**UPDATE** I was wrong. Customer Service (Sheila) contacted me w/in an hour after posting this review. Sheila was professional and extremely helpful. We went back and forth w/measurements and I am trying the next size up for fit. If you have a dog w/a deeper chest and have questions about fit, just give them a call first. They will happily help prior to ordering! -Purchased an XL for a Rottweiler. Back length is perfect; girth strap is easily 6-8" too short. Company offers no solution but to have a seamstress 'make me one that fits'. Customer Service said "we've had this issue before..." Don't purchase if you have a dog that's not 'houndy'. Will not fit anything w/a deeper chest.
