Wendy DeKalb, Illinois 3/6/2014 6:53:27 AM Hi Cesar,I am taking care of my daughter & son-in-law's lab (Duke), almost 1 year old and is huge. I also have a 5 year old shih tzu and 4 year old schnauzer. Duke is very smart, affectionate, etc. but won't listen. He uses the schnauzer as a chew toy and tries with the shih tzu until he runs and hides. He's so big when the grand kids come over he knocks them over and occasionally does the playful nips (he's getting better about that). He didn't get much socialization, with other dogs when he was smaller, so now that I have him, I'm trying to teach him how to get along with my two dogs. My husband has no patience with him so I don't know what happens during the day when I'm at work. Please help!
