What to consider for Dog Poop Bags For Dogs Under 20 Lbs

Small dogs produce smaller waste, so standard large bags can be wasteful and cumbersome. Look for bags sized around 9×13 inches or smaller. Thickness matters to prevent leaks and tears; aim for at least 1.0 mil. Eco-friendly materials like compostable or recycled options are popular, but ensure they meet ASTM D6400 standards for compostability. Handles and easy-tie features add convenience, and unscented bags are better for sensitive noses.

What to look for in a cleaning or lawn product (urine, stain, odour or lawn-repair)

For cleaning up after small dogs, genuine enzymatic cleaners break down urine and odour at the molecular level. Look for products labeled pet-safe once dry, as small dogs may lick treated areas. For outdoor use, lawn-safe formulations prevent yellow spots and are non-toxic to grass. Avoid products with ammonia, which can attract dogs to re-mark, and always check that the product is specifically designed for pet stains and odours.

How we chose these picks

We reviewed customer ratings and reviews on Amazon for bags specifically marketed for small dogs.
We prioritized bags with a size under 9×13 inches to reduce waste and fit small dog waste.
We evaluated thickness and leak-proof claims, favoring bags with at least 1.0 mil thickness.
We considered eco-friendly materials like compostable or recycled content, checking for certifications.
We looked for practical features like handles, easy-tie closures, and unscented options.
We compared price per bag to identify budget-friendly choices without sacrificing quality.

Never ranked a product higher just because it pays a commission.

What to avoid

Avoid ammonia-based cleaners for indoor accidents; the smell can encourage dogs to re-soil the area.
Steer clear of products not labeled pet-safe, as residues may harm small dogs if ingested.
Do not use harsh lawn chemicals like fertilizers with high nitrogen content where dogs play before they dry, as they can burn paws and cause digestive issues if licked.

Why this matters

Small dog owners often overlook bag size, but using standard large bags for dogs under 20 lbs creates unnecessary plastic waste and can be awkward to handle. Switching to a 9x13 inch bag reduces waste by up to 30% while maintaining easy cleanup.

The Options

Types Explained

Standard Plastic Bags

Made from polyethylene, these are the most common and affordable. They are durable and leak-proof but not biodegradable. Suitable for daily use where eco-friendliness is not a priority.

Best for: Budget-conscious owners who prioritize strength and reliability.

Compostable Bags

Made from plant-based materials like cornstarch, these bags break down in commercial composting facilities. They are eco-friendly but may be less durable and more expensive. Check for ASTM D6400 certification.

Best for: Environmentally conscious owners who have access to composting facilities.

Recycled Plastic Bags

Made from post-consumer recycled plastic, these reduce waste. They offer similar durability to standard plastic but may have a slightly different texture. Not compostable.

Before You Buy

Key Buying Factors

Size Matters

For dogs under 20 lbs, standard 9x13 inch bags are ideal. They reduce plastic waste and are easier to handle. Avoid oversized bags that are cumbersome and wasteful.

Thickness and Durability

Look for bags with a thickness of at least 1.0 mil to prevent tearing and leaks. Thicker bags (1.2 mil or more) offer extra security but may cost slightly more.

Eco-Friendly Materials

Compostable bags made from plant-based materials are better for the environment, but ensure they meet ASTM D6400 standards. Recycled plastic bags are another greener option, though they may be less durable.

Scent vs Unscented

Unscented bags are generally preferred to avoid overwhelming a dog's sensitive nose. Scented bags can mask odours but may attract some dogs or cause allergies in sensitive pets.

Handles and Dispensers

Bags with built-in handles make tying and carrying easier. A dispenser that attaches to a leash or belt adds convenience for walks. Check if the bag roll fits standard dispensers.

Living With It

Care, Cost and Maintenance

Proper Disposal

Always dispose of poop bags in designated trash bins. Do not flush them, even if labeled flushable, as they can clog plumbing. For compostable bags, ensure they go to a commercial composting facility, as they may not break down in home compost piles.

Storage Tips

Store bags in a cool, dry place away from direct sunlight to prevent degradation. Keep them in a dispenser or original packaging to avoid tearing. If using scented bags, seal them tightly to preserve the fragrance.

Handling Accidents

For indoor accidents, use an enzymatic cleaner to break down stains and odours. Avoid using ammonia-based products. For outdoor cleanup, pick up waste promptly to prevent lawn damage and reduce the risk of parasites.

Pro tip

To make walks easier, pre-load a few bags into a small dispenser that clips to your leash. This way you're never caught without a bag, and you can quickly grab one without fumbling.

Frequently asked questions

How do enzyme cleaners work for dog poop stains?

