Review: Comfortable for both the pup and the dog parent - My pup is small so I ordered a small. I feel the sizing might be a little off because I’m not sure if she fits in it properly. She seems to be a little bigger in a size small than I expected. Even though I am unsure of the size, I will say this is the second carrier I’ve ordered from this seller. The bags are sturdy, comfortable to wear and my other small pup seems to enjoy being in his carrier when we are on the bicycle. I like that it has a water bottle holder on each size and it’s easy to get your pup in the carrier. The ventilation is good for my pups and they seem comfortable. Good quality zippers, not cheaply made, and great functionality for hiking, riding, or even walking around the store.
Review: Great back pack - Great way to bring our dog with us 6.5 lbs She love to ride in it . It’s made very well.

## Features

- TRAINING CARRIER - Designed with a minimal frame & breathable mesh siding, the Trainer is the perfect way to introduce your small dog and/or puppy to backpacks. It will fit most comfortably on dog owners with small to medium builds.
- FIND THE RIGHT SIZE - The Large is best for dogs with a length of 20-22” from collar to the base of the tail. Typical dog breeds that will fit this size backpack include Australian Shepherd, Small Labradoodle, Border Collie, Brittany & Terrier.
- FOR CASUAL, SHORT-TERM USE - In addition to early-stage training, this carrier is great for quick, everyday outings when walking them doesn't work—commuting, cycling, vet trips, a quick walk on hot pavement, or maybe just when they get tired.
- SAFETY - Even though it’s only a temporary solution, the Trainer still comes with all our standard safety features, so you can count on the quality & peace of mind you enjoy with any other K9 Sport Sack purchase.
- COMFORT & MOBILITY - This ultra-lightweight backpack features a simplified design that ensures easy on/off use, an ergonomic structure to promote weight distribution, ventilated side panels, a lumbar support strap, and padded shoulder straps.

### ⭐⭐⭐⭐⭐ Comfortable for both the pup and the dog parent
*by A***M on March 16, 2025*

My pup is small so I ordered a small. I feel the sizing might be a little off because I’m not sure if she fits in it properly. She seems to be a little bigger in a size small than I expected.

### ⭐⭐⭐⭐⭐ Great back pack
*by S***R on January 14, 2026*

Great way to bring our dog with us 6.5 lbs She love to ride in it . It’s made very well.

### ⭐⭐⭐⭐ My doggie “Kat” loves her bag
*by A***R on November 26, 2024*

Although the pics don’t show this angle, I can tighten the shoulder straps to help boost her up more and she can look over my shoulder. Got this for my little dog who like to walk/hike with me but is getting older and can’t always hang in for the long haul. This is comfortable for both of us (although it’s warm), easy to get on off with help. I can get it on/off myself because I have a small 9lb dog, but it’s easier with help. I like the color too!
