Cycling with a Labrador, German Shepherd, or Golden Retriever used to mean leaving them at home. Standard pet carriers simply can't handle dogs weighing 30kg or more, and running alongside a bike isn't safe or practical for most large breeds. That's where dedicated dog bike trailers come in.
A quality dog bike trailer lets you take your large breed on cycling adventures, giving older dogs or those recovering from injury a way to enjoy the outdoors without overexertion. Whether you're commuting along canal towpaths or exploring Kent's woodland trails, the right trailer means your dog comes too.
This guide covers the best dog bike trailers available in the UK for large breeds, including models that handle dogs up to 80kg. We'll look at what actually matters when choosing a trailer, review five top options, and share practical tips for getting your dog comfortable with their new wheels.
Not every dog can run alongside a bike for miles. Age, injury, and certain health conditions mean many large breeds benefit from hitching a ride rather than walking or running the whole distance.
Senior dogs with arthritis or joint problems still want to be outside exploring. A bike trailer gives them that mental stimulation and fresh air without putting stress on ageing joints. Dogs recovering from ACL surgery or other injuries can use trailers to gradually build back fitness while still joining family outings.
Brachycephalic breeds (flat-faced dogs like Bulldogs) struggle with heat and exertion. On warm days, a well-ventilated trailer keeps them cool and safe while you cover ground they couldn't manage on foot. For more on keeping these breeds safe, see our guide to brachycephalic breeds heat management.
Even fit dogs have limits. If you're planning a 20-mile ride through the Kent Downs, your dog probably can't match that pace on foot. A trailer means longer rides become possible. Your dog can walk sections of the route and rest in the trailer when needed.
Commuters use trailers too. Cycling to work with your dog, dropping them at daycare, then picking them up on the way home becomes straightforward with a reliable trailer setup.
Running dogs alongside bikes is risky. They can dart into traffic, trip you up, or injure themselves on uneven ground. A secure trailer keeps your dog contained, visible to other road users (most have reflectors and flag poles), and protected from debris or passing vehicles.
Choosing a trailer for a large dog isn't just about finding the biggest one. Several factors determine whether a trailer will work for your specific dog and riding style.
Here's something manufacturers don't always make clear: maximum weight capacity doesn't tell you if your dog will fit. A trailer rated for 45kg might not have enough floor length for a 35kg Labrador to lie down comfortably. Weight limits indicate structural strength, not interior space.
Measure your dog from collar to rump (their spine length) and compare it with the trailer's interior floor length. Your dog should be able to lie down fully stretched out. For tall breeds like Greyhounds or Setters, check the interior height too—your dog shouldn't have to crouch the entire journey.
A low entry point is critical for older dogs, those with mobility issues, or any large breed that struggles to jump. Some trailers have step-in heights of just 14cm, making access effortless. Others require your dog to leap over a high lip, which is fine for agile youngsters but impractical for arthritic seniors.
Front, rear, or side entry options vary between models. Think about where you'll be loading your dog—if you're often parked in tight spaces, a side-exit trailer might work better than one that only opens at the back.
Don't get fixated on suspension systems. A quality dog bed or thick padding on the trailer floor does more for your dog's comfort than fancy springs. Bumps and vibrations transfer through the wheels regardless of suspension—a well-cushioned lying surface absorbs that far better.
Some trailers come with removable, washable liners. Others have bare floors, expecting you to add your own bedding. Factor this into your budget if the trailer doesn't include padding.
If you're using an e-bike (and many large-dog owners do, since pulling a 40kg dog takes effort), check compatibility carefully. Not every trailer handles the torque and speeds of electric bikes. UK-legal e-bikes are limited to 25km/h (about 15.5mph), but that's still faster than typical cycling speeds with a heavy load.[1]
Compatibility often depends on your bike's axle type. Through-axles, quick-release, and different dropout widths may all need specific adapters. Check what hitch system the trailer uses and whether it matches your bike before ordering.
A trailer carrying a large dog takes serious punishment. Look for aluminium frames (lightweight but strong), reinforced wheel attachments, and sturdy fabric that won't rip when your dog shifts around. Cheap trailers might seem like a bargain until the frame bends or a wheel breaks after a few months.
Wide tyres (18-20 inch) handle heavier loads better and cope with gravel, grass, and woodland paths. Air-filled tyres offer a smoother ride than solid ones but need occasional pumping.
These five trailers are specifically designed for large and heavy dogs, with weight capacities from 45kg to 80kg. Prices and availability reflect the UK market as of late 2024.
The Hercules 2.0 from InnoPet is a versatile 2-in-1 option that works as both a stroller and bike trailer. It supports dogs up to 50kg with cabin dimensions of L78 x W60 x H68cm.[2]
Key features:
The Hercules works well for owners who want both trailer and stroller functionality without buying separate units. Its cabin height (68cm) suits most large breeds, though very tall dogs like Great Danes would feel cramped.
Considerations: InnoPet recommends a maximum speed of 16km/h, which is below the UK e-bike limit. If you ride an e-bike, you'll need to moderate your speed accordingly.
Versatile 2-in-1 bike trailer and stroller for large dogs up to 50kg
German manufacturer Croozer designed the Bruuno specifically for very large and heavy dogs. With a 45kg capacity, it focuses on accessibility and interior height rather than raw weight limits.[3]
Key features:
The Bruuno excels where mobility is limited. That 14cm step-in height is genuinely low—older dogs with hip dysplasia or recovering from surgery can walk straight in without jumping. The tall interior lets dogs sit upright naturally.
