Once the temperature drops, the dogs that suffer are the ones you would expect: whippets, greyhounds, dachshunds, chihuahuas and almost anything small, thin-coated or elderly. A jumper is the cheapest comfort upgrade you can buy - but only if it fits. The wrong one rides up the back, rubs under the front legs, or becomes a chew toy within a week. Here is how to pick one that actually gets worn.
What to look for in dog jumpers
- Measure girth, not just length: the chest measurement around the widest point, just behind the front legs, decides whether a jumper fits.
- Think about where they toilet: for male dogs a jumper that finishes high on the belly is far easier to live with than a full-body knit.
- Fit by breed shape: dachshunds and greyhounds need long, narrow cuts; stocky breeds need a deeper chest and a shorter back.
- Leg holes that do not chafe: the trim around the front leg openings should be soft and not cut in when they move.
- Machine-washable wool blends beat pure wool: pure wool shrinks and felts, and a dog jumper gets washed often.
- Layering: a thin fleece under a knit adds a surprising amount of warmth for a small dog on a very cold day.
Rough guide: a fleece jumper is the warmest per pound indoors and on short walks; a knitted turtleneck is better under a coat because it is less bulky at the neck.
The best dog jumpers of 2026
Best for long dogs: 2-Pack Knitted Turtleneck Dog Jumpers
~£12-£20
A two-pack of knitted turtleneck jumpers cut long and slim, which is exactly what dachshunds, whippets and other long-backed, narrow-chested breeds need. The turtleneck adds warmth at the throat, and getting two for the price of one means you always have a clean one ready. Supplied in pink and grey in the set shown.
Best for small dogs: Soft Knit Dog Sweater, Small
~£8-£14
A simple soft knit sweater in small sizes, designed for small dogs and cats. The appeal is the low price and the trim fit that suits tiny breeds without dragging on the ground. If you have a chihuahua, a puppy or a cat that feels the cold, this is an inexpensive way to find out what they will tolerate before you spend more.
Best for big dogs: Fleece-Lined Dog Jumper, 5XL
~£15-£25
A fleece-lined dog sweatshirt that goes right up to 5XL, which is rare - most jumpers stop at medium. The fleece inside traps warmth and the design is deliberately easy to take on and off, which matters when you are dressing a large dog twice a day. Available in nine sizes with a bright colourway so you can spot them in the park.
How to get a jumper on without a fight
- Start indoors. Put it on for five minutes, treat, take it off. Build up to wearing it around the house before you ever use it on a walk.
- Go over the head first, then one leg at a time. Trying to thread both legs at once is where most owners give up.
- Check the armpits after a walk. Redness or matted fur under the front legs means the jumper is too tight or the trim is too coarse.
- Wash knits on a wool cycle and dry flat. A tumble dryer will turn a medium jumper into a small one.
- Keep two in rotation. A wet or muddy jumper should not stop the walk.

Bottom line
For long, slim breeds the 2-pack knitted turtleneck jumpers are the best value going, especially at two per pack. Tiny dogs and cats can start with the soft knit sweater for under fifteen pounds, and if you need a size most shops do not stock, the fleece-lined 5XL jumper is one of the few options that will actually fit.
