Train your large breed dog to stop pulling on lead

The Canny Colossus is the best collar to stop large breed dogs from pulling on the lead, transforming even the worst pullers into happy, well-behaved pets.

Voted ‘Best New Product’ by the UK pet industry when first launched, the Canny Colossus is simple to fit, easy to use, kind, safe, comfortable and effective.

Suitable if your dog's neck measures more than 58cm. Example breeds: Neapolitan Mastiff, St Bernard, Pyrenean Mountain Dog.

  • Collar - 38mm wide
  • Slip line (nose band) - 20mm wide


Unique design

Our unique, patented ‘behind-the-head’ design means the Canny Colossus does not ride up into your dog’s eyes nor yank her head to one side, both of which will cause her distress, discomfort and which could damage her neck.


Trains your dog to walk on a regular collar

Can be used in both ‘training collar mode’ and ‘regular collar mode’ by easily dropping the slip line (nose band) off your dog's nose as needed. This way, you can train your dog to eventually walk on a regular collar and lead.


A comfortable fit

The slip line over your dog’s nose is soft, strong and adjusts easily to fit the shape of your dog’s face. As it is only one light piece of webbing, your dog is able to breathe easily, pant and even carry a ball or toy in her mouth. Because of this, it will never be confused with a muzzle when meeting other dog owners.

The collar that fits around the neck is made from high quality, padded, cushioned webbing which is both strong and comfortable. When your dog is happy she will be much more receptive to training.


Total control

Your lead attaches to the D rings on the slip line. This works independently of the collar, giving you a direct connection to your dog’s ‘steering’.

The slip line eliminates pulling and lunging by applying gentle pressure when your dog pulls and immediately releasing the pressure as your dog stops. The collar part stays in a fixed position, just like your dog’s regular collar.


Safe & secure

Because the Canny Colossus fastens behind the head and not under the chin, your dog cannot lift her paw over her lead and pull the collar off her head. Even if she manages to get a claw into the slip line and pull it off her nose, your lead is still secured to the D rings and so she cannot escape.

The nickel-plated steel buckle provides added reassurance and ensures a secure fastening that will never snap free. This means your dog is always safe, avoiding any potential danger for both of you.


Superior quality workmanship and top value

Your dog deserves the very best! The top quality padded collar, soft yet strong generous slip line over the nose and nickel-plated steel buckle and fittings mean the Canny Colossus is the very best value for money:

  • Combines safety, comfort, superior quality materials, fittings and workmanship
  • Provides complete but gentle control
  • Does not ride into eyes
  • Does not yank your dog’s head to one side - recommended by chiropractors
  • Recommended by dog trainers, training schools, rescue shelters and veterinarians worldwide
  • Wipeable and washable material is easy to keep clean

If you are embarrassed by your pulling dog, dread taking your dog for a walk and have tried everything else to stop your dog pulling on lead, then the Canny Colossus is the answer. Available in black.

What if I order the wrong size Canny Collar?

No problem. Providing you purchased the collar from our European website and return it to us within 7 days in a new and resaleable condition, we will exchange it for you. Simply return your collar to us along with a printout of this form and we'll do the rest.


How do the sizings work on the Canny Collar?

Since dogs, like humans, come in all shapes and sizes, it’s important to measure your dog's neck snugly to ensure you have the correct size Canny Collar. As your dog's neck can sometimes be hard to measure accurately (especially if there is a lot of fur), we have designed the Canny Collar so that each size overlaps with the sizes above and below, so there is some flexibility when choosing your size.

Once you have your collar fitted, it's advisable to test first in your garden or house to ensure it cannot come off over her head.


What if my dog is exactly between two sizes?

If your dog is exactly borderline between two sizes, we generally recommend getting the smaller size of the two options. If you have a puppy however, it may be worth waiting a month or so and buying the larger size.