Considerations: Premium pricing reflects the quality. Croozer offers extended warranties, which adds confidence for a significant investment.
Premium German-engineered trailer with 14cm low entry for senior dogs
The Bark Ranger XL from American manufacturer Burley handles dogs up to 45kg (100lbs) and is explicitly designed for e-bike compatibility. Interior dimensions are L92 x W57 x H76cm.[4]
Key features:
Burley's reputation for child bike trailers carries over here. The Bark Ranger isn't flashy, but it's well-engineered and straightforward to use. Storage space for treats, leads, and water bowls fits around your dog.
Considerations: The interior is unpadded—you'll need to supply your own dog bed or cushioning. No integrated leash attachment means you'll need a separate tethering solution. For ideas on suitable beds, check our guide to the best orthopaedic dog beds for large breeds.
E-bike compatible trailer with quick folding mechanism for easy storage
For the biggest dogs, the German-made DoggyTourer Beethoven XL stands out with an 80kg weight capacity—enough for giant breeds like Newfoundlands or St Bernards. Dimensions are L131 x W92 x H99cm.[5]
Key features:
DoggyTourer targets serious cyclists with giant breeds. The Weber coupling system is known for reliability and works with most e-bikes. Handmade in Germany, these trailers feel overbuilt in the best possible way.
Considerations: Premium price point reflects the giant-breed market. The size means storage space at home needs consideration. The coupling is sold separately.
Giant breed specialist trailer with 80kg capacity and 25-year warranty
Norwegian brand Hamax brings the Pluto Large to the market with a 45kg capacity. It's praised for balancing features with value, making it a sensible middle-ground option.[6]
Key features:
The Pluto offers a well-rounded package without the premium pricing of Croozer or DoggyTourer. The adjustable suspension is a thoughtful touch—you can dial it in for a lighter Border Collie or stiffen it for a heavier Rottweiler.
Considerations: Optional stroller kit sold separately if you want push functionality. Check compatibility with your specific bike type before purchasing.

Make your dog's trailer more comfortable with a memory foam dog bed cushion or add safety with a secure tether attachment. These accessories improve comfort and safety on longer rides.
Throwing your dog straight into a trailer and cycling off isn't the approach. Most dogs need gradual introduction to feel relaxed in their new ride. The American Kennel Club recommends a step-by-step desensitisation process.[7]
Set up the trailer indoors in a familiar space. Leave it open and let your dog investigate on their own terms. Toss treats inside, feed meals in there, and praise any voluntary exploration. The goal is making the trailer a positive space before it ever moves.
Once your dog happily hops in for treats, practice closing the doors briefly while you sit beside them. Reward calm behaviour. Open the doors, let them exit, and repeat. Build up the time gradually.
With your dog settled inside, rock the trailer gently while staying right beside them. Then try pushing it around the house or garden without the bike attached. Reward calm behaviour throughout. If your dog panics, you've moved too fast—go back a step.
Short sessions beat long ones. Five minutes of positive practice is better than twenty minutes that ends in stress.
Attach the trailer to your bike but don't ride yet. Walk the bike with your dog in the trailer around the garden or a quiet street. Get them used to the noise, the slight swaying, and being behind a moving object.
When that feels comfortable, try a very short ride—just a few metres. Build up distance slowly over several sessions. Most dogs adapt within a few weeks if you don't rush the process.
Cycling with a large dog trailer changes how your bike handles. A few adjustments make the experience safer and more comfortable for everyone.
Stopping distance: Plan to brake earlier than usual. A 40kg dog in a 15kg trailer is 55kg of momentum pushing you forward. Start slowing well before junctions, corners, and obstacles.
Width awareness: Your vehicle is now significantly wider. Check clearance when passing bollards, gates, or parked cars. On shared paths, remember the trailer extends behind you—don't cut in front of pedestrians.
Corners: Take them slower and wider than you would without the trailer. Tight turns at speed can tip a trailer, especially with a dog shifting weight inside.
Dog bike trailers handle best on:
Avoid technical mountain bike trails, deep sand, and very rutted surfaces. The trailer can bounce, tip, or get stuck—none of which your dog will appreciate.
Yes, cycling with a dog trailer is legal in the UK. There's no specific legislation banning it. You must still follow normal road rules and ensure your dog is secured safely. Common sense applies—don't obstruct traffic, use lights in low visibility, and keep to appropriate paths where possible.
Technically possible, but not ideal. Child trailers aren't designed for dogs. They lack proper ventilation for panting animals, don't have internal tethers to secure your dog, and often have floor surfaces that are slippery for paws. Purpose-built dog trailers address these issues.
Measure your dog's spine length (collar to rump) and compare it with the trailer's floor length. Your dog should be able to lie fully stretched out. Also check interior height if you have a tall breed—they shouldn't have to crouch constantly. Weight capacity is about structural strength, not space.
Patience and positive association are your tools. Never force a reluctant dog. Set the trailer up indoors, toss treats inside, feed meals in there, and let your dog explore voluntarily. Most dogs come around within a week or two of gentle encouragement. For help with nervous dogs, see our guide to preparing anxious dogs for new experiences.
A good dog bike trailer opens up cycling for owners of large breeds. Senior dogs regain access to adventures. Recovering dogs can still join family outings. And fit dogs can rest when needed on longer rides.
Focus on getting the size right—your dog's comfort matters more than impressive weight limits. Invest in quality padding if the trailer floor is bare. And take time introducing the trailer properly before expecting your dog to love it.
With the right trailer and a bit of patience, your large breed can be your cycling companion for years to come.
