Please be sure to double check your pup's collar size! Ensuring size is the responsibility of the buyer and we do not accept returns or exchanges on products where the wrong size is selected. To properly measure your dog's neck, use a fabric tape measure and wrap it around where your dog's collar properly sits. Make sure it is a snug but comfortable fit with no overlap. For martingales, people usually make sure their dog's neck measurement minus one inch is within the collar's range.
