Choosing the right carrier for your small dog isn't just about convenience—it's about safety, comfort, and matching the carrier style to how you actually move through the world. A carrier that works perfectly for a quick café run won't necessarily work for a transatlantic flight.
Here's a breakdown of the main carrier types, what they offer, and how to decide what works best for your lifestyle.
Sling Carriers
What it is: A fabric pouch worn across your body like a crossbody bag, with your dog nestled against your chest or hip.

Cons:

What to look for: Adjustable strap, breathable mesh panel, internal safety clip to attach to harness, padded shoulder strap, machine washable fabric.
Backpack Carriers
What it is: A structured backpack with your dog riding on your back, facing backward or with a bubble window to look out.

What to look for: Structured base (prevents sagging), breathable mesh panels, internal safety tether, padded shoulder strap, wipeable interior lining, pockets for essentials, reinforced handles.
Wheeled Carriers (Rolling Carriers)
What it is: A carrier on wheels that you pull behind you like luggage, with the option to carry it by hand or wear as a backpack (in convertible models).
Pros:

What to look for: Smooth-rolling wheels (preferably 360° swivel), convertible backpack straps, telescoping handle, airline-approved dimensions, ventilation on multiple sides, removable fleece pad.
Soft-Sided Airline-Approved Carriers
What it is: Collapsible, soft fabric carrier specifically designed to fit under airplane seats. Usually rectangular with mesh sides.

What to look for: Airline-approved dimensions (check your specific airline), mesh panels on at least three sides, padded bottom, top and side entry, collapsible frame, meets airline ventilation requirements, shoulder strap and top handle.
Sizing: Most airlines require carriers under 46cm L × 28cm W × 24cm H, but this varies. Measure your dog (length + height) and check airline requirements before buying.
Hard-Sided Carriers (Crates)
What it is: Rigid plastic or hard shell carrier with a metal door. Standard design for cargo travel or car transport.
Pros:

Pros:

- Usually well-designed with lots of features
- Good investment for frequent travelers
Cons:

Best for: Frequent travelers, owners who use multiple transport modes (car, plane, train, walking), those who want one high-quality carrier for everything.
Which Carrier Type Is Best for Small Dogs?
There's no universal "best"—it depends on your dog's size, temperament, and how you plan to use it.
Consider:
Your dog's weight and size:
- Under 3kg → Sling or shoulder bag
- 3-6kg → Backpack, sling, shoulder bag, or airline-approved soft-sided
- 6-10kg → Backpack or wheeled carrier
- 10kg+ → Wheeled or hard-sided only
Your dog's temperament:
- Anxious or clingy → Sling (close to your body)
- Calm and observant → Backpack or shoulder bag
- Active and squirmy → Structured backpack or hard-sided
- Nervous about enclosed spaces → Open-top tote or sling
Your primary use:
- Air travel → Soft-sided airline-approved or wheeled (convertible backpack)
- Hiking/outdoor → Backpack with waist support
- Urban errands → Sling or shoulder bag
- Car travel → Hard-sided crate (secured with seatbelt)
- Long-distance travel → Wheeled carrier or backpack
- Quick trips → Sling
Your physical needs:
- Back or shoulder issues → Wheeled carrier
- Need hands completely free → Backpack
- Want style + function → Shoulder bag/tote
- Prioritize comfort for long wear → Backpack with waist belt
Carrier Safety Checklist
Regardless of type, every carrier should have:
✓ Proper ventilation (mesh on at least two sides, ideally three)
✓ Internal safety tether (clips to harness to prevent escape)
✓ Secure closures (zippers, snaps, or Velcro that won't accidentally open)
✓ Washable or wipeable interior (accidents happen)
✓ Comfortable padding (especially on the bottom)
✓ Appropriate size (your dog can stand, turn around, and lie down—not too big or too small)
✓ Durable construction (reinforced stitching, quality materials)
✓ Comfortable straps for you (padded, adjustable)
Carrier Training Tips
Most dogs don't naturally love carriers. Here's how to build positive associations:
- Start early: Introduce the carrier weeks before you actually need it
- Make it inviting: Place treats, favorite toys, or meals inside
- Leave it open: Let your dog explore voluntarily—never force them in
- Short sessions: Start with 30 seconds inside, gradually increase
- Positive associations: Carrier = treats, not just vet visits
- Practice carrying: Walk around the house with your dog inside before going out
- Gradual exposure: Short trips first (5 minutes), then slowly extend duration
FAQ: Dog Carriers for Small Dogs
Q: What size carrier does my dog need?
A: Measure your dog from nose to base of tail (length) and floor to top of head when sitting (height). Add 5-7cm to each measurement. Your dog should be able to stand, turn around, and lie down comfortably.
Q: Can I use a regular backpack or bag as a dog carrier?
A: Not safely. Regular bags lack proper ventilation, structural support, and safety features like internal tethers. Always use a carrier designed for pets.
Q: How long can my dog stay in a carrier?
A: Depends on the situation. For flights, dogs can handle 3-4 hours if properly sized. For daily use, take breaks every 1-2 hours for bathroom, water, and stretching. Never leave a dog in a carrier for extended periods without breaks.
Q: My dog hates being in a carrier. What can I do?
A: Start slow with positive reinforcement. Feed meals inside, leave it open in your living room, use high-value treats. Some dogs need weeks or months to feel comfortable. Never force them—it creates negative associations.
Q: Should the carrier be big enough for my dog to move around?
A: Yes, but not too big. They should be able to stand, turn around, and lie down, but excess space can be dangerous during sudden stops or turbulence. Snug is safer than spacious.
Q: Can I carry two small dogs in one carrier?
A: Only if the carrier is designed for multiple dogs and both dogs are comfortable together. They must be able to move without crowding each other. Check airline rules if flying—many allow only one pet per carrier.
Q: Are bubble backpacks safe?
A: Generally yes, if well-ventilated and properly sized. The bubble window shouldn't be the only ventilation source. Avoid in very hot weather (greenhouse effect). Not all dogs enjoy the exposure—some find it stressful.
Q: How do I clean a dog carrier?
A: Most soft carriers have removable, machine-washable pads. Wipe down the carrier itself with pet-safe cleaner. Hard-sided carriers can be hosed down or wiped thoroughly. Air dry completely before next use.
Q: Can I use a carrier as a crate at home?
A: For short-term containment (hotel rooms, visiting family), yes. For long-term crating at home, a larger, more comfortable crate is better—carriers are designed for transport, not all-day containment.
Q: What's the difference between a pet carrier and a pet stroller?
A: Carriers are worn or carried; strollers are wheeled and your dog rides inside (like a baby stroller). Strollers are good for senior dogs, injured dogs, or very long outings, but less portable than carriers.
Q: Do I need different carriers for different situations?
A: Not necessarily. A good convertible backpack can handle most situations. But if you frequently fly AND do daily urban errands, you might want both an airline-approved carrier and a compact sling.
Q: Are expensive carriers worth it?
A: Usually, yes—better materials, durability, comfort (for both you and your dog), and safety features. A quality carrier lasts years. Cheap carriers often have poor ventilation, uncomfortable straps, and break quickly.
Q: My dog gets motion sick in carriers. What can I do?
A: Choose a carrier where they can see out (reduces motion sickness). Avoid feeding right before travel. Take frequent breaks. Talk to your vet about anti-nausea medication for longer trips.
