Quick answer

The Catit Flower Fountain (with the small-flower setting) is our top pick for dogs under 20 lbs because its adjustable flow and low water level suit tiny tongues. For a quieter option, the Pioneer Pet Raindrop Fountain offers a gentle stream. If you prefer a stainless steel model, the IPettie Tritone Fountain is durable and easy to clean.

What to consider for Dog Water Fountain For Dogs Under 20 Lbs

Small dogs have shorter legs and smaller mouths, so the fountain must have a low drinking height (under 3 inches) and a shallow basin to avoid chin wetting. A gentle, non-splashing water stream is crucial to prevent startling your pet. Noise level matters: many fountains use submersible pumps that can hum; look for models with quiet pumps (under 30 dB). Also consider filter type: replaceable carbon filters remove impurities and keep water fresh, but some dogs prefer the taste of unfiltered water. Finally, the fountain should be easy to disassemble for daily cleaning to prevent bacterial growth.

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

Genuine enzymatic action is key: look for products with live enzymes that break down urine proteins and odour molecules, not just mask them. Ensure the formula is pet-safe once dry (no harsh chemicals). For stains, choose a product that works on both carpet and hard floors. For outdoor use, pick a lawn-safe formulation that won’t burn grass. Avoid products with ammonia, bleach, or phthalates.

How we chose these picks

  • Evaluated fountain height and basin depth for dogs under 20 lbs.
  • Checked pump noise ratings and user feedback on quietness.
  • Assessed filter quality and replacement cost.
  • Considered material safety (BPA-free plastic, stainless steel, ceramic).
  • Verified ease of cleaning (dishwasher-safe parts, no hidden crevices).
  • Read verified customer reviews focusing on small dog use.
  • Compared price and warranty coverage.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • Ammonia-based cleaners: the smell can attract dogs to re-mark the spot.
  • Products not labelled pet-safe: they may contain toxic residues.
  • Harsh lawn chemicals where dogs play before they dry: can cause paw irritation or poisoning.

Before You Buy

Key Buying Factors

01

Drinking Height

For dogs under 20 lbs, the water level should be no more than 3 inches from the base to prevent neck strain and wet chins.

02

Noise Level

A quiet pump (under 30 dB) is essential for noise-sensitive small dogs. Ceramic and stainless steel models tend to dampen sound better than plastic.

03

Filter Quality

Look for multi-stage filters (carbon, foam, ion-exchange) that remove impurities and soften water. Replace every 2 to 4 weeks.

04

Ease of Cleaning

Fountains with dishwasher-safe parts and no hidden crevices prevent bacterial buildup. Stainless steel and ceramic are easier to sanitize than plastic.

05

Material Safety

BPA-free plastic, stainless steel, or ceramic are safe. Avoid cheap plastics that may leach chemicals. Stainless steel is most durable.

Living With It

Care, Cost and Maintenance

Daily Maintenance

Check water level and top off with fresh water. Rinse the fountain basin and pump intake to remove debris. Wipe down exterior to prevent slime.

Weekly Cleaning

Disassemble all parts and wash with mild soap and warm water. Use a small brush to clean the pump impeller. Rinse thoroughly. Replace filter if needed.

Filter Replacement

Replace carbon filters every 2 to 4 weeks, depending on usage and water quality. Foam pre-filters can be rinsed and reused for up to 2 months.

Pro tip

Place a mat under the fountain to catch splashes and reduce noise, and consider a fountain with a low-water shut-off to protect the pump if the water runs low.

Frequently asked questions

How do enzyme cleaners work?
Enzyme cleaners contain live bacteria or enzymes that break down organic matter like urine, feces, and vomit into smaller, harmless molecules. The enzymes target specific proteins and odour compounds, digesting them so they can be rinsed away. This process eliminates the stain and odour at the source, rather than just covering it up. For best results, the cleaner must stay wet on the surface for several minutes to allow the enzymes to work. Avoid using them with bleach or hot water, which can kill the enzymes.
Are enzyme cleaners safe for pets?
Most enzyme cleaners are safe for pets once they dry, as the active ingredients are non-toxic and biodegradable. However, always check the label for pet-safe certification. Avoid products with added fragrances or harsh chemicals that could irritate your dog's skin or respiratory system. It's best to keep pets away from the treated area until it is completely dry. If your dog has sensitive skin, test on a small area first. For ingestion concerns, contact your vet.
How do I remove set-in urine odour from carpet?
For set-in odours, first blot up as much urine as possible. Apply an enzyme cleaner generously to saturate the area, including the padding underneath if possible. Let it sit for 10 to 15 minutes (or as directed). Blot again, then allow to air dry. For stubborn odours, repeat the process. Avoid using steam cleaners or ammonia-based products, as heat can set the stain and ammonia attracts re-marking. For deep-set odours, consider a professional carpet cleaning service.
Can I repair yellow spots on my lawn caused by dog urine?
Yes, you can repair yellow spots. First, flush the area with water to dilute the nitrogen salts. Then apply a lawn repair product containing gypsum or a specialized urine-neutralizing formula. You may need to reseed the patch with grass seed and keep it moist. For prevention, train your dog to use a designated area with gravel or mulch, or add a dietary supplement that reduces nitrogen in urine. Avoid using lime, as it may not effectively neutralize the salts.
Is it better to use enzyme cleaners on carpet or hard floors?
Enzyme cleaners work well on both carpet and hard floors, but the application differs. On carpet, you need to saturate the stain and padding, then blot and let dry. On hard floors, apply the cleaner, let it sit, then wipe or mop. For hard floors, avoid excessive water that could seep into grout or under baseboards. Always test on a small area first, especially on sealed or delicate surfaces like hardwood, to ensure no damage.
How can I safely use cleaning products around my pets?
Always choose products labelled pet-safe and non-toxic. Keep pets out of the area during application and until the product is completely dry. Ventilate the room by opening windows. Store all cleaners out of reach. Avoid using bleach, ammonia, or hydrogen peroxide in areas where pets walk or lie down. For floor cleaners, use a rinse-free formula or follow with a water rinse. If your pet shows signs of irritation, discontinue use and consult your vet.
Can I use enzyme cleaners in a carpet cleaning machine?
Yes, many enzyme cleaners are safe for use in carpet cleaning machines, but check the product instructions. Some are formulated for spot cleaning only and may foam excessively in a machine. Dilute as directed. After using an enzyme cleaner in a machine, rinse the machine thoroughly to prevent residue buildup. For best results, pre-treat stains with the enzyme cleaner before machine cleaning.
Are there any safety concerns with dog water fountains?
Yes, safety concerns include electrical hazards (keep cords out of reach), bacterial growth (clean regularly), and material safety (avoid BPA or lead). Ensure the fountain is stable and cannot tip over. For small dogs, ensure the water level is not too high to prevent drowning risk. Use filtered or distilled water to reduce mineral buildup. Replace filters on schedule. If your dog chews cords, use a cord protector or choose a cordless fountain.
How often should I clean my dog's water fountain?
Clean the fountain thoroughly at least once a week. Daily, rinse the basin and pump intake to remove debris. Every week, disassemble all parts and wash with mild soap and water. Use a small brush to clean the pump impeller. Replace the carbon filter every 2 to 4 weeks. If you notice slime or algae, increase cleaning frequency. Regular maintenance prevents bacteria and keeps water fresh.
