The Old English Sheepdog has been put on a watchlist of endangered dogs as fears rise that it could face extinction.
Just 316 puppies of the breed, known affectionately as "the Dulux dog", have been registered this year, the Kennel Club has warned.
The Queen's favourite breed - the Pembroke Welsh Corgi - the Soft Coated Wheaten Terrier and the Welsh Terrier are also on the list for breeds with only 301 and 450 puppies registered.
The Kennel Club hopes to highlight the plight of Old English Sheepdogs before they slip to the vulnerable level of less than 300 puppies.
Currently there are 30 vulnerable breeds as well as the four dog types on the "At Watch" list, the club added.
The most vulnerable breeds are the foxhound, which had no registrations so far this year, and the Cesky Terrier, which had just 25.
