    Worth it!

    I have a 20lb cockapoo and bought this to take him on bike rides. Pretty straightforward to get him on, he doesn't bark or anything and loves going for rides now. I was worried about quality but it seems decent and honestly I would have spent this if I only got 3 rides out of's that rewarding to be able to take him out for a ride.

    Best thing we have bought!

    We absolutely love the K9 Sac! Our 2 French Bulldogs really enjoy it. Now they can come biking with us all the time. So happy with this very well made product.

    1st one was defective

    The neck strap on 1st one I ordered was not attached properly, it came off when I tried to tighten it & I had to send it back. Ordered another one but was sold out of the color I wanted so I had to get a different color. The 2nd one I received seems ok but the shoulder straps seem to sit a little high and could be designed a little better, when you tighten them up to where they should sit, the dog feels a little top heavy, however it did mention this in many reviews. All & all, I had no problem getting my puppy in and he seemed to like it.

    It didn't work for my puppy

    Too hard to get her in and out. I also underestimated how heavy she would be. 15 lbs was too much weight for me to carry around. I returned it.
