We asked at our local vets, and luck would have it one of the vet nurses also house sits, she walked ours briefly in the mornings, went to work, left the radio one, came back at her lunch time, had her lunch and a play with them, then when she returned after she had finished work, she took them for a long walk and then spent the evening with them, before retiring to bed complete with 2 dogs and 1 cat!
I was really sad when she moved on, but through a friend I have found a 22 yr old girl who still lives at home, (her family have dogs-so she is used to them) and she enjoys coming here to a house all on her own.
Its great for us knowing the dogs, cats, fish and house are looked after and the dogs love her, its her 4th year housesitting for us.
Whatever you decide to do have a good holiday!
