Bests & Worsts Reviews from Amazon

I originally ordered an XL for my 70 lb Lab based upon user reviews noting the jacket runs small. The XL swallowed my dog so will not fit. I ordered a L, which says up to 85 lbs and it is so small it will not fit my 70 lb dog. The size difference between the two is unbelievable and both are supposed to fit an 85 lb. dog (L up to 85 l S and XL starting at 85 lbs.)
