Atlas has one of the sweetest dispositions you'll ever find! He is fantastic around all animals, and isn't the least bit prey driven. He has lived with cats, horses, many other dogs, and currently lived with a few young children who he is amazing with. He has a love of life, and has a goofy personality that will bring joy to anyone! He is great on, or off leash, and love's his doggy play time. I have his mother, as she was also rescued, and her DNA for those who are curious. His siblings ears do stand up, so I think it's possible his will as well. Even if they don't, his ears are part of his endearment! He has medium energy, is house trained, quiet, respectful, and great for rides in the vehicle. I anticipate him staying around 50-55 lbs full grown.
