The Amazon Basics Portable 2-Door Hard-Sided Pet Carrier is our top pick for most buyers. Its two-door layout makes it the best medium dog carrier for easier loading, access, and quick checks during travel. The hard plastic shell provides everyday structure, while metal wire doors and ventilation openings support airflow and visibility. This carrier suits car rides, vet visits, and short trips, not long walks where a soft bag may feel easier to carry.
This guide is for owners who need a secure carrier for a medium-sized dog and want clear choices before buying. Focus first on interior size, since your dog should stand, turn, and lie down comfortably. Then check the shell material, door strength, ventilation, and listed weight limit. The four picks below are ranked with reasons and honest drawbacks for each, helping you match a design to your dog, vehicle, and travel routine.

4 Top Medium Dog Carriers
This ranked list counts down from the fourth choice to the top medium dog carrier, with each pick matched to different needs.
4. Henkelion Pet Carrier for Small Dogs and Cats
Best for: small pets on short flights
The Henkelion soft-sided carrier is made for cats, puppies, and small dogs up to 15 pounds. It uses lightweight polyester fabric and has mesh panels on all four sides, so pets get airflow while owners can check on them. The carrier folds for storage and includes padded handles plus an adjustable shoulder strap. Its black exterior is listed as waterproof, which can help with light spills during travel.
The listed interior size is 15 by 9 by 9 inches, but the pet should be smaller than those measurements. Body length and standing height matter more than weight alone. Two connecting handles can work with a luggage strap or seat belt, and the shoulder strap allows hands-free carrying. The design is described as airline approved, although each airline sets its own size and pet rules. At around $28, it costs less than many hard carriers, but space is limited for medium-sized animals.
Pros
- Four mesh sides improve airflow and visibility during trips.
- Foldable construction makes storage easier in small homes or cars.
- Two connecting handles can attach to luggage straps or seat belts.
Cons
- The 15-by-9-by-9-inch space may feel cramped for some 15-pound pets.
- Airline acceptance can vary, so buyers must check the carrier’s current rules.
3. Noah & Paw Dog Sling Carrier
Best for: Small dogs needing hands-free outings
The Noah & Paw Dog Sling Carrier is a soft, over-the-shoulder carrier for small dogs and cats. It supports pets from 5 to 18 pounds, or about 2.2 to 8 kilograms, making it a fit for short walks, errands, and travel. The outer fabric uses twill, while a fur lining adds a softer contact surface. Its padded shoulder strap adjusts in length, so adults and children can set a comfortable carry position. That flexibility helps when more than one person uses the sling.
Safety gets more attention than in a basic pet pouch. A built-in safety belt connects to your pet, then snaps closed as a second securing step. This setup can help limit sudden jumps, though owners still need to supervise their pet. A magnetic pocket holds small items such as a phone, keys, treats, or waste bags. The carrier is machine washable, which helps after muddy walks or shedding. At around $25, it offers useful features for routine outings, but it remains a simple sling rather than a structured travel crate.
Pros
- Fits small pets from 5 to 18 pounds.
- Adjustable padded strap suits different users.
- Double safety system adds belt and snap closure.
Cons
- Not suitable for dogs weighing more than 18 pounds.
- Soft sling construction provides less structure than a crate-style carrier.
2. Henkelion Soft-Sided Pet Carrier
Best for: Small pets on car or air trips
The Henkelion soft-sided carrier is made for cats, puppies, and small dogs up to 15 pounds. It uses lightweight polyester fabric, four mesh sides, and a collapsible frame for easier storage. Two connecting handles can work as carry grips, a luggage strap, or a way to secure the bag with a vehicle seat belt. The listed price is around $23, though it can change.
A padded shoulder strap supports hands-free carrying, while the mesh panels let you check on your pet during travel. The carrier is listed as waterproof, but the soft design offers less structure than a hard kennel. Its recommended pet space is about 15 by 9 by 9 inches, so body length and height matter more than weight alone. For cabin travel, the stated maximum size is 18 by 11 by 11 inches. Airline rules differ, so confirm the measurements with your airline before leaving.
Pros
- Four mesh panels improve airflow and let you monitor your pet.
- Two handles and a padded shoulder strap offer several carrying options.
