Dogs Are as Smart as a Two-Year-Old

Your dog has about the same level of intelligence as a 2-year-old human child. It’s why they’re able to pick up 250 words, much like a human kid. They can also pick up on gestures that alert them of the mood their human is in, which is why they’re so responsive when you’re reprimanding them.
Dogs Can Get Jealous

According to a study at UCSD, if a dog catches you showing another animal some affection, they’re more than capable of becoming jealous. So, if you like petting other people’s dogs, make sure you do it when your pet’s not looking.
