Duke is a very sweet pit mix. He is great with other dogs and likes cats. He is ok with kids if he is introduced to them well. He is great with adults. He needs more space to run. He is very loved by his mommy and daddy but we know our home is not enough for him. He has grown up with a Chihuahua and a cat. We recently got a pit mix puppy and he is very nurturing with her. We want to do what's best for him and want him to be happy. Not having enough room has caused him to become aggressive and we can no longer keep him.
