Description

Gentle & kind design: Patented, behind-the-head design prevents riding up into your dog’s eyes or yanking of her neck. Won’t be confused with a muzzle.

Simple to fit & use: Fastens like a regular dog collar. Easy ‘pressure & release’ action gently trains your dog not to pull.

No restrictions: Self-adjusting, soft nose band adjusts to fit the shape of your dog's face so she accepts it easily. Single strap allows her to open her mouth, pant and breathe freely.

Safe for you both: Secure steel buckle won’t snap open. Lead attaches behind the head so your dog cannot paw it off and become loose.

Training, not restraining: Nose band ‘steers’ your dog’s head. Can be slipped off when not needed to train walking on a regular collar and lead.

No need to remove when off lead: Fasten the nose band under your dog’s chin with the included carabiner clips when letting your dog run free.

Suitable for: Large & giant breed dogs with a neck size of 58-69cm such as Newfoundlands, St Bernards, Pyrenean Mountain Dogs.

Please note: The Canny Colossus is an aid to your walking training, not a quick fix.

20% OFF A MATCHING LEAD!: When you add a matching Canny CONNECT Lead or Canny Lead to your Canny Colossus order, you will receive an automatic 20% discount off the price of your lead.

Amazing products

Think this is our 4th Canny collar, due to outgrowing the previous. As a 60kg Newfoundland her safety is my priority, this collar allows me control no matter what.
Love it !!!

Hi Kate, we're thrilled to hear your positive feedback! It's wonderful to know the Canny Colossus is helping keep your Newfoundland safe and comfortable. Thanks for trusting us again, and we appreciate your support!

I've got a 9 month old, 51kg central asian shepherd puppy. He was pulling me everywhere until the canny collar turned up. Took a couple of days for him to get use to it, but now he is a totally different dog. Walks properly and only now and again does he try to pull. Even off the lead, I leave the canny coller on ant tuck the ends under his collar so he thinks it's still on. Wonderful. With a potential weight of over 120kg, and the size of a donkey, I just hope the canny collar will still fit. Thank you so much for a wonderful collar. Made extremely well and worth every penny.

Game Changer

I have a 1 year old, 57Kg Newfoundland "puppy", who to put it mildly was a real handful on a normal collar and lead. Tried a Halti, which was a bit of nightmare as he would just not tolerate it, then came across the Canny Company and thought why not? I am always a bit skeptical of videos showing a dog misbehaving on the lead 1 minute and then in the next shot are miraculously walking calmly along in the next, but credit where credit is due, within a couple of minutes, I could easily hold 57kg of "Newfie" in one hand and have him walk by my side without pulling my shoulder out of its sockets! It does require the owner to be attentive to what the dog is doing as the Nose strap will slip off if you dont keep a small amount of tension on the straps, but would highly recommend to anyone who is having issues with a dog that pulls.

That's fantastic news David, thank you so much for sharing your experience of the Colossus with us. We're delighted that it is helping you both to enjoy your walks with ease (and by keeping your arm in your socket!). We particularly love hearing from Newfie owners as it was a chance discussion with someone from the Newfoundland Breeders Association at Crufts that led to us developing the Colossus. He told us that options for Newfies that pull were very limited so our team went away and designed a version of the Canny Collar that was beefier and sturdier for bigger breeds such as yours. We hope that you both enjoy many more walks together, good luck with your training.

Enjoy stress-free walks with no frustration, embarrassment or fear of being pulled over with our no-pull collar

The Canny Colossus is a comfortable, no-pull dog headcollar designed for large and giant breed dogs that pull on the lead. Unlike traditional headcollars, it fastens behind the head for greater comfort and control, helping you train loose-lead walking safely and effectively.

 

DESIGNED ESPECIALLY FOR GIANT BREEDS

Suitable for giant breed dogs with a neck size of 58 - 69 cm, such as the Newfoundland, St Bernard and Pyrenean Mountain Dog.

 

LESS PULLING, MORE RELAXED WALKS

Helps your large breed dog walk calmly by your side instead of pulling on the lead. Better control, less stress and more enjoyable daily walks.

 

GENTLE TRAINING WITHOUT HARSH CORRECTION

The Canny Colossus works with gentle pressure and immediate release as soon as your dog stops pulling. This helps your dog learn to walk more loosely on the lead, step by step.

 

SECURE FIT THAT WON'T RIDE INTO THE EYES

The lead attaches behind the head, ensuring the headcollar stays securely in place. Doesn't ride into your dog's eyes nor jerk their head to the side.

 

COMFORTABLE FOR YOUR DOG

The soft noseband allows for free breathing, panting, and drinking. The padded collar sits comfortably on the top of the neck and is adjustable like a regular collar.

 

SAFETY AND CONTROL ON THE GO

Stays securely fastened, even if your dog tries to slip the noseband loop off. Ideal for everyday walks, lead training, and large breed dogs that pull strongly.

 

Special offer: Get 20% discount off a Canny Lead!

When you add a matching Canny Lead or Canny Connect Lead to your Canny Colossus order, you will receive an automatic 20% discount off the price of your lead.
