Meet Tetris! Tetris is a young male cattle dog mix whose goofy energy is perfectly balanced by his affectionate soul. Bouncy and fun-loving, Tetris is happiest when he is spending time with humans, his whole body wiggling as he comes over to greet his new best friends. Picked up as a stray in Arizona, the history we have on Tetris is minimal. However, his sweet face, expressive ears, and mild temperament all speak for themselves.
