What could be wrong if your dogs haven't peed in the house in five years but now they have for the last two weeks?

== == Some dogs (especially small ones) are extremely sensitive to change. If a couple are getting their home renovated, painting, moving furniture around or even putting up the Christmas tree, having a lot of people over at one time it can make pets nervous (more so as they get older ... just like some people.) It's best to scold the dog by saying "shame" and putting them outside to do their business and bringing them right in again. Then it's extremely important that sometime during your day (make the time) have play time with your dogs and get back on a more even keel. Your dog could have a bladder or kidney problem. Take it to the Vet. Yes go to vet, is your dog getting older? have bad back legs or hips? The dog could be a diabetic also, especially if the dog is laying down and when the dog gets up there is a pee spot, from high blood sugar a diabetic dog will get rid of the excess sugar that way, i don't think they even realize they are leaking the urine, and at times when they do know it after they get up they will start to lick it up either they know they were bad or its the sugar in the urine. Both previous answers are fine but I would like to add that in case your dog is young and a visit to the vet proves it to be in perfect health, you should also know that sometimes a dog might pee inside for "revenge". If you did something that caused stress to your dog, even if you didn't realise, e.g. left him alone for a few hours (even if he\she is used to being alone for some hours everyday) but if something happened on that particular day at the time it was alone and got them scared that could cause them to pee inside to get back at you. So what I'm saying is that if you exclude any bladder and kidney problems they might do it on purpose. It can be hard to find out why since the cause maybe something that happend while you were not there or even something that happens often but this time caused your dog to be very sad or very scared for some reason. Answer Dogs can also have incontinence problems where their muscle in that area cannot contract as it used to and therfore leaks urine. Take your pet to see the vet and they can run a urinalysis to see if there is any bacteria, glucose, or crystals. They can also run bloodwork to test kidney values. In terms of the incontinence problem, it is treatable with medicine.
