Sizing was off

My frenchie has a small harness and out grew it so I ordered this one in a medium and it fit him just like the small so I’m currently exchanging it for a large. Hopefully it fits. I love the quality of these harnesses and as long as my guy doesn’t outgrow the brand completely I’ll be a customer for life.

We Love This Harness!

Our Frenchie is very compact at 33lbs. It was hard to find a harness that is short enough, but big enough to go around her chest. These harnesses fit her perfectly! We got this design for a puppy that we are getting soon. I have no doubt it will fit him just right. I also love the patterns!
