Cosmos is an approximately 50 lb teenaged Doberman/American Bulldog mix (according to a DNA test). Cosmos is playful and energetic and needs a lot of exercise to be happy! Cosmos is fully house trained and does well with new people in a neutral setting. He walks well on leash and has been doing great with crate training. Cosmos, true to his breed mix, is fiercely loyal and can be protective of his space and his people. He can be overwhelmed if there is a lot of activity and may do best in a quiet neighborhood. Because he can be rough and rambunctious in his play, and because he can be protective of his space, Cosmos would do best in a home with adults or kids 12+ only.
