I find it's generally unwise to let on to someone that you have low expectation of their abilities. Jessica and I have gently and (somewhat) jokingly suggested to one another that maybe Tulip doesn't learn as quickly as other puppies and that perhaps she's goofy and loveable but maybe not that quick.
Our dear darling has now gone out of her way to prove her intelligence to us. That magical bark collar? Yes....well.....Tulip has figured out that while a BARK will set it off, a WHINE will not.
(You must reeeeeeead that in a high pitched puppy voiiiiiiiiiiice.)
All night long.
