If your dog has a talent for finding every muddy puddle, stream, or patch of grass imaginable, and you’d rather keep your car and house clean, then what you need, my friend, is a portable dog washer.
These clever little devices are fully mobile, meaning you can shower your dog anywhere. Perfect after a muddy walk, a romp at the beach, or any adventure that leaves your pup looking like a tiny mud monster.
Think of them as tanks of water with a hose and shower head, powered by air pressure. A few pumps of the handle, and suddenly your hands are free to actually scrub, rinse, and tame that muddy fur.
Designed for on-the-go use, they can be filled and tossed in the car boot, ready to spring into action whenever mud strikes.
On chillier days, you can even fill them with warm water for a cosier pup bath. And they’re not just for dogs, you can use them on bikes, football boots, wellies… anything that needs a quick rinse benefits from one of these nifty washers.
We’ve put the best portable dog washers on the UK market for 2026 through their paces, so you can see which ones actually deliver a mud-free, tail-wagging clean.

So what features should you be looking for when buying a portable dog shower ?
Simple to fill at home before venturing out with solid connectors that fit well, are durable and don't leak.
This will depend entirely on the size of your dog. A 5L washer is ideal for small to medium dogs, but if you have a large breed consider an 8L washer. You don't want to run out of water halfway through !
A long hose is preferable to help clean those hard to reach spots.
Water pressure alone won't remove stubborn mud attached to your dog's coat. Ideally a shower head with a brush attachment will work better especially when washing dog paws.
Look for a silent washer. Especially with anxious dogs, motorised washers simply cause more stress.
Consider whether you want extra accessories such as power brushes, towels, pre-wash spray and even insulated jackets. Let's face it, outdoor dog showers in winter are always preferable with warm water!
Splash & Dash are a new name on the portable dog washer scene, offering two sizes: a 5L and an 8L model. For this review, we put the larger 8L version to the test.
And the big news? After thoroughly testing it, the Splash & Dash has officially knocked the Petacarium off our top spot, and that’s been our number one dog washer for the past couple of years.
First impressions? Very positive. Straight out of the box, it felt sturdy, well built, and like it could handle plenty of muddy adventures.
What’s in the box?
✅ The main tank
✅ A neoprene sleeve designed to keep the water warmer for longer (we’ll be testing that later)
✅ A spiral hose that should coil back up neatly after use
✅ A water sprayer with a push button and built in silicone bristles
✅ A handy sprayer holder
✅ A carry handle for easy transport
After testing several portable dog washers over the years, we’ve got a good idea of which features really matter. The tall “scuba tank” style design makes filling much easier, and the raised pump handle position is a big bonus.
Finally, the spiral hose and sprayer head holder are features we haven’t come across before. It’s a clever touch, making the whole unit much tidier to pack away and store.
Filling the Splash & Dash is straightforward. Push the handle down, secure it and twist, the whole mechanism comes out of the tank, leaving a wide hole to fill with water.
Filling with water pre-dog walk is nice and simple… but it does leave you playing a little game of “Is it full yet?”
There is no handy fill line, so if you get too enthusiastic with the water, it can overflow when you pop the handle back on. You also need to leave a bit of air in the tank to pressurise properly, so it is definitely more of a careful pour than a top it right up job.
Once filled, simply screw the handle back on and you're ready to go. Obviously it is fairly heavy with 8L of water (approx 10kg) but the carry strap is ideal for transporting it to the car or simply to the back door.
Several pumps was all it needed to pressurise and the water flowed out. Like other portable dog washers, the flow won't be as strong as mains water, but it's strong enough to clean a dog.
We liked the on/off toggle on the water sprayer keeping you in control. The water flowed for nearly a minute after half a dozen pumps before needing pressurising again.
We absolutely loved the spiral hose. It stretches out to around 2.5m so more than enough to make rinsing those awkward, hard to reach muddy spots on your dog nice and easy.
In total we had over 9 minutes of flowing water from a pretty full tank which should be plenty to clean a large dog.
The water flow is OK (similar to all the washers we feature here) but significantly weaker than from a hosepipe. On the plus side, it's very gentle on your dog's skin and easy to control.
Freddie didn’t mind the water flowing, but he wasn’t a big fan of the silicone bristles brushing against his legs.
