Let us clear one thing up first. Dogs do not use litter boxes. Nobody is making a cat-style litter tray for a Labrador, and you should be suspicious of anyone who claims otherwise. When large-dog owners search for a “travel litter box,” what they actually need is a portable dog potty: a turf-covered tray or an enclosed pad station that gives a big dog somewhere to go inside a hotel room, an RV, or an apartment balcony when a walk is not an option.
This guide rounds up six portable potty systems that actually come in sizes a large dog can use. A few honest realities before you spend a dollar: none of these replace walks, and an undersized tray is worse than no tray at all, because a dog that misses the target learns the tray is optional. Size, cleaning discipline, and realistic expectations matter more than brand names here.

1. LOOBANI Large Dog Grass Pad with Tray, 35x23in
Thirty-five inches of pad. That is the number that matters most, because most “large” dog potties shrink the moment you look at the fine print. The LOOBANI is the closest thing in this category to a genuine large-breed footprint, and the bundle thinking is practical: two grass patches and two washable pee pads, so you can rotate a dirty set out while the spare is in service. A 2-year warranty on a product like this is unusual enough to mention twice. Turf systems are disposable by nature; LOOBANI is at least standing behind theirs.
Now the unglamorous part. Artificial grass does not stay fresh on its own. Owners who skip the twice-a-week hose-and-soap routine report the exact odor problems you would expect from a plastic lawn sitting in urine, and no amount of drainage-hole engineering fixes neglect. The tray sits only 1.38 inches tall, so a leg-lifting male will overshoot it, and owners of truly giant breeds still call 35×23 tight. This is the best turf-tray value for large dogs, not a magic solution to cleaning.
- Key specs:
- Size: 35.04″ x 22.64″ x 1.38″
- Weight: about 6.5 lbs
- Materials: artificial grass (PE) over a TPU tray
- Includes: 2 grass patches, 2 washable pee pads, 1 tray
- Warranty: 2-year
Pros: widest pad in this roundup; spare grass and pads included for rotation; 2-year warranty; thousands of owner reviews averaging 4.2 stars.
Cons: needs washing about twice a week or it stinks; low tray profile gives no splash protection; giant breeds may still find it small.
Verdict: the safest turf-tray bet for large dogs. If your dog will use artificial grass and you will commit to cleaning it, this is the one to buy. Check Price on Amazon
2. PetSafe Pet Loo Indoor Pet Toilet, Large
The PetSafe Pet Loo is the granddaddy of this category, and the design shows it in both good and bad ways. The 33-by-33-inch square footprint gives a dog room to circle, which matters more than most manufacturers admit. Dogs do not always land where they start. The raised platform keeps everything off your floors, the tray pulls out for dumping, and PetSafe has been making pet products since 1998, so spare parts and support actually exist.
But an older design carries older compromises. The synthetic grass mat has a rubber backing that takes an age to dry after washing, and it slides around under the weight of a heavy dog. Replacement grass pads are expensive for what they are. Perhaps the biggest real-world complaint: the raised platform spooks some dogs, and several owners report their dog refusing to step on it at all for the first days or weeks. A one-hundred-pound dog refusing the platform is not a training problem you can solve from the road. Also, puppies chew the grass mat to pieces. Budget for replacements or skip this one for a young heavy chewer.
- Key specs:
- Size: 33″ x 33″ x 5.5″
- Weight: about 2.2 lbs (per Amazon product info)
- Materials: plastic base with rubber-backed synthetic grass mat
- Includes: Pet Loo unit with grass mat (33 x 33)
- Warranty: 1-year limited
Pros: square 33×33 layout gives circling room; raised design contains mess off floors; removable tray empties easily; long-established brand with real support.
Cons: rubber-backed mat dries slowly and slips under heavy dogs; replacement grass is pricey; raised platform startles some dogs; puppies destroy the mat.
Verdict: the trustworthy brand pick for a big dog that is already comfortable stepping onto things. Confirm your dog will mount a raised platform before relying on this on a trip. Check Price on Amazon
3. HQ4US 4LEGS Foldable Dog Litter Box with High Walls
This is the product I would throw in the back of an SUV. The tub is one seamless piece, so there are no joints for urine to seep through, and it folds flat in seconds, no tools, no clips, no swearing in a hotel parking lot. Three walls stand 16 inches high, which is the feature that separates this from every open turf tray on the list. A male dog that lifts his leg defeats a flat pad every time. Walls do not.
