The layered look here is one garment, not two. A navy knit vest is made up with a plaid shirt collar and sleeves built into it, so your dog gets the appearance of a shirt under a jumper without you having to dress them twice or manage two sets of leg holes on a wriggling terrier. For most dogs, one layer going on once is the whole difference between cooperation and a chase round the kitchen.

Underneath the styling it is doing a straightforward job, which is adding an insulating layer for dogs who lose heat quickly. Small breeds have a lot of surface area for their body mass, and short-coated ones have very little insulation of their own, which is why a whippet shivers on the sort of morning a labrador enjoys. Weights run from 166g to 216g, so it stays a light layer rather than a bulky coat.

On sizing and weather. Knit is not waterproof and will hold water once it gets properly wet, so treat this as a dry-day and indoor layer rather than a winter coat. Measure your dog's back length from neck to tail base before choosing a size, because we have no chart from the maker and would rather confirm a fit with you than print numbers we cannot verify.

Who it's for: Small and short-coated dogs who feel the cold on dry days, and owners who like their dog turned out smartly.
