“Every day, the humane societies execute thousands of dogs who tried all their lives to do their very best by their owners. These dogs are killed not because they are bad but because they are inconvenient. So as we need God more than he needs us, dogs need us more than we need them, and they know it.”

“Every dog might wish to be Dog One, but like us, most dogs want membership in the group even more than they want supremacy over others.”

“I always thought of deer as solitary animals that weren't very interesting. But my goodness, that was very wrong. The big eye-opener for me was that they're social. They have family groups.”

“We fill the woods with invasive primates camouflaged to look like piles of leaves who sneak around, sprinkling estrus doe urine and manipulating gadgets that sound like antlers clashing.”
