Why Would A Dog Start Peeing In The House?

The most common reason your formerly housebroken dog may start peeing in the house is due to a medical condition such as diabetes, kidney disease, or bladder issues. You should also consider if there has been a change in the dog's routine, such as being left alone at different times of day or for longer periods of time. It's also possible that your dog may need a housetraining refresher course.

It's Frustrating, But Don't Punish Your Dog For Peeing In The House 

You know what's worse than having to clean up dog urine in your house? Smelling urine and being unable to find it. That's what you may be faced with if you punish your dog urinating in the house, because next time he'll try to hide it.

Instead, you need to determine the cause or, in some cases, start again with potty training.

Medical Conditions

If your housebroken dog starts peeing in the house, there is a good chance it's due to a medical condition. That's why any sudden changes to your dog's bathroom habits should be reported to the vet as soon as possible. The good news is that once the problem has been addressed, the dog will usually return to his proper bathroom habits.

An exception to that would be if the problem has caused long-term incontinence. In that case, you'll need to consider installing a doggy door or having your pet wear diapers while in the house. 

Changes In Routine

If your dog is left alone more than usual or at different times (i.e. you changed shifts or started working overtime), it can be difficult for his body to adjust to the new routine. One possible solution is hiring a dog walker or having a neighbor come over to let him out. 


As is the case with humans, some dogs start to lose control of their bladder as they get older. If this is determined to be the problem, more frequent trips outside is often the simplest solution. If that isn't enough, consider restricting the pet's access indoors to rooms that you can easily clean up, or some dogs do not mind wearing a dog belly bands or diapers.  

When a dog suddenly starts peeing in the house, don't ignore it. Even if you suspect it's due to aging, it's best to visit your vet just to be on the safe side.
