i know that dogs are different sizes but what are your males neck sizes?? im just curious because i want to get a collar that will fit now and then be able to adjust as he grows. he's been wearing the one he has now since he was 3.5 months old and now that he's closeing in on 6 months he's about to outgrow it.
Bison makes some really nice adjustable collars (BisonDesigns.com) the large goes from 20-32", the medium 15-24". My slim female takes the medium, my LC and stocky male takes the large. It's always fun to swap out collars on occasion though.
