Although beagle-type dogs have existed for over 2,000 years, the modern breed was developed in Great Britain around the 1830s from several breeds, such as the Talbot Hound, the North Nation Beagle, the Southern Hound, and possibly the Harrier.
Beagles might also be affected by a range of eye issues; two common ophthalmic conditions in Beagles are glaucoma and corneal dystrophy. "Cherry eye", a prolapse from the gland from the third eyelid, and distichiasis, a situation in which eyelashes develop in to the eye causing irritation, sometimes exist; each these circumstances may be corrected with surgery.
The Norfolk Spaniel or Shropshire Spaniel is a breed of dog extinct since the early 20th century. It was originally thought to have originated from the work of one of the Dukes of Norfolk, but this theory was disproven after being in doubt during the later part of the 19th century.
