Not sure which size?

Between sizes or at the top of a range? Size up. Top-of-range is the worst-fitting spot for any life vest.

Looking for the Bath Hammock? It's one size fits all.

The Pet Bath Hammock has no sizes. Its 8 limb pocket holes let you place each leg where it lands, so the same hammock fits everything from a 4 lb kitten to a 70 lb retriever — nothing to measure.
