This is a specific conversation about Dog collars — fit, material and safety — ask about yours and get one honest answer for your exact situation.

Collar fit and safety matter more than most people realise — too loose and a dog can slip free, too tight and you risk injury, and some breeds genuinely need specific collar types to stay safe and comfortable. A Dogo Argentino is a powerful, muscular dog, so getting this right is especially important. What size is your dog, is this collar for everyday ID wear or will you be using it for training too, and are there any specific concerns you've got in mind?
He's 4 years old, about 40kg, very strong puller on the lead. This is mainly for everyday wear and ID tags. My main concern is that he's pure white and every collar I've tried so far has left colour staining on his fur around his neck. It's really noticeable and takes ages to wash out.

That's a really common problem with white-coated dogs and it's genuinely frustrating — dyed leather and cheap nylon are the worst offenders because the dye bleeds, especially when wet from rain or swimming. Before I point you toward something specific, a couple of quick questions: what's his neck measurement, and does he swim or get wet regularly? That'll help me confirm the best material.
His neck is about 55cm. And yes, he swims quite a bit in summer — we live near a river. So it needs to hold up when wet.

Perfect, that's exactly what I needed to know. For a white-coated dog who swims and has a strong neck, I'd go straight to a BioThane collar. BioThane is a coated webbing material — it looks and feels similar to leather but is completely waterproof, doesn't absorb dye, doesn't rot, and crucially won't bleed colour onto fur even after repeated soaking. For your dog I'd specifically recommend the Logical Leather Personalized BioThane Dog Collar — it comes in a plain white or light grey option, has a solid stainless steel buckle that won't rust, and at 55cm neck size you'd be looking at a large. It's also wide enough at 2.5cm to sit comfortably on a big dog without digging in. The surface wipes completely clean, so any mud or river water just rinses off without the material holding onto anything.
That sounds really good actually. Will the white BioThane itself stay white though, or will it go grey and grubby over time?

It holds up well — because the surface is non-porous, dirt sits on top rather than soaking in, so a quick wipe or rinse keeps it looking clean. It won't yellow the way nylon does. The only thing I'd say is avoid any collar with metal hardware that isn't stainless steel or brass, because cheaper zinc alloy buckles can leave a faint rust mark on pale fur over time. The collar I mentioned uses stainless hardware specifically, so you're covered on that front. One last thing worth checking: at 40kg and pulling on the lead, make sure you're measuring his neck with two fingers of slack — a large in most BioThane collars should land right for 55cm, but always verify before you order.
Great, that's really helpful. I'll go with that. Thanks.

Good choice — it should genuinely solve the staining problem. Just double-check the fit when it arrives: you want two fingers of slack, no more. Given how strong Dogos are, a snug, secure fit matters as much as the material. Enjoy the river walks.
