If you're a Shih Tzu owner, you may sometimes wonder exactly what your dog is thinking. Science has actually uncovered gestures and signs your dog makes that mean they love you:

1. Direct stare into the eyes

Experts translate this as the equivalent of a hug, and there is even scientific proof to support it. Looking into the eyes of your pet is not only a way to express love, but also releases the hormone oxytocin which makes you feel happier and more bonded with your pooch.

2. Lifting and wiggling of their eyebrows

For a long time, people have associated tail wagging as a form of communication for dogs, but facial expressions can be even more powerful. Movement of the left eyebrow or ear is an indication that a dog approves of the person they are in contact with, or the action that is being performed.

3. Yawning when you yawn

Yawning is contagious, and if your dog yawns when you do, it could mean that your dog is connected to you emotionally.

4. Cuddling after a meal

Dogs love food, and studies suggest that the action that follows eating is a sign of what they value most. A dog that cuddles with you after they are done with their meal feels comfortable with you and wants to spend time with you.

5. Leaning on you

When you lean on another person, it means that you are secure and assured of their support. Dogs lean on people they love because of the affection and security they feel with them.

6. Calmly watching you leave

Contrary to what people believe, a dog that panics when they sense you are leaving is insecure and does not trust you. Your dog will only be calm as you leave if they are confident that you will be back because you love them as much as they love you.

7. Jumping at your return

We know people love us by the way they react to us. A dog is not able to hide joy when its loving owner returns. Look out for tail wagging, jumping up and down, licking your face and bringing you a toy - all indicators of love.

8. Sleeping in your room

Dogs choose where they get to sleep, and a dog that loves you will want to sleep in your room and as close to you as possible.

9. Brings you a toy

While this gesture might mean that your dog wants to play with you, it is an indication that he or she does not mind sharing precious and coveted things with you because you are important to them.

10. Showing love

All the above signs are all illustrations of how dogs express their love. Dogs can sense your love for them and then reciprocate with one or even several of these gestures.

11. Following you

A dog that loves you will want to be with you everywhere you go. Dogs follow people they love because of the affection they feel for them.

12. Instant alertness when they see you

A dog can be sound asleep but when someone they love enters a room, all that sleepiness vanishes. That is love!

If you give your love to your dog, you can rest assured that you'll receive some of these gestures and indicators of love in return.
