Your pup with the lighter nose looks JUST like my sister's dog. She got him from a breeder in New York State I think. He is also VERY hyper and had a habit of peeing on everything (including their bed) for awhile. When he is in one of his moods he will run all over the house ricocheting off of the furniture.
She was just firm and consistent with him. Took him a little longer to learn than some, but he got it - he's very smart, but stubborn!
