The American Kennel Club recognizes two separate varieties of beagle: the 13-inch for hounds less than 13 inches (33 cm), and the 15-inch for those between 13 and 15 inches (33 and 38 cm). The Canadian Kennel Club recognizes a single type, with a height not exceeding 15 inches (38 cm). The Kennel Club (UK) and FCI affiliated clubs recognize a single type, with a height of between 13 and 16 inches (33 and 41 cm)
English and American varieties are sometimes mentioned. However, there is no official recognition from any Kennel Club for this distinction. Beagles fitting the American Kennel Club standard – which disallows animals over 15 inches (38 cm) – are smaller on average than those fitting the Kennel Club standard which allows heights up to 16 inches (41 cm).
Pocket Beagles are sometimes advertised for sale but while the UK Kennel Club originally specified a standard for the Pocket Beagle in 1901, the variety is now not recognized by any Kennel Club.
A strain known as Patch Hounds was developed by Willet Randall and his family from 1896 specifically for their rabbit hunting ability. They trace their bloodline back to Field Champion Patch, but do not necessarily have a patchwork marking
A Puggle, a beagle/pug cross, shows traits from both breeds.
In the 1850s, Stonehenge recommended a cross between a Beagle and a Scottish Terrier as a retriever. He found the crossbreed to be a good worker, silent and obedient, but it had the drawback that it was small and could barely carry a hare.
More recently the trend has been for “designer dogs” and one of the most popular has been the Beagle/Pug cross known as a Puggle. Some puppies of this cross are less excitable than a Beagle and with a lower exercise requirement, similar to the Pug parent; but many are highly excitable and require vigorous exercise.
