My dog wears a Cabela's vest. She wears it for 2 reasons. 1st sunday trips to the vet to get stitched up due to barb wire fences get expensive really quickly. 2nd it helped make her more visibile in the field. Labs are a popular dog and when you get a few yellows out there running back and forth in the corn it's nice to have the vest on her for easy recognition. I can vouch that that it has definatly saved her from multiple trips to the vet. It's outer shell is torn up/ripped up from her going through stuff. Well worth the investment (which wasn't much) to keep the dog safe
Best picture I could find with her wearing it
