Best collar for swimming Weimaraner

Biothane has a great reputation for water resistance, but peaty river water is a real edge case — the tannins in peat can stain and discolour certain materials permanently, which is frustrating when you've invested in what's supposed to be a waterproof collar. Collar fit and safety features matter more than most people realise too — too loose and a dog like a Weimaraner can back out of it, too tight causes real discomfort, and active breeds often benefit from specific collar types suited to their build and lifestyle. So before I suggest anything: is your Weimaraner a typical male or female build, roughly what neck size are we working with, and is this collar purely for ID and everyday wear or does he or she swim regularly enough that durability against peat and river water is the main priority?

That's a well-known problem with the Exe on Exmoor — the peat content is very high and it absolutely punishes certain materials. Biothane is PVC-coated, and while it repels plain water well, the peat tannins get into the surface coating over time, especially at the stitching and buckle edges where the coating is thinner. For a lean-necked, high-activity female Weimaraner who's in peaty water weekly, I'd move away from biothane entirely. What's her temperament like off-lead — does she pull hard, or is she mostly running free? And does she wear a tag on the collar, or is she chipped and tagged separately?

Perfect — that makes things straightforward. For a dog like yours I'd go with the Ruffwear Confluence Collar. It's built specifically for water dogs: the webbing is a polyester-nylon blend that doesn't absorb water or tannins the way biothane's coating does, the hardware is fully stainless steel so there's no rust and no staining from contact with peaty water, and crucially it has a welded aluminium V-ring for the ID tag that won't corrode or discolour. For a female Weimaraner at 40cm you'd be in their medium size. After a peat swim you can just rinse it under the tap and it comes up clean — there's no coating to stain because the material itself is inert to tannins. It's not the cheapest collar, but given how often she's in the water it will outlast anything with a surface coating. I'd size carefully — measure snugly and go by their size chart rather than defaulting to medium without checking, as Weimaraner necks can sit at the upper end of a size.

It's genuinely designed for everyday wear — Ruffwear build their collars to be left on full-time on working and active dogs, so the buckle is a reinforced side-release that's robust without being fiddly. It's not a clip you'd worry about popping open. The only thing to be aware of is that because the hardware is all metal, it can feel slightly heavier than a standard collar, though on a Weimaraner that's unlikely to be noticeable. Many owners use it as their one collar for everything. I'd say it's a cleaner, more durable solution than rotating between a 'nice' collar and a swim collar — which people often end up doing with biothane when this problem hits.

Glad it makes sense — biothane gets recommended so widely that people assume it handles all water, and it usually does, but peat is genuinely harsh on surface coatings. The Ruffwear Confluence should be a much better match for the Exe. Measure twice before ordering and she should be set for years of river swimming.
