Seek comfort from you
If you have a good relationship with the dog and the dog is very dependent on you, then when the dog feels dangerous or uneasy, the dog will subconsciously look back at you. This is actually a dog seeking comfort from you.
Care about you.
Some dogs are strange. Sometimes they regard you as a master and a leader, but sometimes they regard you as their own child and need to guard you all the time. So every time you pass the dog, the dog will look back at you to see if you are in a good mood or a bad mood.
Want to take you to its secret base
Dogs have a strong sense of territory. If dogs trust them very much, they will want to take you to its secret base. There may be dogs' favorite toys, hunted prey and even their other half.
Stay alert
In fact, when you pass by the dog, the dog will look back at you, or it may be because you are on guard. Because dogs have excellent sense of sighing and hearing, they are very sensitive to danger. In the face of unknown danger, the dog will subconsciously turn around to confirm whether the danger is big or small.
Smell the food.
If you have delicious food in your hand, the dog will definitely look back at you when you pass by. Because dogs are very greedy and persistent about food, they will ask you to give them some only when they see that you have food in your hand.
