margo has severe hip arthritis but still enjoys being part of our hikes, this allows her to still join and take a rest in the pack as needed or in steep areas

Great Pack - Didn't need tornado...

Mabel loved her first bike ride in her K9 Rover 2. She sported beautiful pink goggles and loved the wind rushing bye. However... on that first ride we spotted a tornado near the house! That meant old me needed to peddle even faster to get in the basement! Luckily no major damage but in the future, please keep shipments to packs, patches, and puppy toys only. Thanks!

BEST Backpack for Doggos on the market!

We love K9SPORTSACK so much that this is actually our third backpack from them - the 2021 new model ROVER 2. We previously had the original ROVER and loved it so much we had to give the new model a shot as well!

The ROVER 2 definitely has upgraded to an even more sturdy backpack with more support for the back and more adjustable options such as the shoulder strap height and and the distance your pup is from your neck/head area depending on your size. What we love most about this backpack is the feature to now just use it as a hiking backpack or (throw all your belongings out and carry the dog instead) cause you know, no dog gets left behind! :)

Our only comment to note for anyone who is upgrading from the ROVER to the ROVER 2 is that the new ROVER 2 is a little bit longer than the original Rover so depending on how your dog fits in it, you may need a booster block. POPEYE fits in the original Rover perfectly with no booster but with the new ROVER 2 he needs a teeny boost (with a folded towel) and he's golden!

It's definitely the best backpack out there to carry your dog in for all kinds of adventures especially those pups who can't walk long distances and/or disabled! We LOVE this backpack and would highly recommend - you won't be disappointed!

Great idea...I got a big dog

It works well walking around. However, I hoped on a scooter, and she gets a bit skiddish at 40mph... once she hits or passes 80lb(50 now), might be just for walking around. Great product for sure

Perfect for when the pup gets tired out!

The Rover 2 allows me to still go on nice long hikes with my 3-month-old golden retriever. He walks for a bit and when he tires out, I put him in the pack and off we go.
