Urine composition and function. (2017, August 6). Retrieved from https://chem.libretexts.org/Textbook_Maps/Introductory_Chemistry_Textbook_Maps/Map%3A_Fundamentals_of_General_Organic_and_Biological_Chemistry_(McMurry_et_al.)/29%3A_Body_Fluids/29.8%3A_Urine_Composition_and_Function
The leading store-bought products made for removing the stain and smell of pet urine from carpets use the power of enzymes to do the work and are non-toxic for pets. Enzymes are proteins that help kick off natural chemical reactions at the molecular level, and the enzymes in pet carpet care products attach themselves to the molecules that make up the urine and bacteria that feed on it (producing the foul odors) and catalyze their breakdown.
Ah how I can relate to this scenario! After almost 30 foster dogs coming through my house (most not housebroken to start with) I know the battle with lingering odor well-and the frustration of having the dog go outside only to come in and find a blanket or rug to go on. And that feeling of never having your house clean! If none of the above cleaners work for you, you can always try a commercial product (of course natural is best!)-if you go that route I would recommend Biokleen Bac-out. I wish I had a magic solution, but cleaners aside, maybe I can offer some advice that can help.
Mix a solution of a hydrogen peroxide and dish detergent. Take about a half cup of peroxide and mix it with a spoonful of dish detergent. If using on a light-colored carpet, be sure to use a colorless dish detergent.
I just read this on the Humane Society’s website: Avoid using steam cleaners to clean urine odors from carpet or upholstery. The heat will permanently set the stain and the odor by bonding the protein into any man-made fibers.
Sophia: I really need to do something about this problem in the house we just moved into 3 weeks ago. Before we moved into this house we had the entire carpet professionally steam cleaned. The carpet cleaner could smell dog urine as soon as he came into the house (it was a rainy day). It has been three weeks and we still smell it in a couple of the rooms.

It takes three days to put one carpet cleaner through our battery of cleaning-performance tests. Our engineers soil large swatches of off-white nylon carpet with red Georgia clay. We run a cleaner over the carpet for four wet and four dry cycles, simulating how you’d clean a particularly dirty spot on a well-trafficked carpet. Then we repeat the test on two more swatches.
From sweet smelling pee that shrieks of uncontrolled diabetes to urine that smells strongly of ammonia due to urinary stones or musty due to liver trouble, the reasons for the change in the smell of your urine are numerous. At times, an unusual urine odor may also stem from underlying medical causes such as dehydration, UTIs, or maple syrup urine disease.
We have had our dog for 6 months now and have had trouble toilet training him. Our house stinks of urine. We had it professionally cleaned, but it still stinks. It obviously has gone right through to the underlay. What can we do?
Pet hair from dogs and cats can become embedded in carpet and is hard to remove even by vacuuming. To remove pet hair from carpeting, attach an old mop handle to a window squeegee, and use the rubber blade to rake up the pet hair.
I’ve been using the vinegar/water mix for years to rid the carpet of pet odors. It’s always worked well for me. I like the baking soda suggestion and if I get in a position where V/W doesn’t work, I’ll give it a try. Thanks for the suggestions Angie’s!

Act quickly! If you can get to the wee whilst it is still wet, the job is so much easier. If you can remove the majority of the urine right away, bacteria do not get a hold and it is the bacteria which cause the worst of the smell, not the urine itself.
If you used paper towels in your poultices, be sure to seal them in a garbage bag and get rid of them as soon as possible, so that your pet doesn’t try urinating on them, or digging them out of the garbage.
It does have some shortcomings: this product works best on fresh stains. If you’re moving into a former hoarder’s abode with crystallized urine and ruined floorboards then it’s not going to be sufficient but if things are in decent shape right now and you want to keep them that way it’s perfect.
Same here. My sweet 100 lb Boxer has cancer and hip dysplasia. I told my husband we will NOT get another dog (or inside animal) and we will replace the carpeting when she passes. Unfortunately, we still have to deal with grandbaby oopsies.
Really helpful! The light sounds especially useful, as I have mostly black and other dark fabrics. Accidents are hard to spot! Our dog doesn’t actually pee in the floor, he is just one of those dogs that sprinkles when he is happy (and excited, scared, upset, sleeping, etc!)
Most changes in urine odor are not a sign of disease and go away in time. Some foods and medicines, including vitamins, may affect your urine’s odor. For example, eating asparagus causes a distinct urine odor.

