Picking a cusom collar will come with a clean slate, and you can pick and choose what your collar will say or have displayed on it. Custom collars are useful for working dogs, or dogs that may not be as social. (Ie, WORKING DOG, DO NOT PET, GIVE ME SPACE) All Collars are madeout of a military grade nylon material made here in the USA, they are waterproof, mud proof, and beach approved! When choosing the lettering for your collar, choose a main base color then if you have several different words for example “Saint” “working” “Do not pet” when writing what you want in the box, put the color in parenthesis next to the word so it will look like this : Saint (White) Working (yellow) Do not pet (digital camo) We usually recommend to get the mesh lining if you have a bulkier built dog, or if you do dog sports or have a lot of flat leash pressure, mesh is sewed into the interior or the collar to help prevent harsh direct pressure on the leash and prevents choking. If you have a lighter built dog we usually recommend opting out of the mesh lining as it can give a bulky look.
