Heavy Duty Training Collars are a totally secure Training Collar for very strong or heavy pulling dogs. The buckle has been removed and the tightening loop opens to easily fit the collar over a dog's head.

Careful consideration to design, construction and choice of materials has enabled us to produce a highly effective Training Collar that is robust and looks great.

• Adjustable - to exactly and comfortably fit a dog's neck, and can be adjusted as your dog grows
• Extremely easy and safe to use
• Simple to fit
• Unique "Designer Dog Wear" appeal backed with Black Dog's quality guarantee
• Will not over tighten on a dog's neck - the cause of nasty K-9 throat & neck injuries
• Will not Cut, Mark or Remove a dog's coat
