Awesome backback.Got the dogs ridingstreet bikes with me. They have ridden the ZRX1200 and the dual sport thanks to the K9 Sport Sack!
I have a 9lb toy Aussiedoodle, ordered the size small and it's PERFECT for her! Can't wait for camping/hiking trips this summer, where I know she'll get tired and want a ride
Perfect for my pup's first hikes. Light and comfy.
Living in the city, it's great to have a carrier that lets me take Max, my Dachshund, around comfortably. He loves the view from up here!
Took Bella, my adventurous Beagle, on a mountain trail using this carrier. The internal frame and hip belt provided excellent support, and she seemed comfortable throughout.

We ordered a XS size frenchie brand harness. We are happy with a harness made to suit the breed’s specific needs (even if it’s just for practice right now, since she’s still a puppy)!
Wuforia ordering process was easy, they communicated with me, and shipping was extremely quick! Do plan to purchase another harness as she grows.
Great quality, beautiful colors, arrived quickly, too. My girl is stylish & comfortable in it.

My pup, Selah, is a pretty specific fit. Neck and chest are large, small waist (50% American staffordshire terrier, equal split on boxer, golden and lab mix). She's @70 lbs and ordered the 2XL and it fits unbelievably awesome. Aside from that, the style is fashionable sexy/sporty, just like her mom 🤩. I LOVE this jacket and how it fits, and I think Selah might actually love wearing it! 5 stars for quality, for, style and Exceptional customer service (thank you Rhylee!)
I got this as a present for my friend who loves TMNT, he absolutely LOVES IT! It's so simple to use and the size is perfect, you can adjust it according to your dogs size and there's a lot of room to make it smaller or larger. I got a large for a 70 pound doodle and it fit perfectly!
Just as pictured! Love it and saved $
Great quality just as advertised super good grippy suction cups LOVE!
Soooo cute exactly like the picture
Cuddly and soft! Arrived in a timely manner.
Cute pattern and great quality!
Perfect for my pup's first hikes. Light and comfy.
Rosie (my Pom) looks like an absolute doll in this.
My golden retriever looks like a catalog model in this sweater.
Fits my Frenchie great. He stays warm and gets compliments.
