Dog wheelchair measurements are not universal. First work out whether your dog needs rear, front, quad or adapted amputee support. Then choose the wheelchair system and use that manufacturer's own measuring instructions. The Hub does not sell wheelchairs or receive commission.
A measurement used for one brand may not be what another manufacturer needs. Choose the support type first, compare suitable systems, then measure using the maker's current instructions.
Start with the support your dog needs. These guides explain the differences before you spend money or take measurements.
Ready-made adjustable frames. Height, length and width can be adjusted to the dog.
Custom-made frames that retain adjustment for fitting after delivery.
Individual carts built around the animal's disability, body shape and measurements.
Budget chairs can be useful, but first identify the exact make and model. Do not assume instructions for Walkin' Wheels, K9 Carts or Eddie's Wheels apply to a different chair. Look for the manufacturer's own size chart and fitting instructions before buying.
Measuring gets you to the correct size range; fitting still matters after the chair arrives. Check frame height and length, harness position, support, balance and comfort before building up walking time.
Start with the Dog Wheelchair Finder. Once you know the support type and wheelchair system, return here and use that manufacturer's own method.
