Dog Lunging and on-leash aggression
Thereare some important basic leash manners which all dog owners and their pets must learn if they are to interact well with other leashed dogs and their owners. Many times an adult dog who has aggression problems learnt these unfortunate traits as a puppy due to poor or misguided training. An example of this is that adult dogs don't appreciate younger dogs jumping on them or getting too close. Now if the adult were off-leash he would simply move away (or signal) if he didn't the unsolicited contact. However when a dog is on-leashhe feels constricted and confined which can lead to feelings of anger and frustration, which can then be expressed through aggression.
