10 out of 10

The backpack with the portable "kennel" is a dream come through! It served its purpose well beyond my expectation and I highly recommend it! It's collapsible for ease of storage when not in use. It's well ventilated to allow my dog to feel comfortable and safe. The build quality is superb. The only nuisance is that it's hard to remove the protective film from the plastic windows BUT that's such a small price to pay and at least guarantees that my backpack will arrive with no scratches. I LOVE IT.
