That was going to be my comment, only from the puppy person perspective (what I've been told by breeders).I have always told my puppy people to expect 10-12 years from a Golden. I believe a study has been done showing that to have been the same for a long time now. The larger the dog, the shorter the life expectancy. Toy dogs can be in excess of 15 years, while Great Danes and Irish Wolfhounds can be in the 6-8 age range.
This is the exact same life span that I've heard quoted. But, this is likely inclusive of accidents and severe illnesses.The last official results that I had seen listed male goldens with an average life span of 10.7 years and females a little higher at 11.4 years. I always tell families interested in one of our puppies that the average is 10-12 years.
