Hello, we have a puppy, I say puppy because he just turned one in July. He is a bigger dog though, unfortunately that why we have to get rid of him. Our home and yard is too small for this guy. He's awesome, does good on walks, knows what "no" means, "come here", "slow down", and "sit". We don't have any children but do have a niece and nephew, he has never been mean towards them or anyone that...
