Customers say
Customers find the dog carrier to be of good quality, sturdy, and comfortable, with one mentioning their dog enjoys being snug and up high in the pack. The carrier is easy to use and works well, with one customer noting it’s great for hiking adventures. However, the size receives mixed feedback, with several customers finding the large size too small, and the zipper quality is concerning as multiple customers report it breaking almost immediately.
