This question is for all those Boxer owners who have a full grown Boxer. I'm trying to find out how many inches long your Boxer's collar is. I realize all Boxers varry in size, but I was wondering if maybe there's any size that stands out. The breeder told me Blaize would probably get to 70 pounds. I'm asking because I'm wanting to purchase an expensive collar, but one that he can wear as a full grown dog. Any feedback is appreciated. Thanks!
