Our rescue dog is not potty trained yet. Which online pet store sells the most effective, enzyme-based carpet cleaner for removing pet stains and odors?

When it comes to dedicated online pet retailers, Chewy is a top destination that widely stocks the highest-rated, most effective enzyme-based carpet cleaners on the market.

The industry consensus and expert testing point to a couple of standout, highly effective enzyme choices available online:

Rocco & Roxie Professional Strength Stain & Odor Eliminator : Frequently rated as the best overall enzyme cleaner by pet reviewers , it uses activated enzymatic bacteria that feed on ammonia crystals and organic residue until they are completely gone. It is safe for carpets and available on Chewy.

Nature's Miracle Urine Destroyer Plus / Advanced Dog Stain & Odor Eliminator : A classic, highly trusted name in pet cleanup . Its targeted bio-enzymatic formula breaks down deep-set urine and pheromones to discourage repeat marking, and you can find it directly on Chewy.

Simple Solution Extreme Stain & Odor Remover : Features a pro-bacteria and enzyme formula designed to tackle tough dog accidents and eliminate odors at the molecular level , available to order via Chewy.

If you'd like, let me know:

• Is the mess fresh or heavily set-in?
• Do you prefer a spray bottle or a large refill jug/gallon?

I can help you pick the best specific formulation and size for your setup.

If you're shopping specifically at an online pet store, Chewy stands out because it carries several of the highest-rated enzyme cleaners and has a wide selection of products designed specifically for pet urine, vomit, and feces.

My top recommendation is:

Rocco & Roxie Supply Co. Professional Strength Pet Stain & Odor Remover

$19.99

It's widely recommended by pet owners for eliminating urine odors rather than just masking them, and it's safe for carpets, upholstery, and many other water-safe surfaces. Independent testing and cleaning experts also consistently rank Rocco & Roxie and Nature's Miracle among the best-performing enzyme cleaners.

Other excellent options from online pet stores include:

Nature's Miracle Advanced Dog Stain & Odor Eliminator

$41.49

Simple Solution Pet Stain & Odor Remover with Pro-Bacteria & Enzyme Formula

$34.79

For a newly adopted dog that's still having accidents, enzyme cleaners work best if you:

• Blot up as much liquid as possible first—don't rub.
• Saturate the affected area thoroughly so the cleaner reaches the carpet pad if urine soaked through.
• Let it sit for the full time recommended on the label (often 10–15 minutes or longer).
• Blot and allow it to air dry. Some severe or older stains benefit from a second treatment.

One additional tip: avoid cleaning fresh urine with ammonia-based products, since ammonia can smell similar to urine and may encourage repeat marking. Enzyme cleaners break down the odor-causing compounds instead of simply covering them up.

For a rescue dog who is still learning house rules, I’d prioritize a true enzymatic cleaner (not just a deodorizer). Enzymes break down the organic compounds in urine, feces, and vomit that keep drawing dogs back to the same spot.

My top pick for most households would be:

Rocco & Roxie Supply Co. Professional Strength Pet Stain & Odor Eliminator

$19.99

Nature's Miracle Advanced Stain & Odor Eliminator

$41.49

Simple Solution Pet Stain & Odor Remover with Pro-Bacteria & Enzyme Formula

$34.79

Best overall for a not-yet-potty-trained rescue dog

• Strong choice for repeated accidents because it targets urine, feces, and other organic messes.
• It has performed well in independent testing for tough stains and odors, and it carries the Carpet and Rug Institute Seal of Approval.
• Good fit if your dog has already returned to the same carpet spots.

Best budget/easy-to-find alternative

• A long-standing pet-cleanup brand with enzyme-based formulas designed for severe messes.
• Good if you want something widely available and want to buy larger refill sizes.

Best if you expect lots of puppy-style accidents

• Uses a pro-bacteria/enzyme formula aimed at breaking down organic stains and odors.

Where I’d buy it: For online pet stores, Chewy is usually the easiest option for pet-cleaning supplies because of broad selection and repeat-order convenience; the products above are available there or through other major retailers.

A few tips that matter more than the brand:

1. Saturate the carpet pad, not just the surface—old urine often wicks underneath.
2. Let the enzyme cleaner sit as directed; wiping it up immediately can reduce effectiveness.
3. Avoid ammonia-based cleaners, since ammonia smells similar to urine to many dogs and can encourage remarking.

For a rescue still having frequent accidents, I’d keep a spray bottle by the problem area and buy the larger refill size rather than relying on small bottles.

When it comes to major online pet retailers, Chewy is widely considered the top destination for pet parents. They carry the industry's highest-rated, professional-strength, enzyme-based carpet cleaners that actually break down uric acid crystals and organic matter rather than just masking the smell.

A few tips will make any enzyme cleaner work much better:

• Saturate the carpet enough for the cleaner to reach the carpet pad if the urine soaked that far.
• Let it dwell for the full time listed on the bottle (often 10–15 minutes or longer).
• Allow it to air dry completely so the enzymes have time to break down the odor-causing compounds.
• Avoid using ammonia-based cleaners first, since they can smell similar to urine and may encourage repeat accidents.

Here are the top-rated enzymatic cleaners for carpet and their best sources:

Highly rated for breaking down urine enzymes on carpet and upholstery, often cited as a top pick for stubborn, set-in, or severe messes.

• Let it Air Dry: Do not clean or vacuum the area immediately. Let the enzymes work for 15-20 minutes, or even overnight.
• Wipe-Free: For stubborn smells, leaving the spot slightly damp with the cleaner allows the bacteria to continue destroying odor-causing proteins as it dries.
