He is 2, a lab mix. He is outside all day while we are gone and in with us at night. I was going with the collar for when we are not around. I work with him when we are home, so like you said it isn't bad, he is learning. Now he needs to learn when we are not around.
I am very worried for when they start building next door, he will bark at the men all day! I don't want that to happen.
Thanks for the advice!!
