ELI5: Would Giving a Dog EnChroma Glasses allow it to see more colours?

No. Although a dog's vision is something like a human with red-green colour blindness, it's for a different reason than the type of colour blindness that EnChroma tries to fix.

A human eye has three types of colour-sensitive cells, which are most sensitive to red, green and blue. The most common red-green colour blindness happens when your red and green cells are too similar, so although your eye responds differently to red and green light the difference is very subtle. The glasses filter out some of the light which both the red and the green cells respond to, making a bigger difference between red things and green things.

A dog's eye doesn't have separate red and green-sensitive cells, it just has two types, so there's nothing the glasses can do. There's no subtle difference for the glasses to exaggerate.
