This brick built Lego dog is the creation of uran120. This good boy (レゴ 犬) was originally made all the way back in 2018 for Lunar New Year. The build also comes with a red and black display stand, and some lucky bamboo. The dog has been built with movement and articulation in mind. It features joints in the legs, paws, tail, neck, ears, and mouth. If you can think of a good pose, chances are that this Lego dog can do it. He knows all the tricks: sit, stand, hand stand, lay down, and wave. The tail is an especially interesting build, using a bunch of white mechanical arm pieces and t-bars to create. This gives it a full range of motion. This little Lego dog should get all the pets.
