if the dogs are using the house as a toilet, they aren’t housetrained. there’s only so much you can do to fix this…you can work on training and you can clean the carpets/walls with an enzymatic cleaner, but EVERYONE in the house needs to be on board.
this situation sucks, and i’m sorry you’re dealing with it. 🙁
PLEASE familiarize yourself with the symptoms of Puppy Strangles. Currently going through treatment for it with my puppy. See a vet IMMEDIATELY.