Choose the XL size if your dog is over 60 pounds; the standard large tops out around that range, and an enclosed box that is too small creates the same miss-the-target problem as an open one. Ownership reality check: this thing needs cleaning every couple of days or it develops the unmistakable smell of every neglected dog toilet, and hauling a wet, wobbly tray to the bathtub is the chore several owners complain about loudest. A few owners also flag the plastic tray quality as just okay for the money. And heads up: some dogs decide the grass pad is a comfortable bed, not a bathroom. Introduce it with the dog on a leash if yours is a lounger.
- Key specs:
- Size (Large): 33.2″ x 22.8″ x 16″ (dogs 10-60 lbs); XL fits 60-100 lbs
- Construction: one-piece seamless foldable tub, no assembly
- Walls: three high walls, 16 inches tall
- Includes: 2 grass pads, 4 spring clips
- Folding: bi-fold flat for travel storage
Pros: folds flat for the car; seamless tub cannot leak at joints; high walls handle leg-lifting males; zero assembly.
Cons: needs cleaning every couple of days or odor builds; wet tray is awkward to carry; tray plastic quality divides owners.
Verdict: the best travel-first pick here. Buy the XL for a large dog, and plan your cleaning routine around every other day. Check Price on Amazon
4. HURENTEK Dog Grass Pad with Tray, 34×23
HURENTEK plays the same turf-tray game as LOOBANI with one structural difference worth noting: a middle layer of high-density pearl cotton that is supposed to drain liquid into the tray while keeping paws off wet grass. In practice, the drainage does work, and the system is about five pounds, which is genuinely easy to carry in and out of an RV or a hotel room. The tray edges are raised 2.7 cm to catch spillover.
The tradeoffs are the usual turf-tray ones. The grass and the cotton layer both need regular washing, and a handful of owners find the grass hard to get truly fresh again after a few months of heavy use. It is an open, low-profile tray, so no splash protection. And HURENTEK is a newer brand with a thinner review history than the big names above, which is fine if you are price-shopping but worth knowing. Nothing here is a dealbreaker. Nothing here is special either, except the light weight and the explicit RV and travel positioning.
- Key specs:
- Size: 34″ x 23″
- Weight: 2.27 kg (about 5 lbs)
- Layers: artificial grass mat + 1.5 cm pearl cotton pad + tray
- Tray edges: 2.7 cm raised
- Amazon rating: 4.2 stars from 443 reviews
Pros: light at five pounds; pearl cotton layer drains well; raised tray edges catch spillover; large footprint for the price.
Cons: turf and cotton layers need frequent washing; odor can set into the grass over months; open tray with no splash walls; newer brand.
Verdict: a solid lightweight turf option for RV and car travel. Good for a dog that pees neatly; not for a male that lifts. Check Price on Amazon
5. Shimeyao Stainless Steel Dog Potty, 32×20
Full honesty: this is the least travel-appropriate product on the list, and it earns its spot for exactly one type of owner. If your large dog chews plastic trays to pieces, a steel potty is not a luxury, it is the only category that survives the dog. The mesh top layer keeps paws dry, the sloped base drains urine toward the waste pipe, and the 140-pound load rating is the highest in this roundup. There is a drain hookup and an automatic flush option, which reads like overkill until you have spent a year hosing a plastic tray in January.
The problem is the “travel” part of your search. This weighs seventeen pounds, it is rigid stainless steel, and the plumbing features make sense at home, not in a hotel room. It is also a new listing with a thin owner review history, so the durability story is the manufacturer’s claim, not a track record. Buy this for a chewer at home. Do not buy it expecting to lug it on road trips.
- Key specs:
- Size: 32 x 20 inches (31.5″ x 19.69″ x 6.69″)
- Weight: about 17 lbs
- Material: stainless steel
- Load rating: up to 140 lbs
- Walls: removable high pee walls / splash guard
- Features: sloped base, mesh top layer, drainpipe connection, flush option
Pros: chew-proof and rust-proof; highest weight rating here; mesh top keeps paws clean; drain and flush option for home use.
Cons: far too heavy for real travel; thin review history; premium price for features you cannot use on the road.
Verdict: the right answer for a destructive large dog at home, the wrong answer for a travel potty. Check Price on Amazon
6. OCMML Foldable Dog Litter Box with High Walls, 23.62″
The OCMML is the outlier here: a foldable box made of waterproof Oxford fabric instead of rigid plastic, weighing just over two pounds. For travel, that weight and the fold-flat profile are genuinely appealing. It packs down to almost nothing. The 17.7-inch walls with a low-entry front block splash from all sides while letting a stiff or senior dog walk in without climbing.
