I am so tired of people not realizing trust is a two-way street with their animals, but dogs in paticullar. I see all the time dog owners tighten their grip on the leash, pull away basically sending their dogs every signal that a threat is approaching. This is not cool. I understand that every situation is different and must be evaluated. I have a pack of 4. Three are very large, (btw I'm a cripple on atleast one crutch all the time) yet I can walk all the big ones and throw another large one that is untrained in the mix and still maintain control because trusting my pack is key. When another dog approaches your doggie baby or pack, how ever you define it, the approaching dog will act accordinly if your dogs trust you. I have disarmed more doggie owner even at petstores by telling them to relax. Your dog is a social animal, lower your guard and the animal won't feel the need to lunge but instead greet, maybe play, move on. BTW dog training that is successful is really a human liguistic in understanding dog language and speaking it fluently.
