Quick verdict
Common Mistake: A lot of people assume that Mr. Pen Pet Carrier Backpack review is simple, but overlooking small details often leads to frustration. Avoid skipping the fundamentals!
You’ll find that the Mr. Pen- Pet Carrier Backpack, Weighing Up to 12 lbs, Adjustable Dog Carrier Backpacks is a solid option if you want to carry your small dog or cat hands-free and comfortably. It’s lightweight, breathable, and designed so you can carry your pet on your front or back, giving both you and your pet flexibility depending on your activity or mood.
What this product is and who it’s for
You can use this carrier for small and medium pets up to about 12 lbs; that’s the recommended upper limit to keep both you and your pet comfortable. If your dog is larger or heavier than that, you’ll likely feel strain and your pet may feel cramped — so this backpack is best for toy breeds, small mixed breeds, kittens, and small adult cats.
Key features at a glance
You’ll appreciate the main features at a glance: breathable mesh panels, a thick sponge padding for comfort, adjustable wide shoulder straps, a padded back panel, and the ability to wear it on your front or back. Those features combine to increase air circulation for the pet, reduce pressure for you, and boost the pet’s sense of security while being carried.
Design and build quality
You’ll notice the design is straightforward and functional, focused on comfort and ventilation. The backpack uses breathable mesh to promote airflow and a thick sponge for cushioning, and the adjustable straps let you dial in a fit that feels secure for both of you.
Materials used
The carrier uses a breathable mesh fabric along with a thick sponge padding in the body and straps. You’ll find these materials durable enough for everyday use like short hikes, bike rides, and trips to the park, while remaining lightweight for portability.
Construction and seams
The seams and stitching are generally good for a product in this category, and you’ll appreciate reinforced stitching at stress points like the strap attachments. That said, you should inspect seams regularly if you use it often or with a pet that tends to scratch or chew.
Comfort for your pet
Your pet’s comfort is a major priority with this design, and the breathable mesh plus sponge padding aims to keep your pet from feeling too hot or too restricted. The carrier allows your pet to sit upright or curl up depending on their preference.
Ventilation and airflow
The breathable mesh panels allow maximum air circulation, so your pet won’t feel too stuffy even when the backpack is closed. You’ll find that pets who overheat easily or are sensitive to closed spaces will generally appreciate the airflow.
Interior padding and support
A thick sponge padding inside the carrier helps keep your pet cushioned and supported. You’ll notice reduced jostling on uneven trails or while biking compared to a carrier that’s mostly fabric without padding.
Comfort for you
You’ll be carrying the backpack on your shoulders and back (or chest), so comfort for you is essential. The padded back panel and adjustable, wide shoulder straps reduce shoulder strain and distribute weight better than thin straps.
Straps and weight distribution
The straps are wide and adjustable, letting you tighten or loosen them to suit your body and the pet’s position. You’ll find the thickened sponge pad on the straps eases pressure on your shoulders, which matters most when you carry the pet for longer periods.
Carrying positions: front vs back
You can wear the backpack on your front side or your backside. You’ll likely prefer the front carry for nervous or older pets who want to be close to you, and the back carry for longer walks or when you want better balance during biking or hiking.
Weight limit and sizing
You should stick to the recommended weight limit of under 12 lbs for best comfort and safety. If you go over that, you’ll feel the extra burden on your shoulders and back, and your pet will likely feel less secure inside.
How to decide if your pet fits
Weigh your pet first and compare to the 12 lb limit; also check their length and chest size because some taller or long-bodied pets may not be comfortable even under the weight limit. You’ll also want to make sure they can sit or curl comfortably without their legs being tightly compressed.
Safety features
You’ll find practical safety elements like secure straps, a snug opening, and interior attachment points to anchor a harness or small leash. These features help prevent accidental escapes and keep your pet stable during movement.
Internal leash clip
The carrier often includes an internal leash clip or ring to attach to your pet’s harness; that way your pet can’t jump out suddenly when you loosen the top or open the carrier. You’ll want to always use a harness rather than a collar for this connection to avoid neck strain.
Secure closures and openings
Zippers and openings are designed to remain secure under normal use, but you’ll need to check them periodically for wear. You’ll also appreciate that the design minimizes wide openings where an excited pet could wriggle out.
