Americans are very big about loving the dog first, so when you tell them you have to set rules and limitations, a lot of people believe it's going to hurt their feelings. They're actually looking for you to be the pack leader.
Cesar MillanA dominant dog can get another dog to move out of its way just by the energy it projects. You can tell a lot about a dog's position in the pack by how they hold themselves around other dogs. When reading a dog's body language, you can't do it intellectually. You can only do it by using your instincts.
