Summer dog shaving: 16.6x higher risk — UK vets warn: 6 breeds you should never shave (Golden Retriever owners especially)

When temperatures hit 30°C, shaving your dog's coat might seem like the kindest thing to do. But for many breeds, it's exactly the opposite.

July 2026. Temperatures across the UK are climbing. The Met Office has already issued heat health warnings for large parts of England. And every summer, thousands of owners reach for the clippers — convinced they're helping their dog stay cool.

Vets say this is one of the biggest mistakes they see.

Amber Batteiger, a veterinary technician with pet-sitting platform TrustedHousesitters, puts it plainly: "One of the biggest mistakes is shaving double-coated dogs. While it seems logical to remove fur to cool them down, their undercoat acts as insulation against both heat and sunburn. Shaving can disrupt this natural protection, increase the risk of sunburn, and even lead to improper regrowth or skin issues."

How a dog's coat actually works

Here's what many owners misunderstand.

Unlike humans, dogs don't sweat through their skin to cool down. Their primary cooling mechanism is panting. Their coat serves a different purpose.

Double-coated breeds — Golden Retrievers, Huskies, German Shepherds, Samoyeds, Pomeranians, Chow Chows — have two layers of fur:

1、Undercoat: short, hollow hairs that trap air, providing insulation against both cold and heat

2、Topcoat: longer, coarser guard hairs that protect against water, dirt, and UV rays

According to Childs Hill Vets in London, "their coats are designed to provide natural insulation, trapping cool air to keep their temperature from rising and protecting their skin."

When you shave that coat, you remove the very thing that helps them regulate their temperature.

Golden Retriever owners, pay special attention: why your dog is more at risk than others

Golden Retrievers are a classic double-coated breed. Their undercoat insulates against heat and cold. Their topcoat protects against water, UV rays, and physical abrasion.

When you shave a Golden Retriever, three things happen:

First, temperature regulation fails. A Golden's undercoat naturally sheds some in summer, leaving the topcoat to help with airflow and sun reflection. Shave it off, and sunlight hits the skin directly — making the dog more vulnerable to heatstroke, not less. Dr Brian Collins from Cornell Riney Canine Health Center notes: "Shaving a double-coated dog can damage the hair follicles and lead to poor regrowth."

Second, the coat may be permanently damaged. After shaving, the undercoat grows back quickly, but the topcoat grows slowly. The two layers can become mixed, resulting in a coarse, "Velcro-like" texture that attracts grass seeds, twigs, and debris — and is much harder to brush. In some cases, the topcoat never fully grows back, leaving patchy bald spots.

Third, the skin loses its natural protection. The topcoat is a Golden Retriever's first line of defence against UV rays, insect bites, and scrapes. Shave it off, and the skin is left exposed — increasing the risk of sunburn and skin cancer.

Bottom line: for other breeds, a shave might just make them look odd. For a Golden Retriever, it can cause real problems.

Why shaving can make things worse

It increases the risk of heatstroke

This is the counterintuitive reality. Shaving a double-coated dog removes their natural heat barrier. The coat traps cool air against the skin. Without it, the dog loses that insulation and is more vulnerable to overheating, not less.

Vet Dr Karlien Heyrman, head of pets at Pets at Home, warns that "robbing your pet of their natural cooling system can actually lead to overheating, discomfort and sunburn."

It exposes skin to sunburn and skin cancer

A dog's coat protects against UV rays. Shaved skin — especially on light-coloured or thin-coated areas — can burn. Dogs can get skin cancer, just like humans. The nose, ears, and belly are particularly vulnerable.

It can permanently damage the coat

In some breeds, shaving can cause "clipper alopecia" — the fur grows back patchy, or in extreme cases, stops growing altogether. The new coat may be coarser, lighter, or have a different texture.

6 breeds you should never shave

Here are the double-coated breeds vets repeatedly warn against shaving:

1、Golden Retriever — the topcoat may never grow back properly; heatstroke risk increases significantly

2、Husky and Alaskan Malamute — the undercoat is the core insulating layer; shaving disables the entire cooling system

3、German Shepherd — a classic double coat; shaving destroys natural temperature regulation

4、Samoyed — white fur reflects sunlight; shaving removes this natural UV shield

5、Pomeranian — dense undercoat; shaving often leads to "clipper alopecia"

6、Chow Chow — already at 16.6x higher risk of heat-related illness than Labradors; shaving only makes it worse

If you own one of these breeds, please do not reach for the clippers this summer.

What vets actually recommend

Regular brushing, not shaving

"Help your dog to stay as cool as possible by brushing them regularly each week to get rid of excess shed hair," Dr Heyrman advises.

Brushing removes dead undercoat, improves air circulation, and prevents matting — which traps heat against the skin.

Professional trims (not shaves)

For breeds that need it, a professional groomer can give a "summer trim" — shortening the hair without removing the protective undercoat. A groomer can also trim paw pads to help with cooling and prevent matting.

Cooling alternatives that actually work

Childs Hill Vets and Ambleside Vets recommend:

1、Fresh water always available

2、Shade and airflow: keep pets out of direct sun, ventilate their environment

3、Cool resting areas: tiles, damp towels, or cooling mats

4、Walk early morning or late evening — avoid the heat of the day

5、Consider cooling vests or gel-filled cooling mats

When shaving might be necessary

There are a few exceptions. Vets may recommend shaving for:

1、Severe matting that can't be safely brushed out

2、Medical reasons (e.g., surgery or skin conditions)

3、Elderly or overweight pets that struggle to groom themselves properly

In these cases, the vet or groomer will decide what's needed — not the owner's guess about what "looks cooler."

A legal note: UK law requires reasonable steps

Under the Animal Welfare Act 2006, anyone responsible for a dog is legally required to take reasonable steps to protect it from pain, suffering, and disease.

Shaving a double-coated dog in a way that increases its risk of heatstroke could — in extreme cases — be considered a failure to meet that duty. The LAGECDogs legal analysis specifically states that owners of thick-coated breeds are legally required to take extra steps to protect their dogs in hot weather, including careful limits on exercise and more frequent cooling.

1、A Chow Chow is 16.6 times more likely to suffer from heat-related illness than a Labrador.

2、An English Bulldog is 14 times more likely.

3、A French Bulldog is 6.5 times more likely.

If you own one of these breeds, what you do — or don't do — in hot weather matters legally, not just practically.

The bottom line

Every summer, well-meaning owners take their double-coated dogs to the groomer for a "cooling shave." And every summer, vets see the consequences.

If you're wondering whether to shave your dog this summer, here's what vets across the UK want you to know: for double-coated breeds, the answer is almost always no.

Instead of reaching for the clippers, reach for a brush. Book a professional trim if needed. Walk your dog when it's cool. And if you're not sure what's best for your breed, ask your vet.

Your dog's coat isn't just fur. It's a natural cooling system. And it works — if you let it.
