The number on the scales is only one part of choosing a pet stroller. Two dogs can weigh the same and need quite different amounts of room: one may be long through the body, while the other sits tall or likes to stretch out.
Start with the dog who will actually be riding. A few measurements taken at home will tell you more than a breed label, and make the comparison between models much easier.
Measure the way they like to rest
Wait until your dog is relaxed on a level surface. Measure the space they occupy lying in a natural resting position, recording the length and the widest point. Then note their height when sitting comfortably. Keep the tape beside them rather than pulling them into a pose.
Take a photo of their usual resting position to send with your measurements if you need help. A curled-up dog can look very compact, but that does not mean they will want to stay curled up throughout an outing. Leave room for them to change position and settle.
Compare the cabin, not the outside frame
Open stroller dimensions describe the space the whole pram takes up. Carrier dimensions describe a different part of the product. Use the Uppapets comparison page to check both, and ask our team to clarify usable enclosed space if your dog is close to a measurement.
Hybrid’s listed carrier dimensions are 61 × 34 × 24 cm, while Flander’s are 52 × 34 × 24 cm. Both have a listed width of 34 cm, but the length differs. Do not assume a listed carrier height tells you the full clearance beneath a closed canopy; confirm that detail before ordering for a tall dog.

Check the weight limit separately
A comfortable-looking cabin does not override the maximum pet weight. Hybrid is rated for up to 22 kg, Nero Plus up to 20 kg and Flander up to 15 kg. When pets share, compare their combined weight with the model’s limit, then check that each has enough space.
A puppy also needs a forward-looking fit check. Ask your vet about expected adult size rather than choosing only around today’s weight. Recheck fit as they grow, including how comfortably they can turn and rest with the cabin secured.
Try a simple floor-space check
Mark the published length and width on the floor with removable tape, without asking your dog to squeeze into the outline. Seeing their normal resting shape beside it can rule out an obviously cramped option. It is a useful first check, rather than a substitute for confirming the complete cabin shape and height.
Finally, measure your doorway, storage spot and car boot. The right ride needs to work for both of you. If any measurement is close, contact Uppapets with your notes before choosing; a little checking now makes the first outing easier.
