The brand is Arcadia Trail. I just picked this up but it is a little too small around the girth for my dog ( my dogs measurements are: height to top of shoulders 24" length from front of chest to base of tail 29" and her girth is 31" she is a lean athletic 86# dog. There's no size tag on this jacket but overall it needed to be 2" larger in all three of the dimensions I've listed for my dog to fit it comfortably. I think its best to bring the dog to try it on before purchasing.
