Quick Comparison

Quick answer

For dogs under 20 lbs, the Rocco & Roxie Stain & Odor Eliminator is our top pick for cleaning up accidents. Its enzymatic formula breaks down urine and removes odors effectively. However, if you need a gate specifically, the Carlson Pet Gate is a great budget-friendly option for small dogs.

What to consider for Dog Gate For Dogs Under 20 Lbs

When choosing a gate for small dogs under 20 lbs, consider the gate’s height and bar spacing. Small dogs can squeeze through wide gaps, so look for bars spaced 2 inches or less. Also, ensure the gate is sturdy enough to prevent tipping, but lightweight for easy operation. Pressure-mounted gates work well for doorways, while hardware-mounted gates are better for stairs.

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

For cleaning up after your small dog, look for genuine enzymatic cleaners that break down urine proteins and eliminate odors at the source. Ensure the product is labeled pet-safe once dry, and check for proven effectiveness on stains and smells. For lawn products, choose formulations that are lawn-safe and won’t kill grass.

How we chose these picks

  • We evaluated products based on publicly available information and established guidance.
  • We prioritized enzymatic cleaners that effectively break down urine and odors.
  • We considered pet safety, ensuring ingredients are non-toxic when used as directed.
  • We looked for products with positive reviews and proven track records.
  • We compared price points to offer options for different budgets.
  • We selected products suitable for various surfaces including carpets, hard floors, and lawns.
  • We ensured all picks are widely available on Amazon.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • Avoid ammonia-based cleaners; the smell attracts dogs back to the same spot.
  • Do not use products not labeled pet-safe, as they may contain harmful chemicals.
  • Steer clear of harsh lawn chemicals that can harm dogs if they play on the grass before it dries.

For dogs under 20 lbs, choose gates with bar spacing of 2 inches or less to prevent squeezing through.

04

Height

A gate height of at least 30 inches is recommended to prevent small dogs from jumping over.

Living With It

Care, Cost and Maintenance

Regular Cleaning

Wipe down the gate with a mild soap and water solution to remove dirt and pet hair. Avoid harsh chemicals that may damage the finish.

Check Hardware

Periodically inspect screws and mounting brackets for tightness. Tighten any loose parts to maintain stability.

Lubricate Hinges

Apply a silicone-based lubricant to hinges and moving parts to keep the gate operating smoothly.

Pro tip

To prevent your small dog from jumping over the gate, choose a gate that is at least 30 inches tall and avoid placing furniture nearby that could be used as a launch pad.

Frequently asked questions

How do enzyme cleaners work?
Enzyme cleaners contain beneficial bacteria that produce enzymes to break down organic matter like urine, feces, and vomit. The enzymes digest the proteins and other components, effectively removing stains and odors at the molecular level. This process continues as long as the enzymes are active, making them highly effective for pet messes.
Are enzyme cleaners safe for pets?
Yes, when used as directed, enzyme cleaners are safe for pets. Most are non-toxic and biodegradable. However, always keep pets away from the area until the product has dried completely to avoid ingestion of wet chemicals. Check the label for specific safety instructions.
How do I remove set-in urine odor?
For set-in odors, first saturate the area with an enzymatic cleaner. Allow it to dwell for the recommended time (often 10-15 minutes) to let the enzymes work. Blot up excess liquid, then let it air dry. Repeat if necessary. For deep-set odors in carpet padding, professional cleaning may be needed.
Can I repair yellow spots on my lawn from dog urine?
Yes, lawn repair products like Skout's Honor Probiotic formula can help. They contain beneficial microbes that break down the urea in urine, reducing nitrogen burn. Water the area thoroughly after application to dilute the urine. Consistent use can help restore grass health.
Is it better to use enzyme cleaners on carpet or hard floors?
Enzyme cleaners work well on both, but hard floors are easier to clean because liquids don't soak in. On carpets, the cleaner penetrates fibers and padding, making it effective for deep odors. For hard floors, use a mop or spray and wipe method.
How can I use cleaning products safely around my dog?
Always read and follow label instructions. Keep your dog away from the treated area until it is completely dry. Use products labeled as pet-safe. Avoid ammonia-based cleaners, as they can be harmful and attract dogs to re-mark the spot.
Can I use enzyme cleaners in a carpet cleaning machine?
Some enzyme cleaners are safe for use in carpet cleaning machines. Check the product label to ensure it is compatible. Generally, you can add the cleaner to the machine's solution tank and follow the manufacturer's instructions for spot cleaning or whole room cleaning.
What should I do if my dog ingests a cleaning product?
If your dog ingests a cleaning product, contact your veterinarian or a pet poison control center immediately. Have the product label handy to provide ingredient information. Do not induce vomiting unless instructed by a professional.
Are there any safety concerns with using enzymatic cleaners around children?
Enzymatic cleaners are generally safe around children once dry. However, keep children away from the area during application to avoid slipping or contact with wet chemicals. Store all cleaning products out of reach of children and pets.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your pet's diet or care routine, especially if your pet has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
