#10 Mastiffs tend to be lazy and need daily exercise to keep from gaining too much weight.
#11 The Mastiff is considered a breed with a short lifespan, but some Mastiffs have lived to 18 years of age.
#12 When Mastiffs reach adulthood and overcome their clumsiness and energy, they are wonderful companions who are calm, quiet, well mannered, and self-assured.
