To a newbie, Nigerian Dwarfs and Pygmy goats can look very similar. They can, many times, be the same height and weight, but pygmy goats tend to be stockier and have shorter legs. Pygmy goat’s genetics are designed for meat production, so they tend to have a much thicker build in general. Nigerian Dwarf goats have a more slender neck, and thinner, longer legs.
Pygmy’s tend to have a limited amount of colors and markings and only have brown eyes. Nigerians have lots of different color combinations and can have bright blue eyes.
