Dog housetraining problems were among the ones that cropped up on a recent survey I did. Here are some:
I have a rescue dog, only had her a month. Can’t get her to speak to go outside potty. Has had a few accidents in house.
My dog is afraid when he is outside, so I am training him to use training pads. If in the future he becomes more comfortable outside, can I still train him to go potty outside, or will it be difficult after teaching him to use the pads?
I am having a problem with excited peeing.
First, let me mention that I have a very long page on dog potty training on the website. It’s actually one of the most popular pages on the site!
It doesn’t directly address these three questions, so here we go:
 I’ve had several rescue dogs and we can only guess at their pasts. We don’t know what housetraining attempts were made or if the dog was punished in inappropriate ways. A friend of mine had a sweet little rescue dog who could go for long long walks without peeing once. As soon as they got back into the house, she would let loose. Ironically, this dog was named Sweet Pea! They worked it out over time.
So with a rescue dog, I suggest that as much as possible you treat her like a young puppy, always taking her out after meals, watching her like a hawk while you are home and confining her to a smallish area while you are away. You may want to read my long page on crate training and its benefits. You didn’t mention the age of your dog, but with adult dogs, there are different challenges than with puppies. Adults can go longer between pit stops but it can also be harder to extinguish existing habits.
 I think it should be easy enough to train him outside later. You could use training pads outside as a transition. Be sure to work with him to make him less afraid outside. You could try feeding him just outside the door…
 I don’t know much about this one firsthand, but I do know that it isn’t really a housetraining problem and that puppies are likely to outgrow it. It often occurs during greeting time, so if that’s the case, keep greetings low key. You might want to get the dog to sit at times when it might be inclined to pee excitedly or submissively, as doing something different could both distract it and make it less likely because of the position it would be in.
