"There's no secret to dog training, but there certainly is a key: consistency.
I often refer to dogs as "pattern matching machines." I'm being facetious – of course, I think of dogs as more than machines – but dogs are very good at recognizing and storing patterns. It makes sense too: predators and scavengers that can quickly recognize where prey or food might or might not be are rewarded by nature.
You've undoubtedly seen your dog pick up on these patterns. The sound of someone approaching your door. The sound of their favorite family member's car. The sound of the refrigerator door opening. Each of these is a chance to store and later recall an association. That is how learning works.
So, when there is no obvious pattern, it is very difficult to learn. When your dog cannot learn, he'll improvise. You probably don't want that.
A consistent environment that is full of consistent signals is what you need to present to your dog. A predictable environment results in predictable behavior. " Eric Goebelbecker
Most of the problems I encounter with my dogs fade away with time, training, and consistency. Now my husband makes for a bit of a problem. He usually is quite good at making "consistency" go out the window. And, you know how hard husbands are to train! They do fairly well with click/treat, but when you try to fade that...they go back to their same old bad habits.
With 5 dogs, going out the door becomes a mad dash because 2 of the 5 dogs are young BCs. I have been extremely consistent with the dogs. I can open ANY door and walk outside while all 5 dogs will wait in the house until they hear their name called. Now, how to get them to walk calmly out the door instead of looking like they have been shot out of a cannon! That's my next dilemma as a trainer.
P.S. I have to add something here. I have it remedied going out the front door, just not the back door. When I call them name by name out the front door either to their kennels or to the truck, they walk out and lie down on the porch and wait for the next set of instructions. But, the back door to the dog yard is a whole different ballgame. They don't do it there because they go in and out all day and I am NOT consistent. And, my husband is NOT consistent. They are patterned to speed. :0)
