When your dog first sleeps on the bed with you or begs at the dinner table it may look quite cute, especially if your dog is still a puppy. At first, allowing the dog or puppy on the bed, or on a chair at the dinner table seems like the right thing to do. It makes the dog happy and the owner happy. They are initially happy because they can enjoy each other's company by cuddling in bed or partaking in dinner together. As time goes by both the owner's expectations and the dog's perception usually begin to insidiously change.
Dogs have a very high sense perception.
I believe they are able to sense emotions in their owners beyond the capacity of most humans. It is the perception of the dog that then indicates that the dog is being called upon to fulfill an emotional need of the owner. Dogs, having the desire to please their owner, will attempt to fulfill this emotional need in human terms, yet they can not, they are dogs. Let me explain the significance of this perception. In doggie world, a dog that is physically higher than another dog indicates they are dominant over the other dog.
