If you love the outdoors but prefer a smaller dog, you’ll quite rightly wonder which small dogs are best for hiking. The good news is that plenty of smaller breeds are perfectly capable of keeping up on the trail. While they might not match the endurance of a Border Collie or Labrador, many small dogs have surprising stamina, agility, and enthusiasm for adventure.
In this guide, we’ll look at some of the best small breed dogs for hiking. We’ll exploring why they’re great on the trail, what to expect as an owner, and any special needs or considerations.
Authors Insight: I grew up in a family where we only ever had small dogs, and yet we’ve always been active taking on long hikes safely. Our first dog, Travis, was a Jack Russell Terrier and was the very typical big dog in a small dogs body associated with the breed. Hardy, experienced and full of energy, he took on Mount Snowdon with no issues whatsoever, which by definition would qualify him for most hikes in the UK. No surprise considering this that Jack’s are the number 1 pick in this list.
1. Jack Russell Terrier
Why they’re great on the trail:
Jack Russells are fearless, athletic, and full of energy. Originally bred for fox hunting, they thrive on activity and love challenging terrain. Their compact size lets them scramble over rocks, jump fallen logs, and handle long days out far better than most people expect.
Temperament / nature:
Smart, confident, and endlessly curious. They’re often happiest when they’ve got a “job” to do, and a day out hiking fits that perfectly. They’re also very trainable due to a higher intelligence level than many would think.
Suitability for ownership:
They’re not a breed for the laid-back owner. Jack Russells need consistent training, structure, and plenty of exercise every single day. A common issue is that owners wrongly think they’re a small breed that therefore won’t need much exercise, and it’s these scenarios that can lead to behavioural issues. This is not a breed that’s content to laze around the house all day!
Special requirements:
Because of their strong prey drive, recall training is essential before letting them off-lead. You’ll also need to manage their energy levels, because a bored Jack Russell will find its own entertainment.
2. Miniature Schnauzer
Why they’re great on the trail:
Miniature Schnauzers are sturdy and spirited, with enough endurance for long walks and moderate hikes. Their wiry coat sheds minimally and provides some weather resistance. Ideal for the mixed conditions of the British countryside. And, let’s be honest, how could you not love a dog that has such a magnificent moustache.
Temperament / nature:
Friendly, alert, and intelligent. They bond closely with their owners and enjoy being part of family adventures.
Suitability for ownership:
They adapt well to both home and outdoor life, but regular exercise is key. A good hike or two each week helps balance their energy and keeps them mentally sharp.
Special requirements:
Their beards and furnishings can trap dirt and seeds, so some post-hike grooming is needed. They’re also vocal dogs — early training helps manage that.
3. Border Terrier
Why they’re great on the trail:
Built for stamina and versatility, the Border Terrier is one of the toughest small dogs around. They’re equally happy on rocky paths, open moorland, or woodland trails.
Temperament / nature:
Good-natured, loyal, and easy-going — often less fiery than other terriers. They tend to get along well with other dogs too.
Suitability for ownership:
Borders thrive with active owners who enjoy the outdoors. They’re relatively low-maintenance at home but need daily activity and strong boundaries.
Special requirements:
Like most terriers, they have a strong prey instinct, so recall work is vital. Their coarse coat benefits from hand-stripping or regular grooming to prevent matting.
4. Cairn Terrier
Why they’re great on the trail:
Commonly referred to as Scotlands oldest working dog, the compact but robust, Cairn Terriers were bred for rugged highland terrain — exactly the kind of environment where many people hike today. They love exploring new scents and handle cold, damp weather surprisingly well.
Temperament / nature:
Cheerful, hardy, and independent. They often have big personalities packed into small bodies.
Suitability for ownership:
Ideal for owners who enjoy daily walks and weekend adventures. They can adapt to smaller homes but need regular outdoor time to stay balanced.
Special requirements:
They can be stubborn, so patient and positive training is essential. As with most terriers, early socialisation helps manage their boldness.
5. Beagle
Why they’re great on the trail:
Though slightly larger than some of the others here, Beagles are still a compact, medium-small breed that loves to hike. Their endurance is impressive, and their friendly temperament makes them excellent companions for long walks.
Temperament / nature:
Gentle, curious, and affectionate. They love people, dogs, and being part of a pack.
Suitability for ownership:
Beagles are perfect for active families or solo adventurers who want a social, trainable dog that’s always up for exploring. Often referred to as escape artists, beagles can jump higher than you would imagine so training is essential.
Special requirements:
Their nose often takes the lead, so strong recall is important. They can be prone to weight gain if not exercised enough — hiking is a great way to keep them lean.
6. Cocker Spaniel (Show or Working Type)
Why they’re great on the trail:
Spaniels are natural explorers. Their small-to-medium size, endless energy, and love of water make them brilliant hiking partners.
Temperament / nature:
Affectionate, enthusiastic, and eager to please. Cocker Spaniels are sensitive dogs that thrive on positive reinforcement and companionship.
Suitability for ownership:
They need a lot of mental stimulation and exercise, but they’ll give it all back in loyalty and joy on every adventure.
Special requirements:
Their feathered coat needs brushing after hikes to prevent burrs and mats. Working Cockers, in particular, have higher stamina and need plenty of training and structure.
7. Welsh Terrier
Why they’re great on the trail:
Tough and athletic, the Welsh Terrier is built for activity. They have the confidence and endurance to keep up on long, uneven hikes, but their smaller frame makes them easy to manage.
Temperament / nature:
Friendly but determined. They’re playful dogs with an independent streak, making them great fun on adventures.
Suitability for ownership:
Perfect for someone who wants a smaller hiking dog with a terrier’s drive and character.
Special requirements:
They need firm but fair training and plenty of consistency. Grooming is moderate — their wiry coat benefits from stripping or clipping.
A Note on Hiking with Small Dogs
Smaller breeds can absolutely enjoy the trail — but they do need a bit more care:
- Watch for fatigue: Little legs mean more steps; rest often on long routes.
- Temperature awareness: Small dogs lose heat faster, so pack an extra layer in winter and plenty of water in summer.
- Terrain considerations: Avoid high stiles or steep descents if your dog isn’t confident with them.
- Gear: Make sure you have the correct dog hiking equipment. A well-fitted harness and collapsible water bowl make all the difference.
Final Thoughts
Choosing a dog breed that’s suited to hiking and your lifestyle is crucial. Many small dogs can make exceptional hiking partners — full of courage, curiosity, and love for adventure. Whether you choose a spirited Jack Russell or a hardy Border Terrier, the key is to match their personality to your lifestyle. With the right preparation and care, a smaller breed can keep up on almost any trail and bring just as much heart to the adventure as their larger counterparts.
If you have reviewed this list and you’re left feeling that you might have a bit more space in your life, medium dog breeds can make the best all round hiking companions.
