Best Dog Litter Tray
As an Amazon Associate we earn from qualifying purchases.
A dog litter tray with grass or a pee pad lets a dog relieve itself indoors, on a surface it recognises, without a trip outside. The products in this comparison are grass pads with a tray, and their listings state sizes, layers, and materials. This guide compares six of them and explains what each size suits. Each entry below gives the figures its listing states, so you can match a pad to your dog and your floor.
Quick answer
- Large dog, one pad with tray: the 23 x 35 inch pad set, listed as three pieces in one pack, at 7.13 lb.
- Five-layer large pad: the LOOBANI 35 x 23 inch pad, listed with a five-layer potty system and TPU.
- Small dog or small space: the 23 x 17 inch pad with tray, listed at 2.64 lb.
- Two-pack for a large dog: the 34 x 23 inch set of two, listed at 7.83 lb.
Pick the size from the dog, not the package
The most common mistake with a litter tray is buying by the pad size alone. A dog needs room to turn, squat and step off the pad without stepping in the tray’s edge. Measure the dog’s length from nose to tail base, then add the width of its stance. A pad that is only as long as the dog will leave no room to turn. Choose the size where the dog can stand, turn and squat without touching the edge of the tray.
Next, look at the layers. The listings describe three-layer, five-layer, and washable pee pad systems. More layers do not mean the pad is better for every dog. They mean the listing describes more of a system for holding liquid below the grass. Check what the listing says about the underlayer before you decide.

The weights and sizes come directly from the listings. Where a listing gives two different figures for the same product, we report both and do not choose one.
Washable pads and disposable pads
A washable pad can be rinsed and dried, which keeps costs down for a dog that uses the tray daily. The listing for the 35 x 22.6 inch product describes washable pee pads. Check the care label before you wash, because the listings do not give a full cleaning schedule. A disposable pad is simpler to replace, but it adds recurring cost. Decide which you will use before you buy.
Whichever you choose, change the pad or wash it when it smells, shows wear, or no longer dries. Standing liquid can make a tray unpleasant for the dog, and a damp pad can slide on a hard floor.
Placement and the floor
Place the tray away from the dog’s bed and food. Dogs prefer not to soil the area where they eat or sleep. Put the tray on a hard surface that can be cleaned, and keep the edge of the tray flat so that it does not tip. Pads that slide create a trip hazard, so check the base or add a rubber-backed mat under the tray if the product allows it.
If your home has carpet, protect it with a mat under the tray. Liquid that runs over the edge can soak the floor below, and the listings do not describe a waterproof base for every product.
How we chose
We kept grass pads with a tray that the listings describe for indoor dog use. We recorded the size, weight, layers and material each listing states. We did not rank the products by reviews, ratings or sales, because this site does not use those figures. Where a listing gives no weight limit or care instruction, we say so.
What we could not verify
- The listings do not state how long a pad lasts before it must be replaced, or how many washes the washable pad tolerates.
- The listings do not compare odour control or absorbency by test. Layer counts are the seller’s description, not a test result.
- The listings do not show how each product drains liquid or whether it resists a dog that digs at the pad.
Product picks
Grass pad with tray, 23 x 35 inches, 3 count
This pack is listed as large and includes three pieces: a pee pad, a grass patch and a tray. At 7.13 lb, it is heavy enough to stay put on most floors. The 23 by 35 inch footprint suits a large dog that needs room to turn.
Skip if: you have a small dog and a small room, because this set takes a lot of floor space.
Limitation: the listing gives a thickness of 1.81 inches for the pad but does not state a weight limit for the dog.
LOOBANI large grass pad with tray, 35 x 23 inches
This pad is listed with a five-layer potty system and a polyethylene and TPU material. At 6.5 lb, it is a solid choice for a large dog. The five-layer description is the most detailed system in this group.
Skip if: you need a washable pad only, because the listing describes a layered system rather than a washable one.
Limitation: the listing does not state a dog size or weight range.
