Train your large breed dog to stop pulling on leash
The Canny Colossus is the best collar to stop large breed dogs from pulling on the leash, 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 23". Example breeds: Neapolitan Mastiff, St Bernard, Pyrenean Mountain Dog.
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 leash.
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.
Your leash 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 lungeing 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 leash 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 leash 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:

Measure your dog’s neck
To ensure your Canny Colossus or Canny Collar fits accurately and is safe to use when walking your dog, take a tape and measure around your dog's neck snugly, to just behind the ears. Then, choose the correct size for your dog using the following measurements.
If your dog's neck measurement falls exactly between two sizes, our experience shows that the best option is normally to choose the smaller of the two sizes to ensure a good fit.
|9" - 11"
|11" - 13"
|13" - 15"
|15" - 17"
|17" - 19"
|19" - 21"
|21" - 23"
|23" - 27"

Fitting & using the Canny Colossus
Fasten the Canny Colossus around your dog's neck, ensuring the buckle is positioned just behind his ears at the back. Fold any excess collar and tuck it under the lip of the buckle. The Canny Colossus should fit higher up the neck than a conventional collar, as shown.
A snug fit is essential with any dog training collar to ensure that it cannot come off your dog whilst walking. Test the Canny Colossus by trying to pull it off your dog's head whilst facing him - if fitted correctly, this should not be possible.
Pull each end of the thin slip line behind your dog's head and attach your leash to both 'D' rings at each end.
Pull the slip line through the small yellow plastic guider at the front of the Canny Colossus and place over your dog's snout. With some breeds, it may be easier to do this before attaching the leash. Take care not to twist the slip line before placing it over your dog's snout.
Ensure you leave the plastic guider under your dog's chin. This is absolutely vital. If this plastic guider is not kept under the chin, the Canny Colossus will not function correctly.
When your dog starts pulling on the leash, apply gentle backward pressure. Instant release of the pressure occurs when he stops pulling. This pressure and release system is the key to using your Canny Colossus correctly as your dog trains himself to stop pulling.
When letting your dog off leash, the Canny Colossus can be left on him by removing the slip line from his snout and pulling it out fully. Cross the slip line behind his head and drop it either side of his head as shown.
Bring the D rings together to meet underneath his chin and use one or two of the optional carabiner clips to secure the D rings together.
When walking your dog, your leash should be kept short but loose so you can control him quickly and easily. An extendable or long leash is not recommended for use with the Canny Colossus as the slip line may not remain in place on your dog's snout.
Walking with a Canny Colossus
Put the Canny Colossus on and go for a walk immediately. Keep your leash short but loose when walking and aim to have your dog in the 'heel' position. Using a shorter leash will make this easier, around 4 ft length is ideal. Give him plenty of vocal praise when he begins walking well.
The first time you put the slip line over your dog's nose, he may resist it and try to paw it off his face. Any head halter will cause this reaction for some dogs. It is similar to the feeling we have when wearing a wristwatch for the first time - some dogs are simply not used to it. If your dog reacts this why, try desensitizing him first by introducing the collar slowly, then building up to going for a walk.
You should continue walking so that your dog focuses on the walk rather than on the Canny Colossus, lifting your leash when he paws at it and verbally encouraging him to follow you.
When you first start walking with the Canny Colossus and getting your dog used to wearing it, you will have to pay attention to him during the first few minutes to make sure he is keeping his head upright, that the Canny Colossus is loose around the mouth area and that the leash is long enough to be loose but short enough so that the slip line does not move towards the front of his nose and fall off.
These first couple of minutes are an opportunity to connect with your dog and be focused on training him to walk well. The first five or ten minutes are the most important part of the walk for both of you and if you can get your dog walking well in this time, the rest of the walk will be a breeze.
Keep your leash loose when walking
Once your dog is walking, instantly lower the leash to release the pressure on the Canny Colossus (you should also let him have some more leash here) and give him plenty of vocal praise whilst keeping walking. He needs to know that at some point in the walk, the pressure will be released; otherwise he may just continue to pull against it.
Repeat this action if again he tries to remove the Canny Colossus. Because the leash is connected behind his head, he will not be able to get a paw over it and bring the walk to a stop. Nor will he get the Canny Colossus off his head if the leash is kept in the correct position. Sometimes you may need to let the leash out if he drops behind you, bringing it back in again once he catches up.
Once any initial resistance to the Canny Colossus has stopped, continue walking your dog for a short distance and then stop and give him plenty of praise.
Use treats or clicker training if your dog responds well to these to accustom him to the Canny Colossus.
