DoggyRide
A 30 lb aluminum-frame trailer with a 110 lb published limit, a 31.5 x 21 x 25.5 inch cabin, 20 inch pneumatic tires, an interior safety leash, quick-release wheels, and three hitch choices. The center-tow Britch rack connection is the brand's e-bike-compatible, tip-resistant option. Capacity and fit data are unusually clear, but the stroller kit is optional and the current official page has no customer-review aggregate.


Burley
A premium 2-in-1 trailer and stroller with a full internal aluminum roll cage, low center of gravity, integrated parking brake, removable floor, roll-up panels, low rear entry, and included one-wheel stroller kit. Standard supports 75 lb and XL 100 lb. It offers the most complete dog-specific design, but it is expensive, wide, and heavier than bike-only options.

Burley
A 21 lb bike-only trailer with a 75 lb capacity, aluminum frame, 16-inch wheels, mesh windows, low rear tailgate, removable floor, compact fold, storage pocket, and flex connector that lets the bicycle lie down while the trailer stays upright. It is easier to tow and store than conversion models, but stroller mode and an integrated parking brake are absent.

Schwinn
A widely available 50 lb trailer with a folding frame, quick-release 16 inch air-filled wheels, adjustable internal leash, universal coupler, washable nonslip liner, rear dog door, bug screen, and safety flag. It gives the expansion its strongest mainstream review evidence and a moderate purchase price, but it is bike-only, publishes only overall dimensions rather than cabin dimensions, and lacks suspension or a parking brake.

Retrospec
An affordable folding steel trailer with a 50 lb limit, 30 x 19 x 17-inch interior, rear dog door, internal leash, anti-slip floor, 16-inch air-filled tires, weather-resistant 500D shell, canopy/mesh layers, and rear storage. It delivers strong value and a good official review signal, but it is not recommended for thru-axles and visible owner feedback reinforces the need for slow corners and mesh inspection.

Booyah Strollers
A 3-in-1 trailer, stroller, and jogger for dogs around 40 lb or less. It includes the front wheel and adjustable handlebar, plus suspension, a handlebar brake that assists slowing and doubles as a parking brake, and pneumatic tires. Its 26 x 18 x 18 inch cabin and positive official review distribution are useful, but a 34 lb trailer weight is high for the published pet size and buyers must measure doors and pet fit carefully.
