They were muzzled lymers, […] scent trackers with fringed dewlaps and busy, intrusive noses.
– Jame's narration, To Ride a Rathorn, "Chapter XIII: Blood and Ivory", I
The lymer is a breed of scent-tracking dog bred and used by the Kencyrath. They are frequently kept muzzled when used. Different lymers are described as white and black, so there is color variation among the breed.
