How to Choose the Right Collar, Harness & Lead for Your Dog or Cat

Every dog is different. And nowhere is that more obvious than on a walk.

Bruch — my chocolate dog who passed away a few years ago — was, in many ways, the dream walking companion. Fabulous recall, no pulling, completely reliable off lead. A collar and lead was perfect for him, and walks were a joy from start to finish. I still think about him on every walk.

Then there's Hugo.

Hugo is a rescue French Bulldog cross with the recall of a potato and the pulling power of a small tractor. He was also attacked by another dog, which means open spaces with unknown dogs aren't something we take lightly. Hugo has a retractable lead, and we use designated enclosed areas where he can run freely — safely contained, no risk of him doing his best Houdini impression, and no anxiety about unexpected encounters with other dogs.

Two dogs. Two completely different setups. Both completely right for their dog.

This guide will help you figure out what's right for yours — and yes, we'll be talking about cats too.

If your pet has specific behavioural needs, anxiety, or has been involved in an incident with another animal, we'd always recommend working with a qualified trainer or behaviourist alongside choosing the right equipment.

A Word on Safety First: Collars and Choking Hazards

Before we get into the options, something important that doesn't get said enough: all collars carry a choking risk, and this should be taken seriously for dogs and cats alike.

A collar that catches on furniture, fencing, or another animal's jaw can cause serious injury or worse in seconds. For this reason:

• Never leave a collar on an unsupervised pet — particularly cats, who are agile climbers and can get collars caught easily
• Always use a quick-release or breakaway collar for cats — these are designed to snap open under pressure
• Check the fit regularly — a collar that was right six months ago may have become too tight or too loose
• Consider removing collars at home and only putting them on for walks, keeping ID tags on a harness instead

For dogs who pull, a collar alone puts significant pressure on the neck and throat. Repeated pulling on a collar can cause damage to the trachea, cervical spine, and surrounding tissue over time. This is why, for most dogs, a harness is the safer and more comfortable choice.

Collar vs Harness: Which Is Right for Your Dog?

When a collar works well

A collar is perfectly appropriate for dogs with good lead manners who don't pull — like Bruch was. For a calm, well-trained dog on a standard lead, a well-fitted collar is comfortable, practical, and easy to use. It's also where you'll attach your ID tag, which is a legal requirement for dogs in public in the UK.

When a harness is the better choice

For dogs who pull, lunge, or are still in training, a harness distributes pressure across the chest and shoulders rather than concentrating it on the neck. This is significantly safer and more comfortable for your dog, and gives you better control without the risk of tracheal damage.

A harness is also a better choice for:

• Brachycephalic breeds (flat-faced dogs like French Bulldogs) who are already prone to breathing difficulties
• Puppies still learning to walk on a lead
• Dogs who have been attacked or have anxiety around other dogs
• Any dog who pulls consistently

Hugo wears a harness. It's non-negotiable for a dog like him — both for his safety and for ours.

Can Cats Go on Walks? Yes — With the Right Harness

This surprises a lot of people, but cats can absolutely be walked on a harness and lead — and for indoor cats, it can be a wonderful way to give them safe outdoor enrichment. Duke has his own harness, and while he approaches the whole experience with the air of someone who is doing you a favour, he genuinely enjoys the outdoor stimulation.

A few things to know about walking cats:

• Always use a cat-specific harness — never a collar. Cats can slip out of collars easily and a harness distributes any pressure safely across the body
• Introduce the harness slowly — let your cat wear it indoors first, for short periods, before attempting an outdoor walk
• Let your cat lead — cat walks are less about destination and more about sniffing, exploring, and experiencing the outdoors at their own pace. Follow their curiosity rather than directing them
• Choose quiet times and locations — busy streets, dogs, and loud noises can be overwhelming. A quiet garden or park in the early morning is ideal
• Never leave a harnessed cat unsupervised outdoors

Not every cat will take to harness walking — some simply aren't interested, and that's fine. But for curious, confident cats, it's a brilliant form of enrichment.

Types of Lead: Choosing the Right One

Standard lead

A fixed-length lead — usually 1.2 to 1.8 metres — gives you consistent control and is ideal for training, busy areas, and dogs with reliable lead manners. This was Bruch's lead of choice, and it suited him perfectly. Also suitable for cat walks.

Retractable lead

A retractable lead gives your dog more freedom to explore while keeping them technically on lead. Hugo uses one in appropriate settings — it gives him the freedom to sniff and roam while I maintain control if needed.

However, retractable leads come with important caveats:

• They should never be used in busy areas, near roads, or around other dogs you don't know
• The thin cord can cause serious rope burns to hands and legs if it wraps around skin
• They offer less control in an emergency than a fixed lead
• They are not suitable for dogs who pull hard or lunge

Training lead / long line

A long line (typically 5–10 metres) is brilliant for recall training in open spaces. It gives your dog the feeling of freedom while you maintain a safety net.

Enclosed and Designated Areas: A Game Changer for Anxious Dogs

If your dog has been attacked, has anxiety around other dogs, or simply has the escape artistry of a small furry Houdini, designated enclosed dog fields are one of the best investments you can make in their wellbeing. Many areas across the UK now have these facilities — a quick search for "enclosed dog field" plus your location will usually bring up options nearby.

Walking Your Dog Is a Commitment — And One Worth Making

Getting a dog is one of the most rewarding things you can do. It's also a genuine responsibility — and one that doesn't pause for bad weather, busy days, or early mornings. If it rains, put on a raincoat and go anyway. Your dog doesn't get a day off from needing to move, sniff, and explore the world.

Check the Ground Before You Walk in Hot Weather

In warm weather, pavement and tarmac can reach temperatures that cause serious burns to your dog's paws in minutes — even on days that don't feel that hot to us. Use the 5-second rule: place the back of your hand on the pavement for five seconds. If it's too hot for your hand, it's too hot for your dog's paws. Walk early morning or after sunset, and stick to grass and shaded paths where possible.

Always Carry Water — But Offer It Carefully

Always carry fresh water for your pet on every walk, regardless of the weather. Dogs and cats can dehydrate faster than you might expect, particularly during exercise.

However — and this is important — offer water in small amounts rather than letting your dog drink a large quantity at once, particularly during or immediately after exercise. Drinking large volumes of water rapidly can contribute to bloat (Gastric Dilatation-Volvulus or GDV) — a serious and potentially life-threatening condition, particularly in deep-chested breeds. Offer small sips regularly rather than a full bowl in one go.

Never Exercise Directly Before or After Food

This is one of the most important rules of dog ownership and one that isn't talked about enough. Never exercise your dog immediately before or after eating. Vigorous exercise on a full stomach — or eating a large meal immediately after exercise — significantly increases the risk of bloat.

As a general guide:

• Wait at least 1–2 hours after a meal before exercising your dog
• Allow your dog to rest and cool down after exercise before feeding
• This applies to both dogs and, to a lesser extent, cats

Bloat can develop rapidly and is a veterinary emergency. If your dog shows signs of a distended abdomen, unproductive retching, restlessness, or distress after eating or exercise, seek veterinary attention immediately.

Bruch taught me that a walk is never just a walk. It's the highlight of your dog's day. Hugo, for all his chaos, reminds me of that every single time we head out. Love your dog. Care for them always. Invest in the right equipment — but more than that, invest your time, your patience, and your presence. That's what they're really asking for.
