A veteran dog-owner and trainer asks the question in more, er, colloquial fashion, and comes to terms with the fact that her puppy just isn't that smart. Money quote:
Over the past two months, she's made some progress, but it's been painfully slow and is easily forgotten. Still, I was living under the assumption that maybe my dog just had a hidden capacity for intelligence - that all I had to do was work hard enough and maybe she'd wake up one day and be smart and capable like a normal dog. Until last night.
