Questions we get asked... often.
Biothane strength, sizing, harnesses, long lines, engraving, shipping: everything you need to know before choosing your dog's gear, straight up. Biothane 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. 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. 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. 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. 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. 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. 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. 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 Sizing, harnesses, long lines, puppies, small or big dogs: we'll help you choose. Always measure your dog: weight and breed aren't enough. Not sure? Write to us before you buy, we love to help. 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. 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. 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. 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. Waterproof, it holds neither mud nor odours. It isn't a pulling harness: it's made for walks and adventures. It depends on your goal: Always attach the long line to a harness, never to a collar. A long line helps training but doesn't replace recall practice. 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. 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. 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. 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. 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. 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 Engraving, shipping, returns and guarantee. Yes.
