Small dog owners face a problem that large dog owners never think about: dogs can't go everywhere on their own four feet. The underground at rush hour. A shop with hard floors and hundreds of feet. A music festival. A long day of errands that includes a café that allows pets but not dogs on the ground. An elderly small dog whose joints have started to struggle on long walks but who still loves an outing.
The solution isn't to leave the dog at home — it's to carry them. And for small dogs (up to about 10kg, depending on the carrier), a purpose-designed dog backpack carrier changes what's possible entirely. The Little Chonk — sometimes called the "Little Chonk" — is one of the better-designed options on the market, and it's worth understanding why.
What the Little Chonk is (and what it isn't)
The Little Chonk is a structured backpack carrier designed for small dogs. The core design philosophy is that the dog travels facing forward, with their head out of the top of the pack, or alternatively secured inside with a mesh window. Unlike a sling or a shoulder bag carrier, it distributes weight across both of the owner's shoulders — critical for anything beyond a short walk.
It's not a hiking carrier (those are built for much larger loads and different weight distribution). It's not a soft-sided travel bag for flight cabin use (though some configurations meet airline size requirements). It sits somewhere in between: a stylish, practical carrier for urban life, public transport, and day-to-day situations where a small dog needs to travel without walking.
The "chonk" in the name gives a clue about the intended occupant — a chunky small dog rather than a toy breed. Think French Bulldog, Pug, Dachshund, or a larger Chihuahua. The generous internal space and ventilation matter more for a compact but stocky body type than for a slender Papillon.
Why dog backpack carriers solve a genuine problem
Let's be specific about the situations where a carrier genuinely changes what's possible:
- Public transport. On the London Underground and many bus networks, dogs must be carried or in an enclosed carrier. A backpack that your dog travels in comfortably means you can actually use public transport with your pet — and both of you arrive calmer than if you'd fought through a crowded platform with a dog trying to lead-walk through a tide of feet.
- Businesses that allow pets-not-on-floor. A surprisingly large number of shops, cafés and other businesses have a "pets welcome but must be carried or in a bag" policy. This is especially common in food service environments where floor-level dogs create hygiene concerns. A carrier means your dog can come with you without the awkward "sorry, they need to be off the floor" conversation.
- Long-day outings. A full day at a market, a festival, or a long trip by coach or train is a lot for a small dog's legs. Carrying them for the tired portions — even if they walk for the active parts — extends what you can do together significantly.
- Senior or mobility-limited dogs. An older small dog who struggles with distance but still benefits from stimulation and company is a natural fit. They walk when they want to, get carried when they've had enough, and enjoy the outing without the pain of overdoing it.
- Veterinary trips. Carrying a small dog in a backpack rather than a hard carrier is typically much less stressful for both dog and owner. The dog is close to the owner's body, can see and smell their environment, and isn't enclosed in a box.
What makes the Little Chonk stand out
Dog backpack carriers are not all equal. Poorly designed ones are uncomfortable for the dog (no padding, poor ventilation, the dog slides to the bottom), uncomfortable for the owner (all weight on the shoulders, no sternum strap), or both.
The Little Chonk addresses the key comfort issues with a padded interior base, mesh sides for airflow, and a design that keeps the dog upright rather than slumped. For a French Bulldog — a breed that overheats easily — ventilation isn't optional. The mesh panels matter.
The fit for the owner is handled with adjustable straps and a waist belt on some configurations. Carrying 6–8kg on your shoulders for 20 minutes sounds trivial until you've actually done it without proper weight distribution — it's exhausting. A properly fitted backpack carrier with waist support is genuinely comfortable for a two-hour urban outing.
"We started using it on the commute to take Biscuit to his daycare drop-off rather than the car. It's completely changed our mornings — he sits in it perfectly happily, no pulling on leads through crowds, and we both arrive calmer."
— French Bulldog owner, London
Getting your dog comfortable with a carrier
A carrier is only useful if your dog accepts it, and the first time a dog is placed in an enclosed backpack — lid closed, picked up, and carried — most dogs find it strange or alarming. The introduction needs to happen gradually.
Start with the carrier open on the floor, treats placed inside, and let the dog explore it voluntarily. After a few sessions, start zipping it partially closed while the dog is inside, rewarding calmly. Then pick up the carrier briefly — just a few seconds at first — and reward on coming out. Building this over a week or two means the dog associates the carrier with calm and treats, not with stress.
For the head-out configuration, most dogs adapt quickly once they've been in it a couple of times — they can see, smell and hear everything, which is generally less stressful than an enclosed carrier. The first trip should be short and positive: a walk around the block, not a two-hour tube journey.
Weight limits and sizing
Carrier weight limits aren't arbitrary — they reflect what's structurally safe for the bag and what's ergonomically manageable for the carrier. The Little Chonk's stated limit means being honest about your dog's weight before purchasing. A 12kg dog is a 12kg dog; rationalising that "he's mostly muscle" doesn't make the carrier any stronger.
Measure your dog's chest girth and length before buying any carrier. A dog who fits the weight limit but is long-bodied (Dachshund) needs a carrier with enough internal length — a carrier sized for a compact dog of the same weight won't be comfortable. Most carrier specifications include interior dimensions as well as weight limits, and both matter.
As a recommendation from your kennel or daycare
If you work in pet care, a dog backpack carrier is genuinely worth recommending to clients with small dogs. Not as a sales pitch — as practical advice based on knowing their dogs. The clients who drive 20 minutes each way to drop their dog at daycare because they can't take them on the tube are good candidates. So are clients whose older small dogs are starting to struggle on walks but still love being included.
A kennel that knows its clients well enough to recommend the right products for their lifestyle is a kennel those clients stay with. Product recommendations, done honestly, are a form of expertise — and expertise builds the trust that produces long-term client relationships.
