There have been some dog breeds that were similar to the Beagle, one which is the Southern Hound and is thought to be an ancestor type dog to the Beagle. Another type of dog is the Talbot Hound also thought to be related to the Beagle as it resembled beagles much like the Southern Hound. During Medieval times the word "beagle" was only said to refer to small hound dogs, which were basically smaller versions of the modern Beagle.
On its formation, the Association of Masters of Harriers and Beagles took over the running of a regular show at Peterborough, England that had been started in 1889, and the Beagle Club in the UK held its first show in 1896. The regular showing of the breed led to the development of a uniform type, and the Beagle continued to prove a success up until the outbreak of World War I when all shows were suspended. After the war, the breed was again struggling for survival in the United Kingdom: the last of the Pocket Beagles was probably lost during this time, and registrations fell to an all-time low. A few breeders (notably Reynalton Kennels) managed to revive interest in the dog and by World War II the breed was once again doing well. Registrations dropped again after the end of the war but almost immediately recovered.
