Monty is a really small mini Dachshund and only weighs 4.5kgs - he's very loveable and prefers to sleep on your lap while you watch TV etc - he is mostly a house dog but will happily go for walks as well.
He doesn't have any special dietary requirements but we don't feed him table scraps or sweet stuff. At night he sleeps indoors on his dog cushion once it is placed on the floor at the end of our bed and will sleep all night - he is house trained but will need to be brought outside several times a day to do his business. He is not neutered.
