Best Dog Training Methods

He has long been house trained. He is not under any particular stress or changes. He is not sick and he already goes outside multiple times a day. Even if he wants to go out in between he used to signal that he needed to got outside. The even odder thing is that he only pees and poops in strategic places like right in the doorway when you walk in the house or bathroom so you will step in it. Has anyone had this problem before and do you know what causes it?

It could be a health related issue, such as a urinary tract infection, bladder infection, worms, etc. So many possible things. I would highly suggest you take your dog in to see a vet.

Also, if the dog is getting old, it could be age related.
