Best Potty Trainers for Puppies: Trays, Sprays, and Doorbells
The best potty trainer for a puppy depends on whether you need an indoor toilet spot, an outdoor signal, or help directing your puppy to the right place. The UPIT mesh tray is best for small puppies using pads, while Nature’s Miracle and NaturVet sprays help mark a chosen potty area. ChunHee and COOYOO doorbells are better for puppies learning to signal that they need to go outside.
| Product | Best suited for | Training role |
|---|---|---|
| UPIT Puppy Potty Tray | Small puppies using pads indoors | Pad holder with mesh grate |
| Nature’s Miracle Spray | Indoor or outdoor spot training | Potty-location attractant |
| NaturVet Potty Here Spray | Pad, artificial grass, or outdoor training | Potty-location attractant |
| ChunHee Dog Training Bells | Teaching a puppy to signal at a door | Electronic doorbell |
| COOYOO Dog Doorbells | Adjustable, hanging-bell training | Door or wall signal |
UPIT Puppy Potty Tray With Mesh

This plastic tray measures 20 by 16 inches and is designed for small dogs and puppies. Its perforated mesh lets urine pass through to a training pad underneath, helping keep paws away from the wet pad. The snap-on/off grate also makes it harder for puppies to reach and shred the pad.
Best for: Small puppies whose owners want a defined indoor potty area and added protection for pee pads. The sturdy PP plastic construction and leak-proof tray design make it a practical choice for pad-based training.
Consider: The listed size is small, so check the available floor space and your puppy’s size before choosing it. This is a tray for indoor pad use, not a bell or location-training spray.
Nature’s Miracle Advanced Platinum Training Spray

This 8-ounce spray is made to encourage puppies to go where it is applied. The listed formula is intended for indoor and outdoor training and can provide up to 12 hours of effect when used as directed.
Best for: Owners who want to designate a potty spot without using a tray or bell. It can complement a puppy’s regular routine by making the chosen area the target for training.
Consider: The up-to-12-hour duration depends on using the product as directed. A spray provides a location cue; it does not replace taking the puppy to the spot consistently.
NaturVet Potty Here Training Aid Spray

NaturVet’s 8-ounce liquid spray uses an attractant scent to encourage dogs to urinate where it is sprayed. The product is listed for indoor and outdoor use, including outdoor areas, artificial grass, and puppy pads. The directions say to shake well and spray only on the desired area.
Best for: Puppy owners choosing between several potty surfaces, such as pads indoors and artificial grass or an outdoor spot. Its stated range of uses makes it adaptable to different training setups.
Consider: Multiple applications may be needed. Do not spray it directly on your pet, as directed by the product information.
ChunHee Dog Training Bells

This electronic doorbell is designed to teach dogs to signal when they want to go out. It offers 36 sounds, adjustable volume from 0 to 115 dB, and a chew-resistant design. The listing says batteries are included and specifies more than 1,000 rings.
Best for: Owners teaching a puppy to request an outdoor potty break with a sound instead of barking or scratching. Multiple tones can also be assigned to different signals in a multi-dog home.
Consider: The puppy still needs to learn what pressing the bell means, and the bell communicates a request rather than taking the dog outside automatically.
COOYOO Adjustable Dog Doorbells

COOYOO’s hanging doorbell set has five extra-large bells and an adjustable strap measuring 26.5 to 43 inches. A buckle adjusts the strap, and included double-sided tape offers another way to place the bell on a door or wall.
Best for: Owners who want a straightforward, adjustable bell that a puppy can nudge to request an outdoor trip. The strap range and alternative mounting option allow different placement choices.
Consider: This is a sound-making signal, not an indoor potty surface. Plan to teach the puppy to use it and respond by taking the puppy out.
Buying Guide: How To Choose A Puppy Potty Trainer
Do you need an indoor potty spot or an outdoor signal?
Choose the UPIT tray if your plan includes pee pads indoors and you want a grate between the puppy and the pad. Choose a doorbell if the goal is for the puppy to alert you before going outside. Sprays can help identify a preferred potty location, but they do not provide a surface or a communication signal.
Which spray fits your training surface?
Both sprays are listed for indoor and outdoor use. NaturVet specifically mentions puppy pads and artificial grass, while Nature’s Miracle describes a long-lasting formula of up to 12 hours when used as directed. Follow each product’s directions and apply it only to the intended area.
What matters when choosing a doorbell?
Consider how you want the puppy to activate the signal and where you can place it. ChunHee offers electronic tones and adjustable volume. COOYOO uses hanging bells, with an adjustable strap and an option to attach the bell to a door or wall. Either type requires the owner to teach the puppy how to use the signal.
How should a potty trainer fit into a routine?
Choose one designated potty location and use the selected tray, spray, or signal consistently. Take the puppy to the appropriate spot and respond promptly when the puppy signals. A tray and a bell serve different purposes, so select products based on whether the puppy will toilet indoors or ask to go outdoors.
Frequently Asked Questions
Is a potty tray or a training spray better for a puppy?
A tray provides a physical place to use a pad. A spray is used to encourage the puppy to go at a selected location. Choose based on whether you need a surface or a location cue.
Can potty training sprays be used outdoors?
Yes. Both sprays in this guide are listed for indoor and outdoor training. Use each product according to its directions.
Do puppy doorbells prevent accidents?
Doorbells can teach a puppy to signal for an outdoor trip, but the puppy must learn to use them and someone must respond to the signal.
Can NaturVet spray be applied directly to a puppy?
No. The product information says to spray the desired area only and not to spray directly on the pet.
