A bike trailer lets you bring your dog on rides that are too long, too fast or too hot for it to run alongside you. It is also a great way to include senior dogs, small dogs and dogs recovering from an injury, with your vet’s okay. The best dog bike trailers are stable, sized for your dog’s weight, easy to load, well ventilated and safely attached to your bike. Below we compare four popular trailers on Amazon and explain how to get your dog comfortable riding.
Best Dog Bike Trailers Compared
| Trailer | Weight Capacity | Standout Feature | Best For |
|---|---|---|---|
| Schwinn Rascal (Small) | Up to about 50 lb | Light, folding frame | Best overall, small and medium dogs |
| Schwinn Rascal Plus | Up to about 100 lb | Larger cabin, rear doggy door | Large dogs |
| Aosom Elite II | Check listing | Suspension, converts to stroller | Bumpy paths and walking too |
| Aosom Folding Trailer, 20-in Wheels | Check listing | Large wheels, three entrances | Off-road and travel |
1. Schwinn Rascal Bike Pet Trailer (Small) — Best Overall
The Schwinn Rascal is one of the most popular pet trailers on Amazon. The small version is rated for dogs up to about 50 pounds, has a lightweight folding frame, a universal coupler that fits most bikes, mesh windows for airflow and an internal leash to keep your dog safely inside. It folds down for storage in a garage or car trunk.
- Well-known brand with many owner reviews
- Universal coupler fits most bikes
- Folds for storage
- Internal leash and mesh windows
Worth knowing: Check your dog’s height as well as weight; tall, lanky dogs may need the larger model.
2. Schwinn Rascal Plus Pet Trailer — Best for Large Dogs
For bigger dogs, the Rascal Plus is rated up to about 100 pounds and has a roomier cabin, a rear doggy door for easier loading, quick-release wheels, a washable liner and a bug screen. Pulling a large dog is hard work, so it is best on flatter routes or with an e-bike.
- Rated for dogs up to about 100 lb
- Rear door for easy loading
- Washable, non-slip liner
- Quick-release wheels
Worth knowing: A heavy dog plus trailer changes how your bike brakes and handles; ride slowly until you are used to it.
3. Aosom Elite II Pet Bike Trailer and Stroller — Best 2-in-1
Aosom’s Elite II adds suspension for a smoother ride on bumpy paths, and it converts into a stroller or jogger so you can keep using it once you are off the bike. That makes it a good fit for senior dogs and dogs with mobility issues who enjoy getting out but cannot walk far.
- Suspension for a smoother ride
- Converts to a stroller or jogger
- Good for senior dogs
- Mesh windows for airflow
Worth knowing: Check the weight limit and interior size in the listing against your dog before buying.
4. Aosom Folding Dog Bike Trailer with 20-Inch Wheels — Best for Rough Paths
This Aosom trailer has large 20-inch rubber wheels that roll more smoothly over gravel and grass, three entrances for easy loading, mesh screens and a folding frame. It is a practical choice for trail rides, camping trips and anyone who rides on mixed surfaces.
- Large 20-inch wheels
- Three entrances
- Folds for travel
- Mesh screens for ventilation
Worth knowing: Larger wheels make it bulkier to store.
How We Chose These Trailers
We looked at popular trailers with many reviews on Amazon and compared weight capacity, stability, hitch design, ventilation, ease of loading, storage and extra features such as suspension and stroller conversion. We do not list prices because they change; use the buttons to see current prices and reviews.
How to Choose a Dog Bike Trailer
- Weight capacity: choose a trailer rated comfortably above your dog’s weight.
- Interior size: your dog should be able to sit, lie down and turn around without hunching.
- Hitch: most trailers attach at the rear axle; check the coupler fits your bike, especially if you have thru-axles or an e-bike.
- Entry: a rear door makes loading much easier for big or older dogs.
- Safety features: an internal leash tether, reflectors, a safety flag and a secondary safety strap to the bike.
- Ventilation and shade: mesh windows and a covered top protect from sun and bugs.
- Storage: a folding frame and quick-release wheels help if space is tight.
Trailer vs Running Alongside
| Situation | Better Choice |
|---|---|
| Small, senior or recovering dogs | Trailer |
| Hot weather or long distances | Trailer |
| Fit, adult high-energy dog on short, cool rides | Running with a bike attachment, if your vet agrees |
| Puppies with developing joints | Trailer; avoid forced running |
| Busy roads | Trailer, or leave your dog at home |
How to Train Your Dog to Ride in a Trailer
- Set the trailer up indoors or in the yard with the door open, add a familiar blanket and toss treats inside.
- Feed meals in the trailer and let your dog hop in and out freely.
- Clip the internal tether to a harness, never a collar, and close the door for short periods with treats.
- Push or pull the trailer by hand slowly around the yard.
- Attach it to your bike and ride very slowly on a quiet path for a few minutes, then build up.
- Stop often for water and potty breaks, and keep rides short at first.
Use a well-fitted harness from our no-pull harness guide with the tether, and pack a dog water bottle for breaks.
Care and Maintenance
Check tire pressure, wheel quick-releases and the hitch before every ride. Wash the liner and wipe down fabric after muddy trips, and let everything dry before folding to prevent mildew. Store the trailer out of direct sun when not in use, as UV light weakens fabric over time.
Our Verdict
The Schwinn Rascal is the best dog bike trailer for small and medium dogs, and the Rascal Plus is the pick for large dogs. Choose the Aosom Elite II if you want suspension and a stroller conversion, and the Aosom trailer with 20-inch wheels for gravel and trail riding.

Frequently Asked Questions
Are dog bike trailers safe?
Yes, when the trailer is sized for your dog, properly attached, your dog is tethered by a harness, and you ride slowly and cautiously, especially at first.
What size bike trailer does my dog need?
Choose one rated above your dog’s weight with enough room to sit, lie down and turn around. Measure your dog’s height sitting up.
Can any bike pull a dog trailer?
Most bikes can with a universal coupler, but check fit for thru-axles and e-bikes, and make sure your brakes are in good condition.
How do I get my dog used to a bike trailer?
Introduce it at home with treats and meals, then practice short, slow pushes by hand before riding with it attached.
Should my dog wear a harness in the trailer?
Yes. Clip the internal tether to a harness, not a collar, so a sudden stop does not jolt your dog’s neck.
