Due to his giant size and age, he is at risk of geriatric problems. With drinking more water and a decreased appetite, he needs to be checked by your vet to have blood work and possibly x rays done. They can start with checking for kidney disease or diabetes or an infection, then make sure there are no hidden masses or abnormalities in the bones or chest with the x rays.
