According to a 2017 Swedish study in the Journal of Scientific Reports,
keeping a dog may enhance happiness and lifespans, but not the other way around.
In addition to frequent vet visits, healthy diets, and daily exercise, certain dog traits promote longevity.
Large dogs have shorter lifespans, therefore individuals desiring a long-term bond may prefer small or medium-sized breeds.
More particular, certain breeds outlast others.
The Tibetan spaniel was originally developed to guard Tibetan monasteries.
The flat, silky coat and "lion's mane" around the neck give this dog a close, worshipful attachment with people.
