If you’re stuck between L and XL, you’re not alone—most sizing mix-ups happen right in that in-between zone. The easiest way to decide is to focus on three things: your dog’s measurements, their weight range, and how they like to ride (curled up vs. stretched out).
Grab a soft measuring tape and measure:
Length: from the base of the neck (where the collar sits) to the base of the tail.
Chest: the widest part of the ribcage (usually right behind the front legs).
Height (optional but helpful): from floor to the top of the shoulders.
If your dog’s chest or length is close to the top end of the L range, sizing up to XL is often the cozier, safer choice—especially for carriers and travel gear where a cramped fit can cause stress.
Dogs who naturally curl into a donut can often stay comfortably in L, even if they’re near the upper end. Dogs who prefer to sprawl, switch positions, or travel for longer stretches usually do better in XL so they can settle without pressing against seams or zippers.
XL is typically the better pick if any of these are true:
• Your dog is broad-chested (bully breeds, stocky mixes).
• Their weight is near the top of the L range.
• You’ll use the item for car rides, airport days, or extended outings.
• Your dog gets anxious in tight spaces and relaxes with extra room.
For carriers and travel bags, your dog should be able to sit and turn around comfortably, with no pressure on the chest. A little extra space is fine—too tight isn’t.

It can be a good choice for many dogs if it fits their size and sleep style and uses supportive, washable materials. Look for a non-slip base, durable stitching, and enough cushioning—especially for seniors or larger breeds.
