1.5yr old Purebred English Mastif Male Very Large/ Trained in Las Vegas, Nevada For Sale

I don't have the luxury of keeping him anymore due to downsizing to an apartment. He is extremely calm, trained, mellow, big boned, amazing dog that is sociable with other dogs and young kids. He is most likely the biggest dog you will see in Las Vegas and will turn anyones head in public especially after he fills out around 2yrs old. He is breed that needs someone who can financially afford him as this breed requires higher upkeep but the bonding reward of this dog is 10 times that as they are amazing family dogs. I am asking $600 rehoming fee as a fraction on what was spent on him.