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 a female pitbull who is somewhat trained, and by that I mean she does well when I’m awake and goes to the restroom when I take her outside but during the night when I sleep she gets up without me noticing and uses the restroom on my carpet. She used to cry when she needed out but has recently stopped and left me with surprises in the morning. I’ve recently moved her to outside and I hate it because she is my sleeping buddy. What should I do?
You probably don’t give too much thought to your pee and what it looks and smells like. But if you’ve noticed a sudden change in the smell of that urine, you may want to know what’s causing it. Sometimes, it could be due to a health problem that may need the attention of a doctor, so don’t put off investigating this further. What follows are some symptoms to watch out for and the most common causes of smelly urine. However, there may be times that medication or certain health conditions unique to you are bringing on the problem. And that’s why it is critical that you let your doctor know if you spot anything amiss.
Steam-clean old stains. A rented cleaner can produce steam that’s hot enough to sanitize the carpet, after which the water can be vacuumed up again. Alternatively, if the spot is particularly large or stained, you can hire a professional cleaner to manage it.
Several vacuum brands sell smaller versions of wet-vacs for home use that retail between $150 and $200. These handy machines spray, brush and remove stains on their own and sell a version of their concentrated cleaner that’s formulated specifically to treat pet stains.
In the absence of other symptoms, such as pain with urination, cloudy or dark urine color, or unusual frequency of urination, there is usually little reason for concern. But reccurring ammonia odor in pregnancy should still be brought to a doctor’s attention.
He explains, “Sometimes it can be difficult to tell if a ‘fishy’ smell is coming from the urine or the vagina The most common cause of a fishy smell is usually related to common vaginal infections such as trichomoniasis, gardnerella, or bacterial vaginosis.”
“On the other hand, if you have carpeted stairs, you want to get a carpet cleaner that has a long hose, so you can reach up the steps,” says Larry Ciufo, who oversees Consumer Reports’ carpet cleaner tests. “You don’t want to put the cleaner on the top step and pull on the hose when you’re cleaning, because the machine could barrel down the steps.”
NO PADS. I believe in the old method of potty training their dogs to do their business outside. This should be done with the owner being consistent/persistent to properly train their pet. You have to be firm, not passive in your commands a method that is needed when they are initially trained. Please…no pads! They are not kids! They can tell by your tone whether they can get away with it or not…hence, firm but not passive! Do not be complacent…get up and do it and follow through on their potty training. It is your responsibility. You might also want to keep in mind that if they had another owner in the future, they would want them Properly trained.
Put a washable cover on furniture. Your pet may have proudly claimed an armchair or a spot on the couch as their own. This special space, or any other furniture where your pet lounges, will need frequent washing to keep the odors at bay. If your pets spend a lot of time on your furniture, it’s a good idea to invest in washable covers like slip covers. That way, you don’t have to worry about the hassle of vacuuming and scrubbing your furniture. Instead, just throw the cover in the wash.
Does anybody have any suggestions on how to remove odor from hardwood floors? We have 3 shih-tzus and 2 of them are 8 years and do have accidents. One of them is very overweight and I’m starting to suspect possible diabetes. She is going to vet this week. The male will go when we leave sometimes. I believe he gets mad at us for leaving him!!! We also have a 5 year old male that WILL NOT go in the house unless he is sick. The big difference is my husband and I were both working when we got the 2 eight year olds as puppies. I was not working when we got the 5 yr old and he was potty trained in less than 2 weeks!!! Lesson learned!!!
5. Super easy to clean for storage after use . The machine comes apart very easy and it is also easy to remove the beater bar/brush on the floor/front and rinse it out to remove all of that cat/dog hair from my many pets. I have A LOT of hair each time I use it. Simply run it under the faucet and everything rinses out. It also tells you in the instructions to use it with hot water cycle through at the end before you store it for a long period of time. I do this with my Little Green Machine, too, but not quite what they are telling you to do, so don’t do what I do because it isn’t what they are telling you to do. I set a bowl in the sink, turn the faucet on to hot tap water, run the water in the bowl, then stick the nozzle into the bowl and let it suck up clean water until the tank fills-empty, repeat, empty repeat, until the dirty water tank is running clear. That gets the soap and residue out of the lines along the way on both my Little Green as well as this machine, using the hand held hose attachment. You can remove the beater bar VERY EASILY and run it under the faucet to clear it from the soap, hair, etc. It only weighs 2 pounds, tops. Super easy to clean.
It’s also important to consider your dog’s motivations for peeing inside. Sometimes, inappropriate elimination is a sign of a medical issue. It can also indicate anxiety or emotional distress. If your dog is peeing indoors, start with a vet visit to rule out physical causes.
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.
If the extent of your pet odor problem is just a general pet smell (not urine), you’ve just encountered a best-case-scenario when it comes to pet odor removal. It’s not pleasant, and it’s still going to take some work to remove the odor from your home, but there are a number of pet odor removal solutions out there to take advantage of.
I have tried the Baking soda and Vinegar mixture, because the smell was horrid…. I let it dry several hours and i can still smell the urine…. Is there anything else i can do? i need a shampooer but do not have one at the moment… Please Help!
Limit your caffeine and alcohol intake, which can irritate the lining of your bladder. Make sure your diet has plenty of magnesium, and avoid sugar (including fructose and soda) and non-fermented soy products due to their oxalate content. Finally, don’t hold it. As soon as you feel the urge to go, go! Delaying urination is detrimental to the health of your bladder due to overdistension.
I had this same problem with my elderly miniature poodle. The only thing that has worked is a mild sedative, Acepromazine, at bedtime and putting a diaper on her. I might have to keep a diaper on her 24/7 because even though I watch her almost continually she still urinates in the house occasionally. The night time solution came after consultation with her vet. I never tried putting her in a crate, beside the bed at night, this might work. Since your dog is young as compared to my 15 year old dog, I would try the crate thing first. Good luck!

Let’s face it: Most of us don’t give much thought to our pee before we flush it out of sight. But the basic details of your urine — color, smell, and how often you go — can give you a hint about what’s going on inside your body.
Jothan Hatch, the national training director for Chem-Dry carpet cleaning, has a puppy named Koda who’s still perfecting potty training. Sometimes, when he gets over-excited, he “leaks,” says Hatch. Fortunately, Hatch knows a bit about rescuing rugs.

Also, not a “defect” but something you need to know if you’re like me and tend to lift up the handle to pick up the whole machine (like you would w/ a vacuum cleaner) to lift it over the power cord, when I lifted the handle on this carpet cleaner the water container lunged out from the machine! It seems that this is quick release mechanism! Good to know, at least the water tank didn’t have very much in it so nothing spilled, whew, that was exciting, and not in a good way!

What you are smelling may just be her natural dog odor once the shampoo’s fragrance has worn off. If it smells like it’s something else, try to figure out if she is getting into something that gives her that smell.
