Our dog Ziggy loves the bed. Plenty of room, nice and fluffy! Seems well made. No complaints from us or from him!

Color Block puffer jacket fits perfect. communication was great in terms of shipping. My dog is medium but the x- large fits her perfectly. The coat is warm and she evengot the zoomies after I put it on her.
Grabbed two for our golden boys. Size large for both. One is currently 25lbs and the other is 33lbs. Large fit both nicely and the smaller has a little room to grow while still wearing it. Soft and just as pictured.
Our pup loves her new harness and it fits her like a glove!!
My dog hasn’t left it. He loves this bed. Fluffy, cozy and aesthetic for me!
So soft, plush and comfy for our golden boy. We ordered a size large for a 40lb mini golden doodle. I was concerned because it's hard to size him since he's stocky, but it adjusted so well and allowed us to have a perfect fit. Will be great in winter when he wears heavier clothes or we can tighten when he gets shorter hair cuts. Love the versatility and color was exactly as described.
This is the only front lead harness I was able to find for my 10.5 lb Cavapoo. It has made a big, positive change in our daily walks. The Park Ave Pink is a real head turner; it’s become Sadie’s signature color!
Awesome backback.Got the dogs ridingstreet bikes with me. They have ridden the ZRX1200 and the dual sport thanks to the K9 Sport Sack!
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.
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
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!
My dog loves it so much. This harness is comfy on her and gets compliments.
