Just came back from a weekend away and took Rosie with us. This K9 carrier was awesome. Lots of padding and adjustable straps for me and lots of comfort for her. She loves being with us when we’re taking long walks and hikes. Really well made – highly recommend.

We’re so happy to hear this carrier was a hit. Happy trails!

My senior puppy has reached the point of no longer being able to hike with us, but still wants to go. This makes it easier. Getting him in was simple enough (he’s also super chill and lets me do whatever with him). He does weigh Bout 85 pounds, so carrying him is a little hefty, but we’re working on it. It does help to have a second person to hold him and the bag upright while I get it adjusted in my shoulders sitting down before standing with him.
My Wholesome Pet –
Thanks for sharing your experience. Here’s to more adventures.

Fits my bug doodle well. He’s pushing it on the size but only weighs 65lbs. He was a good boy for getting in and i think he even had fun.
