Measure your dog's chest at its widest point, and their back from collar to tail. Frenchies and other deep-chested breeds usually need to size up. If you're between sizes, size up. Put the chest measurement in the box on the product page when you order, and we'll double-check the fit before anything ships. The rain slicker runs S, M and L, and the calming vest runs XS to XXXL.

It's water-resistant, not fully waterproof. The acrylic shell sheds everyday drizzle and mist and helps block the wind, and the full-body cut with sleeves on all four legs keeps more of the wet off the belly and legs. It's rain gear for walks rather than a dry suit, so it isn't made for swimming or hours in a downpour. In freezing weather, layer something warm underneath.

No. The hood is clear, so your dog keeps full view of the sidewalk, the squirrels, and you. Reflective stripes on the body handle the other half of the problem: it gets dark here at four in the afternoon.

It's cut for short backs and broad chests, so Frenchies, Bostons, pugs and bulldogs wear it best. The rain slicker comes in S, M and L, and the calming vest runs XS to XXXL, so plenty of other dogs fit too. Measure the chest and back first and go from there.

Many dogs find gentle, steady pressure soothing during storms, fireworks and car rides, but every dog is different. Put it on at home for short stretches first, on a calm day, and see how your dog settles before the big night. Tito wears his on stormy nights. If your dog's anxiety is severe, it's worth talking to your vet too.