Enzyme cleaners contain beneficial bacteria that produce enzymes to break down organic waste like feces and urine into simpler, non-smelly compounds. The enzymes digest the proteins and fats, eliminating the stain and odour at the source. For best results, apply the cleaner to the affected area, let it sit for the recommended time (usually 5 to 15 minutes), then blot or rinse. Enzyme cleaners are effective on both fresh and set-in stains, though older stains may require multiple applications. They are safe for use on most surfaces, including carpets, hardwood, and tile, but always test in an inconspicuous area first.

Are enzyme cleaners safe for my small dog?

Yes, when used as directed and allowed to dry completely, enzyme cleaners are generally safe for dogs. The enzymes are non-toxic and biodegradable. However, you should keep your dog away from the treated area until it is dry to prevent ingestion of wet cleaner. Avoid products with added fragrances or harsh chemicals that could irritate sensitive skin. Always check the label for pet-safe certification. If your dog has a history of allergies or sensitivities, consult your veterinarian before using a new cleaner. Ingesting small amounts of dried residue is unlikely to cause harm, but it's best to prevent licking.

Can enzyme cleaners remove set-in dog poop odours?

Enzyme cleaners can remove set-in odours, but it may take multiple applications and patience. The enzymes need to penetrate the fibres to reach the source of the smell. For deep-set odours, saturate the area thoroughly and allow it to air dry. You may need to repeat the process 2 to 3 times. Avoid using steam cleaners or hot water, as heat can denature the enzymes and render them ineffective. For carpets, consider using a carpet cleaner machine with an enzyme solution. If the odour persists, the waste may have soaked into the padding or subfloor, requiring professional cleaning or replacement.

How do I repair yellow spots on my lawn caused by dog urine?

Yellow spots are caused by high nitrogen concentration in urine. To repair, first flush the area with water to dilute the nitrogen. Then apply a lawn repair product containing gypsum or a specialized pet-safe lawn treatment. You can also overseed the patch with grass seed and cover with topsoil. For prevention, train your dog to urinate in a designated area with gravel or mulch, or use dietary supplements that reduce nitrogen content. Avoid using fertilizers high in nitrogen near the treated area. Regular watering helps dilute urine and prevent spots.

Are enzyme cleaners safe for carpets and hard floors?

Yes, enzyme cleaners are safe for most carpets and hard floors, including tile, laminate, and hardwood, provided they are labeled for that surface. Always test in a hidden area first. For carpets, blot up excess moisture and avoid over-wetting to prevent mould. For hardwood, use a cleaner specifically formulated for wood to avoid damage. Avoid using enzyme cleaners on unsealed wood or delicate fabrics. After cleaning, ensure the area is well-ventilated to speed drying. If you have pets that are prone to licking floors, choose a non-toxic, pet-safe formula.

Can I use enzyme cleaners around my dog while they are still wet?

It is best to keep your dog away from the area until the cleaner is completely dry. Wet enzyme cleaners can be ingested if your dog licks the surface, which may cause mild gastrointestinal upset. Additionally, some dogs may be attracted to the scent of the cleaner. To be safe, confine your dog to another room or use a pet gate. Allow the cleaner to dry for the time specified on the label, usually 1 to 2 hours. For carpets, you can speed drying with a fan. Once dry, the residue is safe and non-toxic.

Can I use enzyme cleaners in a carpet cleaning machine?

Yes, many enzyme cleaners are compatible with carpet cleaning machines. Check the label to ensure it is suitable for use in extractors. Typically, you add the cleaner to the machine's solution tank and follow the machine's instructions. Avoid using hot water, as heat can deactivate enzymes. Use cool or warm water instead. After cleaning, run a rinse cycle with plain water to remove any residue. Enzyme cleaners can help remove deep-set pet stains and odours when used in a machine, but you may need to pre-treat stubborn spots first.

What should I do if my dog ingests an enzyme cleaner?

If your dog ingests a small amount of enzyme cleaner, it is usually not toxic, but it may cause mild vomiting or diarrhea. Remove your dog from the area and offer fresh water. Do not induce vomiting unless directed by a veterinarian. Contact your veterinarian or a pet poison helpline for advice. Have the product label handy to provide information on ingredients. If your dog shows signs of distress, such as excessive drooling, lethargy, or difficulty breathing, seek emergency veterinary care immediately. To prevent ingestion, always store cleaners out of reach and keep pets away during application.

Are there any safety concerns with using enzyme cleaners around small dogs?

Enzyme cleaners are generally safe for small dogs when used correctly. However, small dogs may be more sensitive to chemicals due to their size. Choose a product that is specifically labeled pet-safe and free from harsh additives. Ensure the area is well-ventilated during and after cleaning. Avoid using enzyme cleaners on surfaces where your dog eats or sleeps until dry. If your dog has a history of allergies, consult your vet before use. Always supervise your dog after cleaning to prevent licking of wet surfaces. With proper use, enzyme cleaners are a safe and effective solution for pet messes.

A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