- The foldable polyester body takes less storage space after travel.
Cons
- The interior is compact, and pets near 15 pounds may not fit comfortably.
- Soft sides provide less protection and support than a rigid carrier.
1. Amazon Basics Portable 2-Door Hard-Sided Pet Carrier
Best for: Cats and 12–20-pound dogs
This hard-sided carrier measures 22.8 by 15 by 13 inches, giving cats and smaller dogs a roomy travel space. Its plastic shell uses steel-wire doors, while screws connect the upper and lower sections. The carrier has two entry points: a front door and a top door. That setup can help with loading a nervous cat or lifting a small dog inside.
The top door opens to either side and uses spring-loaded latches for one-handed operation. A carry handle sits above it, making short trips to the car or vet easier. Ventilation openings cover the sides, top, and back, so air can move through the enclosure from several directions. Around $50, it offers useful features for routine travel without moving into premium pricing. Still, measure your pet’s body length and height before ordering. The 12-to-20-pound guideline is only a reference, not a substitute for proper fit.
Pros
- Two doors provide front and top access for easier loading.
- Screws and durable plastic keep the two carrier sections connected.
- Side, top, and rear vents allow airflow during trips.
Cons
- The 13-inch height may not fit taller pets comfortably, even within the listed weight range.
- The hard plastic shell takes more storage space than a collapsible fabric carrier.
Buying Guide
The most important factor is a secure, correctly sized fit. A carrier should support your dog’s full weight while giving enough room to sit, turn around, and lie down without shifting during travel.
- Size and weight limit: Measure your dog’s back, chest, and standing height, then compare them with the carrier’s interior dimensions. Choose a model rated at least 5 pounds above your dog’s weight.
- Ventilation: Look for mesh panels on at least three sides, especially near your dog’s face. For car trips longer than 2 hours, airflow matters as much as interior space.
- Interior support: A rigid base prevents sagging and protects joints. Choose a removable pad at least 1 inch thick, with a washable cover for accidents and shedding.
- Safety features: Select locking zippers, reinforced seams, and an internal tether that attaches to a harness, not a collar. For car use, confirm the carrier fits securely with the seat belt.
- Portability and cleaning: Shoulder straps work for short walks, while padded handles help with heavier dogs. A carrier under 8 pounds is easier to lift, and water-resistant fabric simplifies cleanup.
If you cannot have everything, prioritize accurate sizing and a firm, stable base over extra pockets or decorative features.
Frequently Asked Questions
How do I choose a medium dog carrier?
Choose a medium dog carrier by matching its interior length, width, and height to your dog’s measurements, then check the stated weight limit. Measure from your dog’s nose to the base of its tail and from the floor to the top of its head. Add a few inches for turning and posture.
What size carrier does a medium dog need?
A medium-sized dog needs a carrier that lets it stand, turn around, and lie down without pressing against the sides. As a starting point, compare your dog’s measurements with carriers around 24 to 30 inches long, but follow the listed interior dimensions instead of relying on labels such as medium or large.
Can I use a medium pet carrier for air travel?
You can use a medium pet carrier for air travel only if its dimensions, construction, and loaded weight meet the airline’s current rules. Many cabin carriers must fit beneath the seat, and limits often vary by aircraft. Check the airline’s pet policy before buying, especially for a carrier longer than 20 inches.
Are hard or soft carriers better for medium dogs?
Soft-sided carriers are usually better for cabin trips and storage, while hard-shell models provide firmer protection and simpler cleanup. A soft bag may fold into a smaller space, but it can collapse if your dog leans against the walls. Hard carriers often weigh more, with some medium models exceeding 10 pounds.
Conclusion
Amazon Basics Portable 2-Door Hard-Sided Pet Carrier is the top pick for owners who want a practical, enclosed kennel for medium dogs during car trips, vet visits, and short moves. If your priority is lighter carrying or more ventilation, choose a soft-sided carrier instead, since fabric models usually weigh less and can offer wider mesh panels, though they may provide less impact protection and structure. Before buying, double-check your dog’s length, height, and weight against the carrier’s interior dimensions, confirm that the crate fits your vehicle and meets any airline or transport rules, verify the package quantity if you need more than one, and compare the current price across sellers because listings and discounts can change.
