Martingale collars are particularly suited to dogs that have heads smaller than their necks, e.g. greyhounds, whippets, or borzois but are a fantastic design for any doggo. Martingale collars are not for constant wear - they are for leash walking only as the very attribute that makes them secure (tightening when pulled) presents a choking hazard should your doggo become caught up on something.