Durability and maintenance
You’ll likely find the materials are durable enough for typical outdoor activities. To keep the carrier in good shape, you’ll want to follow simple cleaning and maintenance steps.
Cleaning and care
The breathable mesh and sponge padding can be spot-cleaned with mild soap and water. You’ll want to air-dry the carrier fully before storing to prevent mildew. For heavy dirt or shedding, a gentle brushing and occasional spot treatment will keep it fresh.
Longevity tips
Avoid exposing the carrier to prolonged direct sunlight or harsh chemicals, and check seams and zippers periodically. You’ll also want to keep your pet’s nails trimmed to reduce interior wear.
Portability and packing
You’ll find the carrier lightweight and easy to fold for storage when not in use. It’s convenient for carrying in a car or storing in a closet between outings.
Travel suitability
The backpack works well for a variety of short-to-medium trips: walking, light hiking, camping, biking (at moderate speeds on smooth paths), and quick vet visits. You’ll find it’s not a substitute for airline-approved carriers if you’re planning flying.
Use cases and scenarios
You’ll get the most value from this carrier when you use it for everyday adventures and short trips with your pet. Below are common scenarios where the pack shines.
Walking and casual outings
Wearing the carrier on your front or back makes it easy to pop your small dog in when they get tired on a long walk. You’ll appreciate not having to carry them awkwardly in your arms.
Biking and light hiking
For short or moderate rides and hikes, the backpack gives you hands-free mobility while keeping your pet secure and close. You’ll need to be cautious on rough terrain and limit ride intensity for your pet’s safety.
Vet trips and crowded areas
When you go to the vet or take your pet into crowded public spaces, the carrier keeps your pet close and less stressed by shielding them from excess stimulation. You’ll find it particularly useful for anxious pets that do better being near you.
Fit, adjustments, and getting your pet used to it
It may take a few sessions to get your pet comfortable stepping into the carrier and staying calm. You can use treats and short practice sessions to build positive associations.
Adjustment tips
Adjust the shoulder straps so the carrier sits snugly against your torso and the pet feels secure. You’ll want to make small adjustments and test with the pet inside until the fit feels balanced and comfortable for both of you.
Training your pet to accept the carrier
Start with short sessions of a few minutes, giving treats while the pet is inside, then gradually increase the duration. You’ll see the fastest progress if you use calm, reassuring tones and keep early experiences positive.

Common questions and answers
You’ll probably have a few questions before buying or using the carrier; here are answers to frequent ones.
Can this carrier be used for cats?
Yes, you can use the carrier for cats as long as they are within the recommended weight limit and are comfortable being carried. You’ll want to use a harness rather than just a collar.
How do you keep the pet from scratching the mesh?
Keep your pet’s nails trimmed and consider a removable interior pad to protect the mesh. You’ll want to check the interior regularly for any signs of damage.
Is the carrier machine washable?
The materials are best maintained with spot cleaning and air drying; machine washing could damage the padding or mesh. You’ll get longer life by hand-cleaning and avoiding harsh detergents.
Maintenance and storage
You’ll extend the life of the carrier by following a few simple maintenance practices.
Regular cleaning routine
Brush out loose hair after each use and spot-clean stains with mild soap. You’ll want to remove any trapped grit or small debris from seams and zippers.
Long-term storage
Store the carrier in a dry, cool area out of direct sunlight to preserve fabric and padding. You’ll also want to keep it folded but not crushed to maintain shape.
Troubleshooting common issues
You’ll likely encounter only a few minor problems and can troubleshoot them easily.
Strange odors
Air out the carrier and use mild, pet-safe cleaners if odors persist. You’ll want to avoid bleach or strong chemicals that can irritate both you and your pet.
Worn straps or loose stitching
Inspect seams and strap attachments regularly; if you spot wear, stop using the carrier until you repair or replace it. You’ll protect both your pet and yourself by addressing these issues early.
Alternatives and upgrades
If you find the weight limit or design doesn’t fit your needs, there are alternatives and upgrades to consider.
Larger or airline-approved carriers
If you need a carrier for bigger dogs or for flying, you’ll need models with higher weight limits and airline compliance certificates. You’ll likely pay more but gain functionality for travel.
Rigid frame backpacks
Some carriers have a more rigid frame and built-in suspension for heavier loads; you’ll find these are better for longer hikes with bigger pets but are bulkier and heavier when empty.
