Need some help. I'm looking for a camo vest for my yellow(got alot of white on him) lab. This vest doesn't really need to be for floatation. I just want it to cover up some of that white in the dove field. Only problem is my lab is already at 70-75 lbs. and will be 8 months old this month. I was going to just go ahead and buy him the largest size from Cabelas(3X) but I read where one guy said he had a 100lb. dog and it was too small. I know my dog will be well over 100 when he's full grown. I guess I could buy the 3X for this season and then try to find a larger one next year????? Do any of yall know where I might find a good vest that offers BIG sizes????? Thanks!
