Cheap room in return for dog sitting

I’m looking for someone maybe a student or someone working shorter hours who can help with pet duties. I work away in London and use a dog walker but would like someone to be around for the dogs a bit more from late afternoons and early evenings 3 nights a week. Can be flexible. Room is a double room with private bathroom all furniture provided in lovely 4 bed house. Dogs are very cute and friendly cocker spaniels
