Here is my dog Blue, he is a 2 year old Neapolitan Mastiff:
Guard dog at my shop at home:
sleepin on the Job
These dogs take about 3 years to fully grow, he is about 140-150lbs now, fully grown he should be close to if not greater then 200lbs. We feed him about 4lbs of food a day, and he is growing fast.
