A keeper. Brian Hare absolutely knows what he’s talking about and cites well for when I’m looking for more details on some of the studies he mentions. I disagree with him on the efficacy of clicker training (if you expand your search from “clicker training” to “positive reinforcement with marker” it turns out it’s actually quite well studied) but that’s such a small portion of the book, and he’s very good at laying out how dogs are very smart in some areas and much less so in others.
