Quotes from Richard A. Wolters

Picking the breed is important. I have a friend who got a schnauzer for his wife. I told him I thought it was a good trade.

Once the command is learned, stop giving him the praise. The dog must learn to do the command for the sake of the work. Watch a good worker bring in the duck, you will see that the doing is the reward. Save the praise for in front of the fireplace, when the work is over.