Now the caveat that keeps this at number six: 23.6 inches square. For a Labrador-sized dog, that is tight. Measure your dog nose-to-tail and compare, because a large dog that cannot fully turn around on the pad will go half on and half off, which defeats the purpose. The fabric walls also lack the rigidity of a hard tray, so a heavy dog leaning on them can collapse a side. And note the listing includes no grass or pads, so factor in that extra purchase. This is a good travel backup for a medium-large dog, not a primary toilet for a big one.
- Key specs:
- Size: 23.62″ x 23.62″ x 17.72″
- Weight: 2.3 lbs
- Material: waterproof Oxford cloth (nylon)
- Walls: 17.7-inch walls with 1.18-inch front splash guard, low-entry front
- Includes: removable grate, carry handles (grass/pads sold separately)
Pros: lightest option here; folds flat for luggage; tall fabric walls block splash; works with pads or grass.
Cons: too small for many large dogs; soft walls can collapse under a heavy dog; inserts cost extra.
Verdict: the most packable option, but only for a dog that physically fits it. Measure first. Check Price on Amazon
Buying Guide: Choosing a Travel Potty for a Large Dog
Size before everything. A large dog needs at least 30 inches of usable pad in each direction, and room to circle matters as much as raw length. If the product page only shows a small dog in the photos, treat the size claims as marketing and check the dimensions.
Walls beat flat trays for males. A flat turf pad handles a squatting dog fine. A leg-lifting male defeats it every time. If your dog lifts, only consider high-wall boxes: the HQ4US, the Pet Loo, or the OCMML.
Plan the cleaning, not just the purchase. Every turf system on the market smells if neglected. The honest maintenance schedule is a rinse every one to two days and a real soap wash once or twice a week, with a spare grass mat rotating in while one dries. If that sounds like too much, a disposable-pad tray system is a better fit for your life.
Weight and foldability for actual travel. A five-pound tray gets carried. A seventeen-pound steel station does not. If the potty lives in the RV full-time, weight is irrelevant; if it moves between the car and the hotel, fold-flat wins.
Train before the trip. No dog walks up to a turf tray and uses it instinctively. Put the tray where the dog already goes, move a soiled pad onto it once, reward heavily, and give it a full week at home. Discovering on night one of a hotel stay that your dog is terrified of the raised platform is an avoidable disaster.
Materials and durability. Heavy chewers kill plastic trays and turf mats; the stainless option exists for exactly that dog. Fabric walls are light but collapse under leaning weight. Stainless and rigid plastic survive; fabric survives the luggage, not the dog.
Do large dogs actually use travel litter boxes?
Dogs do not use litter the way cats do. What large-dog owners call a “travel litter box” is really a portable dog potty: an artificial grass tray or an enclosed pad station. Most dogs will use one if it is introduced at home first with rewards, but it is a trained behavior, not an instinct. Do not expect a dog to figure it out on night one of a road trip.
What size portable potty does a large dog need?
At least 30 inches of usable surface in each direction, with room to circle. Rectangular trays around 34×23 inches suit most large breeds; square formats like the 33×33 Pet Loo give extra turning room. Boxes under 24 inches square are tight for a true large dog and often cause half-on, half-off misses.
How do you keep a travel dog potty from smelling?
Rinse the grass and tray every one to two days and wash with soap once or twice a week. Keep a spare grass mat so one can dry while the other is in use, because a damp mat is where the smell starts. Enzymatic pet cleaners work far better than dish soap on set-in urine odor.
Can you take a dog grass pad on a plane?
Not realistically as carry-on. Grass trays are bulky, and no airline treats one as a pet relief area in the cabin. They make sense for road trips, RVs, and hotel rooms, where you set one up on a balcony or in a bathroom. For flights, plan around layover pet relief areas instead.
Are artificial grass potty pads safe for dogs?
Generally yes for normal use, but watch for two things: dogs that chew turf can ingest plastic fibers, so supervise chewers and consider a steel or grate-style tray instead; and some turf mats have a chemical smell when new, so wash and air them out before first use.
How often do you replace the grass mat?
With regular washing, a grass mat typically lasts two to six months before the odor stops coming out and the fibers mat down. Heavy daily use by a large dog lands at the short end. Rotation with a spare mat and enzymatic cleaner stretches the life; when a fresh wash still smells, replace it.
