Canny Collar Size 5 black ANTI-PULL DOG COLLAR  Offers a kind, safe, and effective way of stopping dogs on walks. EASY TO FIT  Its as easy as fitting your dogs regular collar. We use a standard, nickel-plated steel buckle and pin fitting for greater security and a simple line of high quality webbing to control your dogs head. SIMPLE TO USE  There are no complicated instructions, just fit it and go! TRAINING NOT RESTRAINING  The Canny Collar can train your dog to walk on a simple collar and lead with no pulling. By moving the slip line on and off your dogs nose as required, you can gradually teach him not to pull at all, even when he feels nothing on his nose. LEAVE IT ON WHEN OFF LEAD  No need to take the Canny Collar off when letting our dog run-free  simply use the carabiner clips to fasten the slip line underneath your dogs chin and away he goes.
