Start With the Right Fit, Not the Cleaning Cloth
Care for a 4.0 mm Fur Saver begins before the first walk. A chain that slides on and off easily but sits too loosely can shift during use, while one that barely clears the head is hard to manage. Herm Sprenger sizes are measured from end of ring to end of ring, and the catalog notes that sizing can vary by about 1/2 inch. Measure your dog's neck, then add approximately 2"–3" so the chain fits over the head and sits properly. The available sizes are 50 cm (approx. 20"), 54 cm (approx. 21/22"), 60 cm (approx. 24"), and 65 cm (approx. 26").

A Simple Cleaning Routine for Stainless Steel Links
The supplied product record does not include a manufacturer cleaning procedure, so the steps below are general stainless steel chain collar maintenance rather than a Herm Sprenger instruction. Use them as a practical starting point and check the chain after each cleaning.
- Rinse after outdoor use: Fresh water removes loose dirt, dust, and everyday outdoor residue from the links before it dries into the joints.
- Wash with mild soap and warm water: Work a small amount of mild soap into the links, then rinse thoroughly. Avoid harsh chemicals that could leave residue on a collar that sits against fur.
- Dry the chain completely: Towel-dry the links and let the chain air-dry fully before storage. Trapped moisture is the most common cause of surface rust on stainless steel.
- Check the joints and ring: After drying, open and close the chain a few times and look for stiffness, grit, or discoloration around the ring and link connections.
Rust Prevention Starts With Storage and Inspection
Stainless steel resists rust, but it is not rust-proof. Store the Fur Saver dry and loosely coiled rather than damp in a training bag. After a wet or muddy walk, rinse and dry the chain before putting it away. If you notice brown spots, clean them early with mild soap and a soft cloth rather than letting them sit. The catalog does not list a specific rust-removal product or schedule, so treat any discoloration as a prompt to inspect the chain more closely.
What to Check Before Every Use
- Ring and link connections: Look for bent links, gaps at the ring, or rough edges that could catch fur. The Fur Saver style is designed for long-haired dogs, so a damaged link is more likely to pull coat.
- Size and fit: Recheck the fit if your dog's coat has thickened or thinned, or if the chain has started slipping over the head too easily.
- Cleanliness of the chain: Grit in the links can make the chain stiff and less comfortable. A quick rinse and dry keeps the movement smooth.

What the Supplied Information Does Not Cover
The product record does not include a manufacturer cleaning schedule, drying time, lubricant recommendation, or rust-removal procedure. It also does not list a warranty or replacement policy. If you need those details, confirm them with the manufacturer or the store before relying on a general routine. The care steps above are based on the supplied sizing and material information and on common stainless steel maintenance practice, not on a Herm Sprenger care sheet.
