Correcting Dogs Potty Behavior

Hello WumpyPPancakes and welcome to myLot! I'm glad that you're determined to solve the problem and you excluded giving them up from the start. Now, you didn't say anything about the age of the dogs but I assume they are both adults. Dogs don't do anything "out of spite". We, humans, have the bad habit of humanising our dogs' actions. They do their duties inside either because they don't have the opportunity to do it outside, or because they weren't properly housebroken. I suppose you take them outside to do their business at least three times a day: fist thing in the morning, last thing before going to bed and sometime in the middle of the day. If not, you can't ask them to keep the house clean... If you do take them outside often enough, it means they weren't completely housebroken while they were puppies. In this case, I suggest you to start housebreaking them from scratch. Crate training would help making them understand you want them to eliminate only outside. Keep them locked inside a crate for 2-3 hours at most, then take them outside to eliminate. Congratulate them enthusiastically once they did their duties outside. Don't allow them to walk free around the house until they're completely housebroken. Of course, cleaning the old bad smelling spots in the house is a must.

I think you should start teaching them potty behavior as they were puppies. Probably they were not properly housebroken when they were young and they haven't learn that going potty inside is a No-no!. They both need to be correctly housebroken, or else, once one of them pee inside, the other one will pee, too, to mark up their territory. Did you teach them to to their duties inside? I remember it took my friend almost three months until her dog was completely housebroken.

I am having the same problem with a dog here in my house. It is not really mine, my friend adapted it and left it here when he left the house, now I am it's caretaker. I don't know much about disciplining or training dogs as I am more of a cat person so I would just lock the dog out of the house at night. He stays in the porch until the morning comes and then I allow him inside again, that way he does his peeing and manuring outside at night.

I am afraid it is not out of spite, but because their scent is still there and they will continue to return to that spot until the scent is gone. I have used diluted bleach, but there are products on the market that will help get rid of the scent. You probably can not smell it, but they can.
