How to Choose the Right Dog Jumpers

A brisk UK winter can push the air down to 2 °C on average in January. When the mercury dips that low, a dog’s core body temperature can fall fast—especially in short-haired hounds, seniors or pups with joint issues. The right dog jumper acts like a light duvet: it traps insulating air around the shoulders, chest and legs while letting the skin breathe. This guide shows you how to pick a jumper that is warm, comfy and planet-kind.

Do Dogs Really Need Jumpers?

• Thin coats & tiny frames — Whippets, Dachshunds, Chihuahuas and most toy breeds lose heat fast.

• Senior or arthritic joints stiffen in cold, so extra insulation eases pain.

• Low body-fat working breeds (e.g., sighthounds) benefit on frosty dawn walks.

• UK vets advise “putting a dog coat on old dogs or those with thin fur to keep them warm.”

• Legally, UK owners have a duty of care to protect pets from pain, suffering and cold under Section 9 of the Animal Welfare Act 2006.

UK Dog Welfare in the Winters

Cold snaps aren’t just uncomfortable—they can be dangerous. Veterinary data show hypothermia risk rises once outdoor temps stay below 5 °C for an hour. The RSPCA advises keeping kennels or living spaces above 10 °C to prevent chill. That’s a tall order on damp, wet UK mornings when icy rain drives heat away faster than dry cold.

Under the Animal Welfare Act, failing to protect a pet from “unnecessary suffering” can lead to fines or prosecution. The British Veterinary Association adds that older dogs and breeds with thin coats (Whippets, Greyhounds) lose heat quickly through their long legs and slim torsos. A properly fitted jumper or dog coat keeps the chest, belly and joints warm, helping to stave off arthritis flare-ups.

How to Choose the Right Dog Jumper

Choosing the best dog jumper (or waterproof dog coat) is mainly about matching fabric tech to Britain’s damp, chilly conditions and your pup’s daily routine. Use the checklist below to shortlist the right material, then zero-in on color and size.

1. Measure Size

• Back length – Have your dog stand tall with head up so the spine is straight. Measure from the base of the collar to where the tail begins.

• Chest girth – wrap the tape around the widest part of the rib-cage, just behind the front legs. Slide two fingers under the tape; that allowance ensures stretch and easy breathing.

• Neck circumference – measure around the collar line. If you plan to use a deep-collar style, leave a thumb’s width for comfort.

• Movement check – the jumper should hug the core but leave shoulders, elbows and legs free. Dogs that wear a harness will need a jumper with a harness-hole or low chest seam.

2. Choose Material

• Wool sweater: Excellent moisture wicking properties, lightweight, easy to wash, quick drying, and naturally warm. Great for cold, dry weather, but dogs with sensitive skin may find it itchy, so a liner is recommended. Let your furry friend stays warm even after a splashy park run.

• Waterproof jacket: Coated nylon or polyester shell blocks driven rain; anything above 3 000 mm is classed as waterproof for typical UK drizzle, while 10 000 mm resists sustained downpours. Lightweight and convenient, with a waterproof layer to keep your pet dry on wet country walks.

3. Choose Color

Choose a striking red, blue, green, brown, grey or classic navy to keep an eye on your dog and easy for drivers to spot in low light.

Choose the Right Kit For Dog Breeds

Urban commutes & city breaks

French Bulldogs, Pugs and other “tube-shaped” city dogs spend as much time waiting at zebra crossings as they do trotting, so they chill quickly when the wind whips round corners. A lightweight fleece dog jumper in high-vis red or blue, keeps the chest warm and the fabric dries fast if a taxi splashes a puddle.

Country hikes & mud-lovers

Spaniels, Collies and Labradors race through brambles and rivers, so they need protection from both cold and thorns. A waterproof soft-shell dog coat with a zip-in belly panel, fleece lining and harness slot keeps them dry and warm on 10-kilometre trails.

Speedy sighthounds & skinny breeds

Whippets, Greyhounds and Italian Greyhounds have low body fat and lose heat faster than stockier dogs. A long-neck roll-top jumper in insulating wool-mix knit (try classic grey or navy) creates a turtleneck seal that traps heat from ears to tail while still letting these hounds hit 35 mph.

Senior snoozers & arthritic joints

Older Spaniels, Shepherds and giant breeds often stiffen up before dawn. A zip-front thermal fleece jumper with a deep collar allows owners to slide the garment over sensitive hips without forcing any bends, keeping ageing joints supple during frosty toilet trips.

Toy breeds & rain-dodgers

Chihuahuas, Yorkies and Maltese weigh barely 3 kg, so wind chill bites hard. A water-resistant quilted jumper in bright red or cheerful blue, cut with short sleeves and a protective belly flap, prevents puddle splash and keeps these small dogs visible on foggy mornings.

Snow days & mountain trips

Border Collies and adventure mixes that tackle Cairngorm snowfields face –5 °C wind-chill and driving sleet. Layer a thin wool jumper under a triple-layer soft-shell jacket; the breathable membrane vents sweat on the ascent while the outer shell shrugs off ice crystals. Reflective green shoulder panels satisfy The Kennel Club’s call for enhanced visibility on remote, low-light paths, reducing the risk of road-side accidents at trailheads.

Care, Wash and Store

1. Pre-wash prep

• Shake off mud and loose fur, zip or Velcro everything shut, then turn the jumper inside-out. This protects knits, zips and bright colours.

2. Select the right cycle

• Slip the garment into a mesh laundry bag and run a delicate/wool programme at 30 – 40 °C.

• Use a spoonful of fragrance-free detergent and skip fabric softener, which clogs fleece fibres and kills stretch.

• Keep the drum no more than one-third full; less friction extends the life of the knit.

3. Trap micro-fibres

• Fit a micro-fibre filter or use a catching bag: DEFRA-backed studies show filters can stop thousands of plastic fibres escaping into UK rivers each wash.

4. Hand-wash delicate styles

• For cable-knits or embellished jumpers, soak in lukewarm water (≈ 30 °C) with wool-safe detergent for five minutes. Swish gently, rinse clear and press—don’t wring—the water out.

5. Dry the smart way

• Lay flat on a rack, reshape collars and sleeves, and air-dry away from radiators. Hanging wet knitwear stretches shoulders.

• Waterproof dog coats can hang inside-out; avoid tumble dryers, which can crack the membrane.

6. Re-proof & repair

• After every 3–4 washes, re-apply a wash-in or spray-on durable water-repellent so your pup stays dry in British drizzle.

• Spot-stitch small holes early—preventing rips keeps your stock of jumpers rotation-ready.

7. Store for next season

• Wait until the garment is bone-dry, then fold (don’t hang) and place it in a breathable cotton bag with a cedar block to deter moths.

Follow this checklist and your dog jumpers, coats and sweaters will stay warm, comfortable and showroom-fresh for many winters to come.

FAQs

Is it OK for dogs to wear jumpers?

Yes—when the fit is right. A jumper that hugs the chest yet lets the legs move freely helps thin-coated hounds keep their core body temperature stable on cold, wet days. Always remove damp clothing indoors so the skin can breathe, and check for rubbing at the collar and under-arm joints.

Do vets recommend dog coats?

The British Veterinary Association advises owners to “consider putting a dog coat on old dogs or those with thin fur” during frosty spells. Their winter warning adds that coats and jumpers protect senior or under-weight pups from chills and arthritis flare-ups. Choose breathable, insulating fabrics and pair with a harness opening so leads clip on safely.
