Do Enzymes Really Work on Dog Urine

Are you tired of your furry friend leaving their mark all over your carpets and furniture? Have you tried every DIY solution out there, but still can't get rid of the lingering smell of dog urine? Well, fear not! In this blog post, we're going to dive into the world of enzymes and explore whether they truly work on dog urine. From how enzymes break down stains to the best enzymatic cleaners on the market, we've got you covered. 

Enzymes in Dog Urine

Enzymes are proteins that catalyse chemical reactions in the body. Enzymes in dog urine help to break down the urea and uric acid in urine so that it can be more easily excreted. Dogs with normal kidney function typically have high concentrations of enzymes in their urine. However, dogs with kidney disease or other health conditions may have lower levels of enzymes in their urine. Enzymes may also be present in dog urine if a dog has recently been treated with antibiotics.

How Enzymes Work on Dog Urine

All living cells produce enzymes as part of their metabolic processes. Enzymes are proteins that act as catalysts, speeding up chemical reactions in the body. Enzymes are specific to the reactions they catalyse and are not used up in the process.Dog urine contains enzymes that break down the urea in urine into ammonia and carbon dioxide. This process is known as urea hydrolysis. The enzymes responsible for this reaction are urease enzymes. Urease enzymes are found in many bacteria, fungi, and plants, but not in mammals.When dog urine containing urease comes into contact with grass, the urea is hydrolysed into ammonia and carbon dioxide. Ammonia is a nitrogen-containing compound that is very toxic to plants. And carbon dioxide is produced as a waste product of this reaction.The high levels of ammonia in dog urine can damage grass, making it yellow and brown. The carbon dioxide produced by the enzymatic reaction can also contribute to the death of grass by suffocating the roots.

Do Enzymes Really Work?

There are a lot of products out there that claim to be effective cleaners for dog urine and odours with the power of enzymes. But do enzymes really work?The short answer is: yes, enzymes do work on dog urine. But there are a few things you need to know in order to get the best results.Enzymes are proteins that catalyse chemical reactions in the body. They can be found in all sorts of places, from the digestive system to the immune system. Enzymes are also found in many cleaning products, including those designed to remove pet stains and odours.When it comes to cleaning up dog urine, enzymes work by breaking down the proteins and other organic compounds that make up the stain. This process is known as hydrolysis. By breaking down these compounds, enzymes effectively remove the stain and odour from surfaces like carpets, upholstery, and clothing.

There are a few things you should keep in mind if you're looking to use enzymes to clean up dog urine stains:

  1. Enzymes are most effective when used on fresh stains. The longer a stain sits, the more time it has to set into fabrics and surfaces. So if you can, act quickly!
  2. Be sure to follow the product's instructions carefully. Different enzyme cleaners have different directions for use, so it's important that you read and follow them closely in order to get the best results

The Pros and Cons of Using Enzymes on Dog Urine

There are a number of enzymatic cleaners on the market that claim to remove pet stains and odours. So, let's take a look at the pros and cons of using enzymes on dog urine.


  1. Enzymes are natural and safe for both humans and pets.
  2. They are effective at breaking down uric acid, which is the main component of dog urine.
  3. Enzymatic cleaners can be used on both carpets and upholstery, making them versatile.
  4. They are typically less expensive than other types of cleaners.


  1. Enzymatic cleaners can take longer to work than other cleaners, so you may have to wait longer for results.
  2. Some dogs may be allergic to enzymes, so it's important to test a small area first before using them more broadly.
  3. If not used properly, enzymatic cleaners can actually make pet stains and odours worse by encouraging resoiling.


Enzymes can be an effective tool in tackling dog urine odours and stains. They are cost-effective, easy to use, and generally safe for most surfaces. Remember that it’s important to always check the safety of any product you use on your pet's urine prior to using it. 

With these tips in mind hopefully, you can keep your home free of dog urine odour and stains.
