One of the hardest parts of potty training is getting your dog to let you know when he needs to go out. Imagine how nice it would be if your dog could come to you and tell you in plain English that he wants to go outside and take care of business. Of course, he can't exactly walk up to you and say, "Hey dude! I gotta go outside." But at the same time, there is no reason why he can't be trained to let you know in another way that he needs to pee.
The good news is that there are several different ways you can use to train your pup to "ask" you to take him outside. We all know how hard it can be sometimes to tell that our four-legged friends are trying to let us know he needs to go out before he ends up making a mess. This could be because some dogs are better at telling you of their needs than others.
Of course, it could be that your dog is already trying to tell you, but you simply aren't getting the clue. It is possible that you just don't understand his efforts. There are several signs he might already be using such as standing by the door, whining, growling, or wagging his tail. He might also start pacing, sniffing at things like furniture legs, or scratching at the door.
The goal is to teach him a specific method of letting you know that he needs to go out and take care of his business. Of course, if you see any of the above-listed signs, you should probably go ahead and take him out as quickly as possible. It could be that he is trying to train you to recognize the fact that he needs to go out.
Before you start trying to train your pup to let you know he needs to go outside, he needs to have been potty trained at least to the point at which you can take him out every couple of hours or so and he will use the bathroom instead of making a mess in the house. There are a few things you may need as part of your training program, including:
The only other things you need are plenty of time and patience. Your dog will appreciate you being patient as he learns this new skill and so will you when you no longer have so many messes to clean up.
