    Love this carrier. Roxie enjoys the rides and I enjoy her company. Works well for taking her to places that are crowded since she’s so small. Thank you.

    Nice pack!

    We bought the small pack for our 16 1/2 year old Cavalier/Terrier mix. She can’t walk far due to her aged heart, but LOVES getting into the pack to go smell/see the world as we walk for her. No problems getting in/out (but we use two people for the process.) Her head kind of lolled back so we put a bit of a cardboard support outside the pack for support and it works great (think of the head and side-head support in a child’s car seat). I think it’s our dog’s issue (weak, geriatric neck) and we/she are fine with this tweak. Thank you for freedom for all of us!

    Our little puppy immediately adapted to this wonderful backpack. We were amazed at how happy & content he remained during all the hiking we did on our New England / Acadia trip!!

    Almost perfect

    this is an upgrade to our old very simple back pack for training our little pup. the only thing keeping this from being 5 out of 5 is the front strap. I thought it was more across the waist lower chest but it actually sits around my throat. if it wasn't for this it would be perfect
