Order larger than the chart says. I ordered a medium, which has always fit my dog, but had to send it back and get a large.

This fit my boy just fine - true to size - and looks snazzy! I cannot speak to durability because I've only had it a short time and do not use it every day, but it seems very well made.

Very sturdy and good looking. Will buy another when it comes time.

If you have flat nosed dogs these harneses work great. This particular harness is for my boston terrier & she hasn't slipped it at all. I gave comfort a 5 but of course I'm not wearing it but Gigi isn't complaining and actually helps me put it on her so must be comfortable.
The colors are great and reflect some at night too

Absolutely love the colors and pattern of this harness! Ive had so many compliments! Its so hard finding cute boy harnesses but this is by far the best!! Ive bought several from this brand and they all have been very durable and last forever! Easy to clean, just throw in the washer with like colors and hang to dry!
