My dog is behaving like a new puppy

[brooksj68]

I have a Maltese who will be 3 in April.  He potty trained quickly.  We take him out about 10:30-11 and he can hold his pee until the morning.  The last 2-3 months he has been peeing & pooping in the house even though there are puppy pads out for him which he trained on.  Last night I found out he peed on the sofa cushion & this morning he went poop in his potty place then came to the door and peed on the mat outside the door.  I'm very confused by his actions, anyone have any advice?

Glad you took him and the infection is being treated.  Just keep reinforcing his training, accidents or not.  Hopefully, when this clears up he will go back to his normal routines.

Thank you for the advice.  I did take him to the vet yesterday and found out he has an infection so we are starting on meds and hopefully that will stop the peeing in the house.  If not I'm going to start back at square 1.  Thanks again!

First off, is he neutered?  Any new animals or people in the house? Have you moved?  Anything going on outside near your home?  Anyone go back to work recently?
First off, you may want to get a Vet exam o make sure there is no infection going on.
You may just have to go back to  square one with the training and not let him have the un of the house when you are not there.  Is he crate trained?  If so, crate him at night and limit food and water after his evening meal.
