Great!

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.

Best investment!!!

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

Epic!

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!)

Perfect for the doodle

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!
