A reader sent me this pic. Trust me: these dogs are trained. Which reminds me - we need a series on dog training, hunting and regular obedience. It's an important topic, and only the rich farm it out to experts. I have trained my own. For regular obedience, they have been quite good but for hunting they have been a little "difficult." They like the birds too much and behave like children when there is too much game around. My fault.
If you feed a dog, he'll love you. Any dog will snuggle. The training is the deeper connection in which you learn to think like him, and hopefully mostly vice-versa. His work is to anticipate your wishes just as our work is to anticipate our bosses' wishes (but at Maggie's, we try to avoid having bosses other than God).
Any dog can be trained to the whistle and to hand signals. Any human can learn God's hand signals.