Grass pad with tray, 23 x 17 inches, small size
This small pad is listed at 23 by 17 inches and 2.64 lb, with a three-layer potty system. It suits a small dog or a corner of a small room. Its lighter weight makes it easier to move.
Skip if: your dog is medium or large, because the pad may be too small to turn on.
Limitation: the listing gives no dog weight range.
Grass pad with tray, 34 x 23 inches, 3-layer system
This pad is listed at 34 by 23 inches and 4.84 lb, with a three-layer potty system. It sits between the large and small sizes in weight and footprint. It suits a medium dog that needs more room than the small pad gives.
Skip if: you want a washable pad, because the listing describes a layered system.
Limitation:
Grass pad with tray, washable pee pads, 35 x 22.6 inches
This product is listed at 35 by 22.6 inches and 6.19 lb, with artificial grass and washable pee pads. It suits an owner who wants to rinse and reuse the pads rather than replace them. The listing describes it for puppy potty training and for indoor use.
Skip if: you do not want to wash pads regularly.
Limitation: the listing does not state a washing method or how many washes the pad tolerates.
Grass pad with tray, 34 x 23 inches, 2-pack
This set has two pads in one pack, listed at 34 by 23 inches and 7.83 lb. Two pads let you swap one out for cleaning while the other stays in place. It suits a home where the dog uses the tray every day.
Skip if: you only need one pad, because the second adds weight and cost.
Limitation: the listing describes the pack but does not state the layers or the dog size.
Setting up the tray the first time
Unpack the tray and let the grass pad air out for a few minutes before use, especially if the packaging smells strongly. Place the tray in the spot you want, then put the pad in it and check that the edges sit flat. Introduce the tray in a room with a door you can close, so you can manage accidents while the dog learns the spot.
Put a small amount of the dog’s own urine or a used pee pad in the tray to help the dog recognise it. Many owners use a treat on the pad after the dog uses it, which connects the spot with a reward. Do this every time the dog uses the tray, and reduce the reward gradually as the habit forms.
Daily care and cleaning
Remove solid waste as soon as you see it. Rinse liquid off the grass with lukewarm water, then let the pad dry before the next use. If the pad smells after rinsing, check the layer underneath, because odour can build up in a lower layer that a rinse does not reach. Replace the pad when the grass shows wear or the underlayer no longer dries.
Wash the tray itself with a mild cleaner, rinse it well, and dry it fully. Leftover cleaner can irritate a dog that sniffs the tray, so rinse until no soap smell remains.
Common problems and what to check
If the dog misses the pad, check the size first. A pad that is too small or a tray edge that is too high makes the dog step off the grass. If the dog uses the floor beside the tray, move the tray to a spot with less foot traffic, or clean the floor thoroughly so the scent does not draw the dog back. If the dog refuses the tray altogether, see a veterinarian to rule out a medical cause, such as a urinary problem, before you change the training.
FAQ
How do I train a dog to use a litter tray?
Place the dog on the tray after meals, after waking, and after play, and reward it when it uses the grass. Keep the tray in one place so the dog learns the spot. Expect accidents while the habit forms, and clean them promptly.
Can I use a tray outdoors?
The listings describe indoor use. Outdoor use depends on weather and on whether the product is built for it. Check the label before placing it outside.
Why does my dog step over the edge?
The tray may be too small, or the edge may be too high for the dog to step onto easily. Choose a larger size or a lower edge.
How often should I replace the pad?
The listings do not state a schedule. Replace or wash the pad when it smells, when liquid soaks through, or when the grass shows wear.
Is a litter tray a substitute for walks?
No. A tray can help with indoor relief, but dogs still need walks for exercise and for the mental stimulation outdoors provides.
Bottom line
Choose by the dog’s length and how much room it needs to turn. For a large dog, the 23 x 35 inch set or the LOOBANI five-layer pad fits. For a small dog or small space, the 23 x 17 inch pad is the simplest choice. Plan the washing or replacement schedule before you buy.
