Urine is 95 percent water and five percent urea, uric acid, minerals, salts, enzymes, and various substances that would cause problems if allowed to accumulate in your body4. Normal urine is clear and has a straw yellow color, caused by a bile pigment called urobilin.
I would personally not use the wood pen. If it was the source of the odor, you’d probably know pretty quick by giving it a sniff. Even if it’s not, any scent that sinks into will encourage him to go there again. I recommend a commercial puppy pen (plastic or metal) or the use of a kennel/crate-at least until he’s learned he can’t potty everywhere. Much easier to clean as well. I don’t know how old he is, but if he’s quite young, he truly cannot physically control it past a certain point, so if you have to leave for long periods during the day I place a blanket or towel on one side of the pen and a potty pad on the other so they can differentiate where they potty from where they hang out. I know-people say if the area is small enough they won’t go potty where they sleep. This is not true. Plenty will, and then they traipse in it! So potty pads come in handy for keeping them out of the mess and tracking it around as well.
We also plan to purchase a carpet cleaning machine as soon as it is on-sale, and we will clean our carpet ourselves every three months. We trust that after a few cleans, we will get most of the stuff out. In the meantime, we vacuum our house very frequently. Every cleaning helps!
As for rented apartments.. mmm keep cleaning.. or ask your landlord if you can replace the carpet with something else. Its in their interests to say yes really because if it smells of pee when you move out, though they will take your deposit, they still have to get a replacement put in..
Many of the cheaper cleaners simply won’t work on set in stains and odors. If that’s the case for you, then you’ll need to make sure that you get it with something strong, soak it, and leave it for a considerable period of time.
Assuming the pee has not saturated the padding underneath, I have used Odormute, for over fifteen years with excellent results. Originally, I was told by a local police that they use this product to remove the blood from cement at crime scenes. It is natural enzyme product and totally safe as far as I can tell and I am a fanatic about natural products. You will still need to use a cleaner on the carpet; nonetheless, the odor should be gone.
Avoid ammonia. High in alkaline, ammonia should never be used to clean pet stains. It will leave a sticky residue in the carpet and damage the carpet fibers, attracting dirt and other debris. It will also attract pets back to the same area, because ammonia contains the same uric acids and salts that are present in urine, making it all too tempting for your pet to remark the area. Never use ammonia on pet stains. 
There are a few different types of carpet cleaning machines out there to be aware of. Some are definitely easier to use than others, allowing them to be used by those who are a bit less physically capable.
This spot cleaning unit fits away quite easily, and you’ll find that you can store it just about anywhere. Small cleaning closet? You’ll be good. You’ll have to put in the work, the bristles aren’t exactly fantastic and it’s not the best option for pet hair, but for some people, it will be the perfect fit.
There are definitely some tricks to making sure that you’ve handled pet stains and odors in the best way possible. There are also some homemade remedies which people recommend and some of them are super efficacious.
Clean furniture. Pet smells love to hide in furniture. Your cat’s special chair may be host to all sorts of irksome smells. The type of furniture will dictate the best cleaning method, but you should always check the care labels before cleaning to make sure the piece isn’t dry clean only. Care labels marked with an S mean don’t clean with water, and X means dry clean only.
UTIs can cause serious pregnancy complications, including premature labor, low birth weight, and sepsis infections. Hence, pregnant women should let their doctors know if they experience unpleasant-smelling urine, especially if the smell resembles ammonia.
If your home has pet odor problems, you’re in for one of the toughest odor removal projects known to man. That doesn’t mean you should give up hope. It just means that depending on the nature of the odor, and the material, this isn’t going to be an easy task.
I ran into a problem with my one dog going pee in the house and I knew something was wrong because I let her out every hour. So I ended up taking a urine sample to the vet and she had crystals in her urine which causes great pain in their bladder. The vet said it was like little pieces of glass in her bladder. I am treating her with Crananidin and Cosequin every other day because when so took it every day her poop was like soft serve ice cream. Works great no more pee in the house. Consult you vet for proper dosage. Nutramax pharm.
