Why does my dog pee in the house?

Oh Behave!
Q & A With Pet Expert Arden Moore

Q. My 10-year-old Bichon Frise sometimes goes to the bathroom in the house when no one is home. As soon as I walk in the front door, I know what Rascal has done without seeing the accident. She acts incredibly guilty, with downcast eyes and tail between her legs. If she feels so bad when she misbehaves, why does she continue to do it? Also, I think she sometimes urinates on the floor to get even with me for being gone for too long. The longer I am away from home, the more likely she is to have an accident. Is she trying to get revenge?

A. Many owners consider their pets to be members of the family, as well they should. But sometimes, we take this idea too far by attaching human emotions and motives to our dog’s behavior. Unlike humans, dogs don’t feel guilty when they have done something we think is wrong. They do, however, react to our body language and tone of voice, and they quickly learn to read and respond to our emotions.

In Rascal’s case, she has figured out that if she has an accident in the house, you will be angry when you get home. It’s very simple in her mind because unlike a human, she can’t grasp complicated ideas like, “I had an accident and five hours later, Mom is going to come home, see it, and get mad at me because now she has to clean it up.” All Rascal knows is that if she has had an accident, you are angry when you come home. Dogs have no concept of cause and effect, so unfortunately, she doesn’t realize that if she didn’t go to the bathroom in the house, you would not be mad.

So, if Rascal doesn’t know she did something wrong, why does she look so guilty? Dogs often behave submissively when their owners are angry, in the hopes of ending the conflict. In wolf packs, subordinate members behave submissively in front of the more dominant wolves to avoid fights. Rascal tucks her tail and hangs her head when she senses or anticipates your anger to illustrate her submissiveness to you, her pack leader. Signs of submissive behavior include a cringing posture, lowered ears, downcast eyes, and a tucked tail. A canine pack leader would most likely accept this behavioral apology and move one. Unhappily, people tend to become even angrier when confronted by such signs of “guilt,” which makes the poor dog cringe even more.

As for the possibility of Rascal going to the bathroom in the house to get even with you for leaving her alone too long, dogs do not have the capacity to think in these terms. Revenge remains an exclusively human endeavor, and something only a complex brain can calculate. Dogs don’t have the mental ability or the emotional complexity to grasp the concept of getting even.

Rascal’s accidents are most likely the result of her inability to hold her urine for long periods of time. She may be suffering from a urinary tract infection or another medical condition that makes it hard for her to hold a full bladder for an extended period of time. Older dogs often have trouble with incontinence and sometimes need medication to remedy the problem. Take Rascal to your veterinarian for a complete physical evaluation. In the meantime, try not to leave her along for too long to help her avoid accidents. This might mean asking a neighbor or professional pet sitter to come over and let her out to relieve herself on days you know you’ll be gone for a long period of time.

    Our Pug poops in the house not just in the house but on our bed and on our pillows when he dose not get to go with us, So now he gets crated when ever we go anywhere. Myself I think they do it to get even for leaving them behind. And yes dogs know when they have done wrong. When our pug pooped on the bed he put his head down would not look at us. So yea I think they know what they have done and that it was wrong.

    My ten year old toy poodle has found that if he hides under the bed in the morning, he won’t have to go into his crate while I am at work. I cannot afford a pet sitter to come let him out during the day. He doesn’t pee in his crate but if left alone in the house for five minutes he will pee. He has ruined the carpets in my house. He poops and eats it to hide it. I am totally disgusted with my dog right now. This issue has escalated since I returned to work after being unemployed for almost two years. I have tried taking him for a walk every morning, which is his favorite thing in the world, but still he pee’s on the carpet.

    I feel for you. I had the same problem with my 6 year old lab. I would highly recommend the course at . It’s online and it works.. My dog is cured!

  4. Dara Bradley says:

    I disagree with this article as well. My dog has a doggie door and uses it all the time but when we leave for a while she goes on the rug at the front door. I have thrown away many rugs, cleaned the floor and she still does it on the next rug. While all the time having access to go out. I know she just gets angry for being left alone.

      Hi Dara, I totally agree with you. Thank You for your comment.
      I know my dog knows better and still potties in the house, even if we have just let her out. and she understands the commands ‘potty’ and ‘poop’, so I know she knows better, in 11 years I have never caught her in the act.

      I guess I’m not going to get my expert answer on the internet..
