from November for 6 months - preferably a little house with an enclosed garden, in Surrey or Sussex. Where (ie. which websites, publications, etc) do you suggest he looks?
Just look on Rightmove. If he sees anything he fancies he'll need to check the ad to see if animals allowed. If he is going to go out to work and leave them all day then I doubt anyone will rent to him in the private sector.
