Biothane strength, sizing, harnesses, long lines, engraving, shipping: everything you need to know before choosing your dog's gear, straight up.

Biothane

Strong, clean, built for outdoors.

Everything you need to know about the material in our collars, leashes, long lines and harnesses.

Can't find your answer? Email us at info@creationstanzo.com or call 514 552-5742. A real person will answer.

Is Biothane really strong? How strong is it?

Yes. According to the manufacturer, the Biothane we use has a linear strength of about 1,000 lb at 1 in. wide and 500 lb at 1/2 in. Even a big dog pulling hard only puts a fraction of that force on it during a walk.

On a collar or leash, what breaks first is the hardware: a snap hook, a buckle or a ring. That's why we choose sturdy hardware and assemble our pieces with rivets.

Is Biothane stronger than nylon?

In real life, yes. Biothane doesn't soak up water, doesn't fray and doesn't lose strength with moisture, freezing or salt.

Nylon absorbs water, gets heavy, holds odours, wears down from friction and stiffens in winter. That wear is what makes a collar or leash less safe over time.

Does Biothane hold up to water, odours, salt and Canadian winters?

Yes. It's waterproof, holds no odour, doesn't absorb slush, mud or salt, and stays flexible even in deep cold. It doesn't mould or stick to fur. A rinse and a paper towel are all it takes.

How do I clean and care for a Biothane collar or leash?

Rinse with lukewarm water, add a little mild soap if it's very dirty, then wipe dry. It's clean in seconds, even after mud or slush.

For long lines, undo knots right away: a knot left under tension for a long time can become impossible to untie. And keep your gear away from teeth: it isn't a toy.

Is Biothane chew-proof?

No, and no material is. Nylon, leather or Biothane: a dog who chews their gear will eventually damage it. That's actually by design: a trapped dog needs to be able to chew through their leash to free themselves if their life is in danger.

Chewing is a behaviour to work on. Damage caused by teeth isn't covered by the guarantee.

Is a thicker Heavy Duty collar stronger than Standard?

No, that's a myth. Standard and Heavy Duty Biothane have the same internal strength: Heavy Duty is just thicker and stiffer.

Standard is right for 99% of family dogs. We'll never sell you a pricier product just because it looks stronger.

Why do you use rivets instead of Chicago screws?

For safety. Chicago screws can work loose over time from movement and friction. Our rivets are set with calibrated pressure, never come loose and need no maintenance.

Choosing

The right gear for your dog.

Sizing, harnesses, long lines, puppies, small or big dogs: we'll help you choose.

What size collar or harness should I choose for my dog?

Always measure your dog: weight and breed aren't enough.

  • Collar: measure around the neck where the collar will sit. You should be able to slide two fingers between the collar and the neck.
  • Harness: you need three measurements: chest girth, shoulder clearance (from the chest to the withers, on one side only) and the belly strap (from the front of the chest to the chest). See the harness size chart.

Not sure? Write to us before you buy, we love to help.

Collar or harness: which should I choose?

A collar is ideal for carrying ID tags and for dogs who walk well on leash. A harness is better for a dog who pulls and for long lines: always attach a long line to a harness, never to a collar.

To compare our clip and belt buckle collars, see our guide to choosing a collar.

What does Québec law say about leashes and harnesses?

In Québec, in a public place, a leash must be no longer than 1.85 m, and a dog weighing 20 kg or more must have its leash attached to a harness or head collar. Your municipality may have its own rules too.

Long lines are for places where they're allowed. Source: Gouvernement du Québec.

What's the best dog leash?

Our honest answer: the 5-in-1 Biothane leash. Short in the city, long at the park, around your waist for hands-free walks, across the body on trails or tied up at a patio: one leash does it all.

It's waterproof, cleans in seconds and comes with its Tanzo Academy how-to lesson.

Which harness is best for an active dog who loves the outdoors?

The Tanzo Y-harness. It goes around the shoulder blades to keep the shoulders free, doesn't rub under the legs and stays stable when your dog runs or shakes off.

  • Back attachment: for everyday walks.
  • Front attachment: to support, not replace, leash training.

Waterproof, it holds neither mud nor odours. It isn't a pulling harness: it's made for walks and adventures.

Which long line should I choose?

It depends on your goal:

  • Waterproof long line (20, 30, 50 or 60 ft, with handle): to explore, sniff and enjoy controlled freedom.
  • Recall long line (38.5 ft, no handle so it won't snag on the ground): to practise recall at a distance.

Always attach the long line to a harness, never to a collar. A long line helps training but doesn't replace recall practice.

What gear should I buy for a puppy?

The essentials: a light collar, a short leash for outings and a long line to explore and learn recall safely. A harness is recommended too, but if you have to choose, the long line comes first.

See our puppy essentials. And don't forget treats: positive reinforcement helps a puppy progress more than any gear.

Are your products suitable for small dogs like Chihuahuas?

Yes. For toy breeds (Chihuahua, Pomeranian, Yorkshire terrier), we recommend a clip collar, lighter around the neck, in Standard Biothane: the same strength, without the weight. See our small dog collection.

Are your collars and harnesses suitable for big dogs or dogs who pull?

Yes for walks, trails and life outdoors. For a strong dog, we recommend the belt buckle collar, with its metal buckle that can't open by accident.

Our products aren't made for pulling sports, weight pulling or bite work. And no gear teaches a dog to stop pulling: that comes with practice.

Are your products suitable for reactive, anxious or excitable dogs?

Yes, in most cases. We recommend the belt buckle collar, safer during sudden movements, with a leash suited to your level of control.

Every dog is different: the guardian remains responsible for fitting and using the gear. If your dog worries you, a dog trainer is your best resource, and we can refer you to a professional.

Who is the martingale collar for?

For dogs who back out of their collar, like some sighthounds or fearful dogs. The martingale collar tightens slightly so it can't slip over the head. For most dogs, a clip or belt buckle collar works very well.

Will a harness or leash stop my dog from pulling?

No. No tool stops a dog from pulling by magic. Good gear makes walks safer and more enjoyable, but real progress comes from positive reinforcement, consistency and practice.

To help, the Tanzo Academy offers practical lessons, and we can refer you to a dog trainer.

Ordering

Order with peace of mind.

Engraving, shipping, returns and guarantee.

Can I have my dog's name engraved on the collar?

Yes. Laser engraving is available on all our Biothane collars: add your dog's name (+$5.99) and your phone number (+$4.99) when you order. For a sale collar, write to us first to check if it's possible. Fabric collars can't be engraved.

How long will my order take to arrive?

Orders are prepared in our Mascouche workshop within 24 to 48 business hours. Then allow 2 to 5 business days in Québec and Ontario. Shipping is free on orders of $110 or more before taxes, anywhere in Canada.

Do you ship sustainably?

Yes. Close to home, we deliver by electric car and bike, right to your mailbox. You can also choose a reusable PickPack package: send it back and get a $5 credit on your next order.

Can I pick up my order in person?

Yes, local pickup in Mascouche is available by appointment.

What if the size doesn't fit?

Write to us within 7 days of delivery. The item must be new, unworn and with its tag. Fees may apply depending on the situation: all the details are in our return policy. Clearance, engraved and personalized items are final sale.

What does the Tanzo Guarantee cover?
