Bearded Collie
The average longevity (the age at which half of the dogs has died and half is still alive) of Bearded Collies from recent UK and USA/Canada surveys (the average of all surveys is 12.8 years); Beardies in the UK surveys lived longer (average ~13.4 years) than the USA/Canada bearded collies. (median 12.0 years). Most breeds have average longevities between 10 and 13 years and most breeds similar in size to Bearded Collies have average longevities between 11 and 13 years, so the lifespan of Bearded Collies appears to be on the higher compared with other breeds (at least in the UK). Individual dogs may die much earlier or later than the average. In a 1996 USA/Canada survey, 32% of Beardies died (including accidental deaths) before the age of nine; however, 12% lived longer than 14 years. The oldest of the 278 deceased dogs in the 2004 UK Kennel Club survey died at 19.5 years; the age at death of the oldest dog in the USA/Canada survey was not reported.
