Full-coverage jumpsuit shields body and legs
Waterproof outer sheds rain rather than soaking
Reflective detailing for low-light walks
Large dogs stay drier and easier to spot on wet-weather walks in the Moss Waterproof Dog Raincoat. Built as a full-coverage jumpsuit, it wraps around the body and legs to shield the dog from rain, mud and cold wind, so walk time does not have to stop the moment the weather turns. The waterproof outer layer sheds rain rather than soaking it in, and a hooded neckline helps keep ears and head dry too.
Reflective detailing runs along the coat, adding visibility for early morning and evening walks when light is low. On brighter days the fabric also offers a barrier against strong sun, which makes the Moss useful well beyond the rainy season. Designed for medium and large breeds, it is available in seven sizes from M to 5XL.
Because it covers the legs as well as the back, there is far less mud to towel off at the door and a much drier dog on the sofa afterwards. From The Fernby, it is an easy way to keep a large dog comfortable, dry and easier to see on any walk. Measure carefully before ordering, never leave the coat on an unattended dog, and always supervise pets during use, checking seams and fastenings regularly for wear.

Dry through the whole walk
The waterproof outer sheds rain rather than soaking it in, and the hooded neckline helps keep ears and head dry. Wet weather no longer has to end the walk early.

Less mud at the door
Because the legs are covered as well as the back, there is far less to towel off in the porch and a much drier dog on the sofa afterwards.
Comfort that earns its place in the room
The Fernby range is built around how dogs and cats actually live — memory-foam beds, soft brushed blankets and washable covers, chosen to last and made to sit right at home.
Built to last, made to look at home
Every piece is chosen for how it holds up over months, not just day one — washable covers, resilient foams and fabrics made to keep their shape.
Seven sizes run from M to 5XL, covering smaller medium breeds through to giant breeds. Measure the dog and compare against the chart before ordering, sizing up if between sizes.
