physiologists have long noted the correlation between brain size and intelligence in animals. Chimps, apes, humans..as one example...Dolphins, and whales...as another...the bigger the brain, the more intelligence is displayed.
Then there's dogs...all breeds do the same basic things...yet a Great Dane has a brain 20x the size of, say a Yorkie...so why isn't there a far greater capacity for intelligent behavior in the larger breeds. What do they do with all those extra brain cells?
Pugs are to hug, of course. A good acquaintance of mine rescues Pugs and told a story that if she has a dog fight, she throws a blanket over them and lays down on it. I’ve been trying to imagine that for years now, but I can not imagine a pissy Pug, no matter how I try.
