A group of American graduate students has developed a dog feeder which they think can make pets smarter.
The digital dog feeder uses behavioural science to set dogs gradually harder challenges with food as a reward.

My dog is very smart. He is a black Labrador. He can sit, shake, lay, roll over, jump and speak the syllables of his name.

I think my dog is very smart and clever because of his amazing sniffing skills. The best trick I have taught him is how to put on a seatbelt!

My dog's name is Lassie and she is cool. She loves children and she will tackle you if you are having a kick about.
My dog is not that clever but I think she's above average, she knows three tricks.

My dog, Bella, is really clever because I taught her to roll over when she needs a tummy rub. She's so cute when she does that.
