Just Like Yoga
Dogs don’t just stretch when they wake up. They do this for the sake of their muscles. It might symbolize love and affection as well. When you get home to see your dog stretching, don’t think they just woke up. This is a way for them to show you they’re happy to see you!
Exposing Their Belly
When a dog shows you his belly, it means they respect you and feel submissive. Maybe they also want to play with you. The only way to respond here is to rub their belly! They’ll want it to happen over and over, so they will keep doing it. However, they might also display this kind of behavior when getting attacked by another animal.
