From Leather Brothers we have a pair of durable, oil-tanned 1 inch-wide leather bully collars with heavy-duty nickel-plated hardware. Bully leather is the toughest leather on the market. They get very high marks from owners for wearability and durability. Those owners confirm that the leather just gets softer and more comfortable as time goes by. Some owners say they have used their bully collar for five years, and it's still going strong. You have a choice of a two-row cone stud style, or single-row oblong studs in a lovely saddle brown. Highly recommended for the larger dog.
These collars come in a range of three sizes, all 1-inch wide
Once you have measured your dog's neck, add 4" to determine the correct collar size.
MEASURING FOR A COLLAR
Before deciding the size, please take a moment to measure your dog's neck, using a cloth measuring tape or string, twine, etc. Measure, wrapping the tape or string about as tightly as the collar should sit on your dog's neck--not too tight. If using string, then hold the final length up to a ruler or yardstick to determine its length. If in doubt, go to the next larger size--you can always adjust a collar that is slightly too big, not so much with a collar that's too small. This will help prevent an exchange, which just wrecks everyone's day! : )
