Tag-a-longs are designed to buckle around the collar to hold the dog's ID tags. This makes moving ID tags from one collar to another a simple task! Simply un-buckle the tag-a-long and buckle it to around the new collar!
Does your dog stay with a doggie sitter on a regular basis? Creat a pet ID tag with the contact information of the doggie sitter and keep it on a tag-a-long. Then you can simply clip it to the collar when your dog is at the sitter!