It might just be our pup, but maybe softer, more flexible brush bristles rather than the firm, rubbery silicone ones, would be less harsh on our dog’s legs.
That said, they might not be as effective at dislodging dried on mud, so it’s definitely a trade off.
We also tested how well it retained it's water temperature. For the test, we filled the tank with 60°C and tested the temperature every hour for 3 hours.
Time | Temperature |
Initial | 60°C |
After 1 hour | 56°C |
After 2 hours | 53°C |
After 3 hours | 50°C |
The neoprene sleeve did a brilliant job of keeping the water nice and warm, we were genuinely impressed.
It’s worth mentioning though that during our test, the Splash & Dash was stored in the kitchen, so it wasn’t battling freezing temperatures. If you left it sitting in a cold car boot for hours, the water would definitely cool down a bit faster.
The only minor drawback we noticed was when filling the tank. It’s a little bit of guesswork at first to judge when it’s full enough without overfilling. That said, after a couple of uses, we’re confident you’d quickly get the hang of it and be able to fill it to the right level just by eye.
We’d happily recommend the Splash & Dash to anyone with a medium to large dog. Smaller breeds could probably get away with the slightly cheaper 5L version, but for bigger muddy pups, the 8L is spot on.
Our Verdict
Overall, we came away seriously impressed. If you’ve got a mud magnet of a dog and want a portable washer that comes fully kitted out straight from the box.
The Splash & Dash comes with the longest hose of all the brands we tested, and it makes a real difference. We also loved the spiral hose and the spray head holder, which make the whole unit feel neat, compact, and easy to store away after use.
Reasons to Buy + Insulated jacket included + Long spiral hose + Handy shoulder strap + Keeps water warm with insulated jacket |
Reasons to Avoid - Silicone bristles weren't that soft - No colour options |
Only available on Amazon
Petacarium are a small family run business based on the South coast. Experienced pet owners with a successful dog walking, day-care and boarding business, they designed the Petacarium portable shower to be used anywhere and have multiple uses including washing your dog.
Their colourful range includes two sizes of portable showers the 5L and 8L version. Each one comes with -
✅ an insulating neoprene jacket
✅ a 1.3m hose
✅ a 8-setting shower head
We tested their larger 8L model Petacarium portable shower.
First impressions, it looks like a very professional portable shower (very similar style to the Splash & Dash featured in first place).
With a soft neoprene insulating jacket and a strong handle to pressurise the shower, it's certainly holds enough water for multiple dogs or an exceptionally muddy one.
For us, the unique selling point of the Petacarium shower was it's height. As it's considerably taller than the Mud Daddy (featured next), you can pump the handle to create pressure from a standing position. So much easier on your arms and knees!
The shower head included with the Petacarium 5L and 8L models (shown here in blue), has an adjustable dial so you can alter the stream of water just as you would with a traditional garden sprayer.
However, whilst an adjustable shower head has infinite uses at home and around the garden, we feel that for dog washing in particular, a shower with an integral brush is most useful for dislodging pesky mud from your dog's coat.
Petacarium do sell a Pet Shower Brush with silicone bristles for just this purpose. The shower brush has an on/off switch and is available in three different colours - (shown above in green/white).
Performance wise, the Petacarium shower feels solid and although the volume of water makes the 8L version fairly heavy to carry to the car, they have cleverly included a handy shoulder strap with both the 5L and 8L versions.
We loved this thoughtful addition especially as the strap is fully adjustable. It can be used to secure the upright portable shower to your headrests in the car (see photo). Clever stuff!
One flaw was the hose length. We felt that a longer hose would be useful when showering a larger dog to get to all those tricky to reach areas. The Splash & Dash spiral hose at over 2.5m, certainly outperformed the Petacarium here. Longer 2m hoses are available but at an additional cost.
We really rated the neoprene jacket included in the cost. It worked exceptionally well, keeping our water warm after 4 hours, so should be perfect for some lovely, long winter dog walks.
Our Verdict - We think that Petacarium offers a convenient and affordable solution to those messy dog walks.
Reasons to Buy + Insulated jacket included + Range of colours & designs + Handy shoulder strap + Range of additional accessories |
Reasons to Avoid - Brush is an additional purchase - Shorter hose (1.3m) |

Mud Daddy are probably the best known portable dog shower available in the UK. Their patented design is available in 3 different sizes - 5L, 8L and 12L depending on your needs.
