One of the things commonly done by pet lovers and owners is to hug or comfort the dog or puppy when it is scared. As Cesar Millan would say, giving affection to a scared/ aggressive/ fearful dog is nurturing that state of mind. In short, if the puppy is doing something you do not like him to do, it's always best to ignore him so he will understand that his behavior is not good.
Unlike humans, dogs and pack animals are unable to rationalize that our giving of affection to them is a sign of comfort. We've all heard of trainers and dog experts talking about the reward system. Getting frustrated towards a dog will make him think you're excited rather than angry. This also means that immediate correction is more effective than punishing a dog a little while later.
Some books have mentioned that if you are giving a dog affection at the wrong time such as in a fearful or aggressive state, this will give the dog reason to believe that he should be scared or protective of something.
As the mommy or daddy of the pack, it is important that your pooches can feel secure with you- and I'm not just implying financial security. Like us humans who need to feel safe under our government's reign, dogs need to know that their pack leaders can control their surroundings
- My pack leader is here so these dogs sniffing me won't do anything to me.
- The mailman will not steal the mail.
- I don't need to be bark at the visitors because my pack leader has control over the territory.
And with such protection comes discipline and rules they have to follow such as:
- No biting or nipping because the pack leader gets mad at me.
- The pack leader will always lead the walk.
- The pack leader does not want me to do this or he will snap at me again.
As for my personal experience, I believe one of the reason why Peanuts doesn't beg for food anymore is because she is being completely ignored whenever she does it. Her potty training went pretty fast as well, since every time I catch her doing her business on the paper, I instantly croon "Good Girl" and she approaches me for a good stroke on the back.
