Four dogs and 11 puppies have been stolen from farmland in Doncaster.
They were taken from Stainforth Road, Barnby Dun, between 8.20am and 7.30pm on Saturday, May 7.
The dogs include a red Malinois, which is distinctive because she has one-and-a-half ears, a brindle male Dutch Shepherd, a white female American Bulldog with a brown mark over one eye and a fawn and black female German Shepherd.
The German Shepherd has a distinctive 'V’ cut out of her right ear.
The puppies are two-week-old Malinois and will be red and fawn in colour as they age.
Anyone with information should call South Yorkshire Police on 101.
