Paw Pats
It is not nice to get slapped by a person, but this is not equivalent to a dog slapping you with a paw. They are not angry, only trying to catch your attention. It is even more different when a dog slaps another dog. For them, it is a sign of trust. Think of it as the same thing when we pat one another on the back.
Eating And Cuddling
If your dog cuddles you right after eating, they are showing you how much they adore you. A lot of dogs want a nap after a good meal. There is no better place for them to do this than beside their favorite human being! It is a very good idea to cuddle up with them when you have a dog who does such a thing.
