Why is my 8-month-old male Shih Tzu suddenly peeing on everything?

Updated on September 23rd, 2025

Pet's info: Dog | Shih Tzu | Male | unneutered | 5 lbs

My Male Shih Tzu is 8 months old and he is starting to pee everywhere. When he was smaller he refused to pee on concrete and rocks, grass and inside only. Now that he is fully potty trained he only pees in the grass, but for a couple of weeks hes been peeing on our trash can inside the house and out side on the grill, the kids basketball stand, and a beach chair. He will pee there first or pee in the grass first then 45 seconds later he goes to the concrete to pee on those three things. HELP

You have one probable and another possible problem. Trappy has discovered his male self and has begun to mark his territory. Additionally, there may be a bitch in heat somewhere in the general vicinity of your house (a dog can detect the scent of a bitch in season from quite a distance away). He is at the ideal age to be neutered, so I would suggest that first of all. Then, you need to re-housetrain him. Put him on a leash and take him outside to his designated spot. Do not walk around. Just stand there and repeat "go outside" or a similar phrase. As soon as he starts to go, repeat "go outside" and praise "good dog!" as he goes. When he is finished, or if you think he has stopped before his bladder is empty, or he does not go after a reasonable amount of time, bring him directly back inside. Do not remove the leash. Attach it to your belt loop and keep him with you. Don’t let him out of your sight! When you see him start to circle or sniff, take him right outdoors again and repeat the process. If he does mess in the house, do not scold him unless you actually catch him in the act. In that case, say "NO!" and take him right outside. Tell him to "go outside" and praise as he finishes. Keep him in a crate at night, or for short periods when you are not at home. For further assistance with this, click on the prompt to initiate a consult. Good luck!

My puppy was potty trained, now having accidents. What went wrong?

I see that Murphy is still very young, only about 3-4 months old - this is much too young to expect him to be reliably housetrained. Most small-breed puppies like Shih Tzus are not reliable until at least 6-8 months of age or even older, so it's very normal and expected that he is still having accidents. You will need to be patient with him while he learns. Take Murphy outside frequently (every 20-30 minutes while he's awake and active) - go out with him so that you can watch, and reward with a treat as soon as he pees or poops. Inside, he needs to be supervised at all times to prevent accidents. If you aren't able to watch him, or when you're not home, he should be confined to a crate or a puppy-proofed room where accidents will be easy to clean up. If you see him start to have an accident, just hurry him outside to finish up there - then praise and reward as usual. It's actually not recommended to use any type of punishment for accidents in the house, as it usually doesn't help and just makes your puppy afraid of you. If he has an accident, clean it up without comment and focus on supervising him better next time.

Why is my 9-month-old neutered Maltese marking in the house?

He probably started marking when his hormones increased. Now that he’s neutered these levels will go down over the next four to six weeks. Please clean all of the area he’s marked with lemon or vinegar cleaner to remove the scent. I recommend going back to crate training for housebreaking, or using a male belly band when you aren’t able to monitor him. Please take him outside or to the pee pad frequently so he has a chance to urinate there. Marking behavior can become a habit so working to stop this right away is best.

Why is my unneutered male dog suddenly peeing everywhere inside?

Inappropriate urination occurs when a dog regresses to urinating inside the house. This behavior is more common in male dogs that have not been neutered, although it can occur in non-neutered dogs and cats. The first thing to rule out is inappropriate urination that occurs when there is an underlying health problem which is causing a dog to urinate inside the house. It may have lost control of the muscles in its bladder or sphincter, or there may be an infection (UTI) or other condition as drinking too much (seen in many medical conditions) that is making it difficult for the dog to hold it in long enough to get outside. When a medical caused has been ruled out we can think about the second type of inappropriate urination which is behavioral (such as marking). I recommend to take Bakar to the vet with a "fresh" urine sample to first check or rule out medical causes. Hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach.

Why is my Havanese male suddenly peeing and marking inside the house?

I would recommend seeing your veterinarian first to rule out a urinary tract infection or other lower urinary disease like bladder stones. Even though you’re not seeing blood these wouodnbe common causes of sudden inappropriate urination and its important to rule out a medical condition first. If Pog’s urine and other testing is normal you can discuss restarting house training with your vet.

Why does my dog pee inside after going out? Is it a tantrum?

Please do not ever, ever rub your dog's nose in his pee or poop. He has no idea what you're doing and why. Also, he does not "throw a temper tantrum." Kids do that; dogs don't. Put him on a leash and take him outside to his designated spot. Do not walk around. Just stand there and repeat "go outside" or a similar phrase. As soon as he starts to go, repeat "go outside" and praise "good dog!" as he goes. When he is finished, or if it appears that he is not going to go, bring him inside but do not remove the leash, even if he has done his business. Attach it to your belt loop and keep him with you. Don’t let him out of your sight! When you see him start to circle or sniff, take him right outdoors again and repeat the process. If he does mess in the house, do not scold him unless you actually catch him in the act. In that case, say "NO!" and take him right outside. Tell him to "go outside" and praise as he finishes. If he does do his business in the house and no one is right there to correct him, he will have no reason to believe that he is doing something wrong. Keep him in a crate at night, or for short periods when you are not at home. If you continiue to have problems with this, you can click on the prompt to start a consult.

How to potty train an unneutered dog that marks territory inside?

If he is not neutered this can be a behavioral issue. I would recommend neutering him immediately to hopefully stop this behavior. I would also recommend crate training him. You must choose a crate that Hachi can stand up, sit down and turn around. A crate should only create a positive environment. Never use the crate for punishment. Despite what many people think do not line the crate with blankets or beds. Keeping Hachi in the crate when you cannot keep 100% eye on him is important. Every time you take him out of the crate take him on a walk to make sure they go to the bathroom and give positive reinforcement if he does. If they do not eliminate while you are outside then put Hachi back in the crate for another 20minutes. After 20 minutes take him out once again to try. If Hachi does go to the bathroom make sure you take time to play with him and when you have to turn your back again put them back in the crate. I hope this helps.

Why is my intact male dog suddenly marking in the house at 16 months?

I see that Zeus is not neutered - unless he is a show or breeding dogs, this is the first thing I would suggest doing. It's extremely common for intact male dogs to have issues with urine marking in the house once they reach social maturity, usually around 12-18 months of age - so it sounds like Zeus is right on time for this behavior. I would also recommend supervising him constantly when he is in the house so that you can interrupt him if you see him starting to lift his leg, and confining him to a crate or dog-proofed room when you aren't home to help prevent accidents. A belly band (essentially a diaper for male dogs) can also be helpful in the short term while you are working on the problem.
