Dogs understand their homely environment, they are aware of their owners who feed them and provide a safe heaven for them, thus they willingly perform household tasks for them. When humans do all these works for them, they take them for their sole masters, dogs easily get impressed. Many dog behaviors are not acceptable in a human society, for instance biting, to stop such kind of acts by a dog, it is important for humans to remain in charge of their dogs and don’t get pushed over by them.
There are some common behavior that we humans avoid in dogs but such behavior can create a problem after a while, behavior like Stubbornness, Headstrong and willful Demanding, Pushiness, Begging. Pushing a toy into you or pawing in order to get you to play with them. Nudging to be pet. Sitting in high places looking down on everything. Guarding a human from others approaching. People like to call it ‘protecting’ but it’s actually ‘claiming’. Dog owns you. Barking or whining at humans which many owners consider “talking” (without a command to do so). High pitched screams in protest of something dog does not wish to do. Jumping or putting their paws on humans (without a command to do so). Persistence about being on a particular piece of furniture when you ask them to stay off (dog owns it). Persistence about going in and out doorways before humans. Persistence about walking in front of humans while on a lead. Persistence about getting through the doorway first. These are some behaviors which should be watched by the owner and you should take corrective action if found in your dog.
Here is a question, how to know that your dog is going to do some massive things so the answer is just by looking towards your dog and the way he carries himself can tell what frame of mind the dog is in, lets take an example, how will a dominant dog walk, he will walk with high and pride he carries his body stiffly and tail is up and rigid where as the ear are on alert.
