when did the english white terrier become extinct
English White Terrier The name "English white terrier" was invented and embraced in the early 1860s by a handful of breeders anxious to create a new breed from a prick-eared version of the small white working terriers that were later developed into the Fox terrier, the Jack Russell terrier, the Sealyham terrier and later in America â€“ the Boston Terrier and the Rat terrier. In the end, however, the Kennel Club hierarchy decided the "English white terrier" was a distinction without a difference, while the dog's genetic problems made it unpopular with the public. Within 30 years of appearing on the Kennel Club scene, the English white terrier had slipped into extinction. It was, however, crossbred with the Old English Bulldog giving rise to the Boston terrier and Bull terrier.
American Cocker Spaniel American Cocker Spaniels in UK and USA/Canada surveys had a median lifespan of about 10 to 11 years,[30] which is on the low end of the typical range for purebred dogs, and one to two years less than other breeds of their size.[31] The larger English Cocker Spaniel typically lives about a year longer than the American Cocker Spaniel.[30] In a 2004 UK Kennel Club survey, the most common causes of death were cancer (23%), old age (20%), cardiac (8%), and immune-mediated (8%).[32] In a 2003 USA/Canada Health Survey with a smaller sample size, the leading causes of death were cancer, hepatic disease, and immune-mediated.[33]
