Just Like Yoga
Many people stretch after they wake up. Dogs, on the other hand, stretch for their muscles. It can also symbolize affection and love. If you find your dog stretching when you get home, it doesn’t mean they have just woken up. They are stretching because they feel happy to see you, which is simply the cutest thing!
Exposing Their Belly
A dog showing you its belly respects you. They feel submissive and probably want to play with you. Rubbing their belly is your best response! They like this, so they will show you their belly a lot. However, they also show this behavior when some other animal attacks them.