For on-the-go cleaning, the Mud Daddy 5L is a good choice. Its unique petrol can-like design is hand-pressurised, delivering a fairly powerful spray through its soft brush, making it ideal for single-use cleanups after beach trips or muddy walks.
Lightweight and easy to carry, even when full, it offers ultimate convenience.
We found that the brush really helps to remove any mud and it comes with a comfortable grip and a on/off lever so you're in control of the water flow. If fact the brush was the best we've tested.
We love the 2m long hose as you can get into those hard to reach places even if your dog keeps moving whilst you hold their collar.
The water stays warmish, but you could opt to invest in a neoprene sleeve to retain heat for longer in the winter months. It's a shame this isn't included as standard like the Splash & Dash or the Petacarium.
If you have a large dog or maybe several dogs who love getting muddy, the 5L version probably doesn't hold enough water, so we'd suggest investing in a slightly larger 8L Mud Daddy.
There were a couple of flaws or downsides.
The Mud Daddy needs pressurising with the pump several times to keep a steady flow of water. We found this harder to do than the Petacarium featured in top spot, possibly due to the angled position of the pump handle.
We also felt that it could use a hose clip to attach the hose and brush to the body of the unit for easy storage and carrying in a similar way to a the Splash & Dash model.
A rechargeable battery operated brush is available to buy, but in our view it's a very pricey accessory.
Available in four colours.
Reasons to Buy + Integral brush head + Long 2m hose + Range of additional accessories + Largest 12L option |
Reasons to Avoid - Insulated jacket purchase separately - More tricky to pressurise |

Our third and final option, is a bit different. Kurgo are a US brand renowned for their travel and safety products.
Their range includes a simple shower head that turns a regular bottle of water into a dog shower.
Essentially, the 'Mud Dog Travel Shower' head screws onto almost any plastic bottle from a 16oz to a 2 litre bottle, so you can have a shower on the go.
A simple and very affordable option, We bought and tested the Kurgo Dog Shower and whilst it's undoubtedly a handy piece of kit for small cleaning tasks we were a bit underwhelmed.
The shower attachment lasts between 1–2 minutes with a 2 litre bottle, so we'd suggest that it's probably aimed more at a dog paw washer rather than a whole muddy dog shower!
There are some obvious limitations to the Kurgo Dog Shower compared to the Mud Daddy and Petacarium versions.
Undeniably it's incredibly convenient, but it doesn't have the option to pressurise, so you need to squeeze the water bottle to produce a stream of water.
Another downside is that it clearly doesn't carry anywhere near the volume of water that our other three featured dog washers offer.
However, in our opinion it does have one big advantage.
The Kurgo Mud Travel Shower has the flexibility to pack it in your walking bag and clean those mucky paws whenever, and wherever you want.
Reasons to Buy + Great value + Simple design + Clean paws anywhere |
Reasons to Avoid - Small volume of water - No integral brush to dislodge mud - No additional water pressure |

If you're faced with a small clean-up job, take a look at our Best Dog Wipes Review. Incredibly versatile, they are super handy to keep by the back door or in the car for a speedy clean up.
If you’ve got a dog that absolutely loves to roll in the mud, then a portable dog shower is a great investment to save your car and home.
Both the Splash & Dash and the Petacarium models options offer a simple, mobile and innovative solution to washing your dog before letting them in your car or home. We love that a portable dog shower keeps the outside, well, outside where it's meant to be.
Both companies offer a 5L and an 8L option with an insulated jacke as standard to keep the water warm.
In testing, the Splash & Dash just pips the Petacarium on overall design and ease of use.
If on the other hand, you're looking for a cheap and simple solution to muddy paws, then the Kurgo Mud Travel Shower maybe just what you're looking for.
If you like to travel with your dog in the car boot after a muddy dog walk then some form of boot protection is a great investment.
Aside from the inevitable mud, dog hair and of course all the general dog walking gear, there's those nasty little scratches which can ultimately prove costly if they impact the resale value of your car.
We've tested a lot of boot liners over the years and the new Ultimate Cargo Liner from Kong is an absolute gem. The designers have considered all the problems dog lovers have and their innovative boot liner delivers all the solutions.
