Tucker is house trained. We keep him outside while we are gone, but when we are home he is in the house with us. He stands to my waist, I am 5'7" tall. He is small for a boxer as he was the runt of the litter. His original owner had him as a house dog as well, Same schedule as i have him on now. He lived with two other small dogs before I had him and they got along very well.
