"A recent study shows that your dog is probably as smart as your average toddler.
Researchers at the University of Florida have found that dogs have the intelligence of a 2-year-old. They are capable of understanding the meaning of up to 165 words and gestures, can count to 5, and can perform simple mathematical calculations.
Another study found that dogs can interpret human body language and behavior and use it to their advantage.
Researchers said dogs are more likely to beg for food from someone who is paying attention to them.
Using tests originally designed to demonstrate the development of language, pre-language and basic arithmetic in human children, the researchers were able to show that the average dog is far more intelligent than they are given credit for.
That study is published in the journal Learning and Behavior."
This makes me think that our Husky is pretty bright and interactive, but our Shiba is very apathetic and interacts only when he chooses... so I think they both understand us and can sense things, but i'm not sure if either can count to 5... What about your furbabies? You think they can measure up to a two year old?
