This past weekend we got two six month old Schnauzers. They were said to be house broken. They have doing well with the peeing, but they are both having a pooping problem. They get taken out every 2 hours during the day, right before bed, and first thing in the morning. I took both of them outside this morning, and 10 minutes after they were back in the house they both duked on the carpet. Anyone have a solution on how to correct this behavior? Aren't they so cute?
