Trailer Comparison Tool
Copy the specifications from the listings of up to three trailers you are considering. The tool checks each one against your dog's measurements and your bike, and flags anything that needs a closer look.
Fit checks use simple rules of thumb (about 4 in of spare length and 3 in of headroom). They flag likely problems; they cannot confirm that a trailer fits or is safe. Verify every figure on the manufacturer's page before buying.
