Abstract: A pet collar has an adjustable length strap and a buckle. The buckle has a receiver and a clip releasably coupled to the receiver. The receiver includes a catch portion coupleable to the clip and a tension indicator portion. The tension indicator portion has two side walls defining a shuttle channel. Each side wall has a top surface having a first mark, a second mark, a third mark, and a fourth mark which have color coding. The shuttle channel is configured to slidably receive a reciprocating tensioning shuttle therein. The tensioning shuttle includes two side wall and a compression spring. Each side wall also includes a top flange overlaying the receiver side walls that includes a first viewing window and a second viewing window. The viewing windows alignment with the underlying marks indicated the tension of the collar upon the pet.