Excellent product. It is very effective at not only pet urine odors but also neutralizing human urine odor around toilets and urinals. It is by far the best product that I have ever used on cat urine.
I completely forgot that you can use a UV light to find stains in the carpet. My husband and I have noticed that our living room smells like our dog, so we are working on getting it cleaned up. I could use the light to spot clean, but I think it would be better to shampoo the entire room. Thanks for your advice about what products to try! http://www.prosteamplus.ca/cleaning_services.html
Understanding a little about the behavior and physiological capabilities of your pet helps in understanding why enzymatic cleaners are so useful for removing pet stains. Dogs and cats have a much more highly developed sense of smell than humans do and can detect odors that we cannot smell. We think the carpet is clean because the odor and stains are gone–and then the dog/cat returns and pees on the same spot.
When I moved into this house the carpets smelt of cat pee which 2 of my dogs peed over them, not wanting to change the carpets until I decorate I used a steam cleaner on them, my dogs no longer pee there and I can’t smell any either. May be worth a try with a steam cleaner. I have found the small hand held steam cleaners better than those for the floors.
I have 2 adult dogs and one just had a litter of 10 puppies, I have had to tear up the carpets in my home 3 times. I have only a center carpet left and now the smell of dog urine is back and I am done throwing out carpet. Please help to rid the smell and maybe some way to deture them from using the same spots all the time
In every second house people have their favorite pet and all of them from time to time cause problems which smell. Usually pets have a tray or they wait patiently when they will go for a walk. It happens quite often that the pet does not want to wait and behaves inappropriately: for some reason pees exactly on our new favorite carpet which we bought just recently or even received as a present from our grandmother. Anyone who was trying to get rid of pee smell and succeeded is getting pissed every time it is happening again. We will investigate best and simplest ways which remove urine properly.

CR’s take: This Hoover performs at two extremes. It gets the poorest marks for cleaning of all the carpet cleaners in our tests but one of the best scores for leaving behind a dry carpet, an Excellent. It does have some nice convenience features, such as separate tanks for clean and dirty water, a 100-inch hose, a carrying handle, and brush attachments. Unfortunately, features don’t make up for poor performance.
My doggy has had frequent accidents since we got her. I feel your pain! Instead of caging her at night, I started training her to sleep with me. I just put her leash around my ankle. I realized quickly that she wouldn’t tinkle on the bed, couch, or anytime she is leashed to me. My vet suggested this and it’s done wonders for my furry baby!!
UTIs tend to affect women and girls more, but men and boys can also develop UTIs. These infections are the result of bacteria entering the urinary tract. The bacteria make urine smell unpleasant and cause it to be cloudy or bloody.
Another cause for musty smelling urine is phenylketonuria or PKU. This is a genetic condition that causes the buildup of phenylalanine, an amino acid that cannot be processed, in the blood and even your brain. As this buildup continues unchecked, it could cause brain damage and must, therefore, be treated as soon as possible. Behavioral problems like tantrums, having fairer eyes, hair, and skin than siblings who don’t have the problem, vomiting, eczema, epilepsy, tremors and musty smelling breath are other signs of this ailment.13
Blue RARE: Artificial colors in foods or drugs; bilirubin; medications such as methylene blue; unusual UTIs Usually benign; consult your physician if it persists, especially if you have pain or burning (dysuria), and/or frequent urination (polyuria), which are symptoms of UTI

Important: It is better to wash the spot few times until you will use the carpet again. If the spot will remain smelling urine it will just attract dog and he will pee on the same spot again and again.
This will get rid of a great deal of the smell, but to really do a thorough job, you might want to rent a carpet cleaning machine with an attachment for furniture – or call a cleaning company to do it for you. Always start with neutralizing as much of the smell as possible before the shampooing, though, or all you will be doing is creating a hybrid of dog smell and perfumed shampoo. Not a good combination. And don’t use carpet shampoo on the furniture, or you could end up with ruined and smelly furniture.
