Well, this study shows I'm not so far off the mark:
The canine IQ test results are in: Even the average dog has the mental abilities of a 2-year-old child.
The finding is based on a language development test, revealing average dogs can learn 165 words (similar to a 2-year-old child), including signals and gestures, and dogs in the top 20 percent in intelligence can learn 250 words.
Border collies, poodles and German Shepherds are among the smartest, according to the tests. Dogs are as smart as 3 and 4 year olds when it comes to math, the story says. And they surpass even teens when it comes to social skills (but are we really surprised by that?).
Granted, I don't see rat terrier on that list, but I'm pretty sure my dog is still as smart as most toddlers.
For one thing, she's totally potty trained.
