Ammonia is a base. Why can't Arrhenius theory be used with respect to ammonia?

arrhenius theory states that an acid is a substance that donates protons ( H+) in aqeous solutions.
arrhenius also states that a base is a substance that produces hydroxide ions ( OH-- )
arrhenius theory for ammonia is not valid because ammonia ( NH3 ) does not produce( oh-) ions.

NH3 is a gas. And as a pure compound it does not have an OH so by the Arrhenius definition it is not a base.
However, NH3 does disolve in water to make NH4-OH. Does that look like an Arrhenius base? We call that compound Ammonium hydroxide.
From the Lewis perspective, or the Bronstead-Lowery perspective NH3 is a strong base.
