Excellent for dogs which easily slip a collar (i.e. Greyhounds, Dachshunds, etc.). The unique Limited closure prevents the collar from becoming too tight. This adjustable collar is made from high quality nylon that is thick, strong, and specially processed to prevent fraying. All nylon products are carefully and neatly finished for the best look and durability. The small No Slip 5/8" width collars are adjustable (10" - 14"). The medium No Slip 3/4" width collars are adjustable (14" - 20"). The large No Slip 1" width collars are adjustable (17" - 24"). Available in black or pink.
