Yelling Doesn't Create Enjoyment
Ever wonder why owners struggle getting their dog to listen around distraction and why simply raising your voice doesn’t work?
Yelling is the wrong type of motivation for that kind of scenario - especially if the dog is more motivated by the excitement of the distraction than listening to you.
Emphasizing what you say or yelling commands may get your dog's attention a little better, sometimes, but it won't lead to a consistent, reliable response from your dog.
If we end up yelling commands but get no response, we usually just end up feeling frustrated. Over the long-term, it gets old, and may even lead to resentment.
In fact, if you really want to make things difficult long-term, and create a dog who is less likely to want to listen to you, yelling is one way to do it. But that's not why you got your dog. I'm sure you wanted to have enjoyment and a happy companion instead.
Since dogs have the ability to simply ignore their human (trained or not trained), if you want your dog to listen, you will need to follow through with what you say as a command and that is usually some kind of guidance the dog can "feel" such as leash pressure or ecollar.
Whether it's leash or ecollar, the varying degrees of sensation the dog feels and responds to is referred to as "pressure" in the dog world.
Understanding training tools, their use, and pressure as a motivator, off leash reliability becomes more of a possibility...same with a happy life free of stress.
