Dog bike trailer weight limits: which size do you need?
The four limits, side by side
From the manufacturer specs of the trailers we sell:
| Trailer | Rated to | Type | Assembled (in) | Trailer weight |
|---|---|---|---|---|
| The Trail Hauler | 66 lb | Bike trailer | 49.2 x 26.8 x 36.2 | 22 lb |
| The Big Wheel Wagon | 88 lb | Bike trailer | 55.5 x 29 x 29.25 | 26.5 lb |
| The Tow & Stroll | 100 lb | Trailer + stroller | 46 x 27 x 44 | 28.4 lb |
| The Big Dog Tow & Stroll | 110 lb | Trailer + stroller | 51 x 27.5 x 39 | 27 lb |
All four use 20 in rear wheels, which roll over gravel, grass and curbs more easily than the 16 in wheels on some budget trailers.
Why buy above your dog's weight
The rating is the most the frame and wheels are built to carry, not a comfortable everyday load. A dog shifts its weight, stands up and lies down while you ride, and anything else in the cabin counts too. If your dog is close to a limit, step up a size.
Check length and height, not just pounds
Measure your dog lying down, nose to the base of the tail, and sitting, floor to the top of the head. The 88 lb trailer has a cabin about 28 in long under a roll-up top panel; long-bodied dogs of the same weight may be happier in a taller 2-in-1 model, where the 100 lb version stands 44 in tall overall. A dog that cannot lie down will keep trying to stand, which makes the ride less steady.
Trailer only, or 2-in-1?
A plain trailer is lighter and folds flat; the 66 lb model weighs 22 lb. A 2-in-1 adds a front caster so you can unhitch at the park and push it as a stroller, which helps with older dogs or dogs recovering from surgery that can ride to the trail but not walk all of it. The 100 lb model folds its tow bar back and rolls on two 8 in swivel casters.
Check the hitch before you order. The Trail Hauler mounts at the rear axle of bikes with 24 in or larger wheels. Start with short rides at walking pace on a quiet path, and clip the inside tether to a harness, not a collar.
Small dogs: a stroller instead
Under about 15 lb, most dogs do not need a bike trailer at all. The Double Decker carries two pets up to 15 lb each on separate levels, and the top basket lifts off as a carrier.
