Mando is a 2 year old blue heeler/collie mix who we adopted this past summer. He is a very calm dog, especially for a blue heeler, and we have loved having him. However, as he has become increasingly protective of our kids he has also become aggressive toward their friends, barking and even biting other kids when they get rambunctious. We no longer think we can safely keep him, but we would love to see him go to a no-kid home where he would be a great companion. He is housebroken, fixed, and knows basic obedience commands.
