FAQs

Good question. We're about to let you in on a secret... Are you ready? Good! So each harness size can actually get bigger or smaller than the limits showed above.

Here are the maximum and minimum measures for each size.

That's great news! It means you can go with either sizes and you can't be wrong... They should both fit! But here's how we suggest you handle this tie:

1. Go with the weight. Here's how we suggest a size based on weight.


2. Check the breed fits below
for a dog breed with similar shape and weight as your pup. By comparing what those breeds are rocking, you can find the fit that you prefer.

We understand these things can happen, but we try to avoid it as much as possible. It will save both of us a lot of headaches about returning the harness and sending another one your way. If you need to exchange the size, you will have to cover the cost to return it and we will cover the cost to send you a new one.

*If you're unsure about the size you should select, use the question below to get help with sizing.

Are you sure? You went through the quiz above, you checked the charts and everything? And still, you are not sure about the size you need? If so, get help with sizing.
