Bought the Trainer sack as a starter for my 15 year old westie Daisy. Bought a size medium and it was a perfect fit. So happy to be able to bring her along for the long walks again. Had been looking for the perfect carrier for a while now and finally found a company that make great carriers. Natasha- Ireland

Bought the large with a booster block for our Shiba puppy. It's a little large for him but with the booster block and the straps it's adjustable enough that he's comfortable in it. This is a great starter bag because of its price - I will likely go for one of the fancier versions once our Shiba is fully grown.

We love love love our k9 sports sack! It is perfect for our puppy when we go hiking. She loves it because she feels secure and can see everything. I love it because she is safe and can’t get out.

We ordered this for our new rescue lab puppy who is a tripawd. He had a badly broken leg amputated by the rescue. We were looking for something to spell him during longer walks and hikes. We do lots of hiking with our other dogs and it was important to us that he be able to participate too but being careful with his joints. This is where we found K9 sport Sack and their line of products. We chose the trainer as he is a growing pup. Being a lab, he is sure to outgrow it in due course, but we will move into the Rover for sure! Great product and keeps the pup very secure and him in reach to give him treats along the way!

Bought online, had it shipped from the US to Australia, Item was quickly dispatched. I was impressed by the quality of the materials and stitching used. Our "Scruffy" is a Toy Cavoodle, 4.5KG, 42cm length so we selected the Plus2 in Size Small. Which is a perfect fit for him. He loves it, and when the pack is on the floor he walks up, sits on it wanting to hope in. Great for walks and bike riding.
