It seems like we know everything about dogs. They love to eat, walk for a long time, and have their belly scratched. However, these animals still can surprise us. Their owners sometimes even have to check whether they really got a dog or some other pet.

At Bright Side, we couldn’t pass by these 20+ photos of dogs, who seem to be having an identity crisis. In the bonus section, you’ll find a warning about what could happen to your cat if it sees this selection.

1. “Yes, I am definitely one of the cats.”

2. “Marty was raised by cats. Can you tell?”

3. “My girlfriend moved in and brought her cat. Since then, I’m pretty sure my dog has started to think she’s also a cat.”
