Try a potty patch. If you can get him to use it move it slowly towards the door everyday. Also a doggie door might encourage him to go out there if it is a convenient option that is always available.
you mean are all dogs potty trained? Then no.
If a service dog is trained correctly, then it will be potty trained.
You should really "potty train" your dog when you first get them, you shouldn't really have left it that long. BTW: You don't call it potty training you call it house training or house train.
This is a difficult question and can be frustrating. See the related link for information..
I may not be perfect, but a good dog training system is one of positive reinforcement. This means whenever a dog does what you want it to, you give the dog treat and praise. When a dog does something bad, you simply say no in a stern voice.
Use Puppy Pads :)
Depends on you. Not the dog..
potty train it
To train your male dog to use an indoor potty, you can start by choosing a designated spot for the potty and consistently taking him there at regular intervals. Use positive reinforcement, such as treats and praise, when he goes potty in the right spot. Clean up accidents promptly and avoid punishing your dog for mistakes. With patience and consistency, your dog can learn to use the indoor potty.
Get dog mats, take your dog outside frequently, and reward your dog every time it uses the dog mat.
Like I say in most of my answers, it all depends on the dog. However, in general, puggle puppies are pretty easy to potty train. So if you have a dog of this breed, potty training should be pretty easy for you.
no you have to train them
