While training a dog you can make a number of mistakes. First and most important mistakes new dog trainers make is that they think that a dog, like a human, can effectively respond to their words. They sometimes think that they can scare their dog into doing something. For example, you might state something like stop sniffing every mailbox you come to. Does that ever work? Well to a dog, since they obviously do not understand English he/she thinks you’re saying “Stop pulling my leash, I’m just marking my territory. Are you yelling at me, you try basically living in the laundry room. And those healthy science diet food. My word it’s like trying to eat a sock. The walk is my only haven. Hey I need to mark my territory. Once I run away, key work once, I need to go somewhere. So before you yell at your dog remember, he no hablo Ingles.” (I do not speak English.(In Spanish).)
