House trained dog pooping inside
We have a house trained dog, which started doing his business inside the house three days ago.
Previously this has happened maybe 3-4 times since we have this dog, and we have never punished him for it since he did not do this on purpose.
This behavior now is different though. Instead of alerting us if he needs to go, he simply goes to another room (always the same one), poops there, and then comes back. Or he waits until we leave the house and then does it, even if we are only gone for 10 minutes.
We do take our dogs for 20-30min walks 3 times a day, and so I do not understand this behavior. I have read, that changes in diet/surrounding might cause this, but neither is true in our case.
Has anyone had a similar case, or knows how to solve this issue?
Thank you
Michael
