Questions & Answers

19 Customer Questions

How do you measure the prong? What part are you lining up against the ruler?
Answer by ChewyDec 11, 2021
The prongs are measured by their gauge (or thickness), not by their length. The 12 inch collar uses links that are 1+1/6 inch long with a thickness of 2.25 millimeters. The 16 inch collar uses links that are 1+7/16 inch long with a thickness of 3.0 millimeters. The 18 inch collar uses links that are 1+1/2 inch long with a thickness of 3.2 millimeters. The 20 inch collar uses links that are 1+3/4 inch long with a thickness of 4.0 millimeters.

where do you measure to get the millimeter size?
Answer by ChewyJun 24, 2018
The millimeter measurements are based on the circumference or thickness of the link.

How many 2.25 mm links would i need to get the 12 inch collar to 18 inches?
Answer by ChewyAug 03, 2019
You would need 4-5 2.25 mm links to reach 18 inches on the 12 inch collar.

Why is it listed as Herm Sprenger but under the description the brand name is Coastal Pet Products?
Answer by ChewyMar 30, 2021
Coastal Pet is a certified distributor of Herm Sprenger and these collars are authentic. You can always verify the authenticity of your Herm Spenger collar, as every Sprenger collar is stamped with a brand name HS-Germany (HS-GERMAN INOX / HS-CUROGAN) on the rings or swivels.

Just what I needed

The collar we ordered was just a little too small and the next biggest size would have been way too big. The customer rep found exactly what we needed. And he helped me out by fining a free shipping coupon.

Extra Links

I bought these thinking I would need them, I didn’t. but even though I didn’t. They were still good quality and definitely something to use if your dog just needs the next size. I got the size 14 prong collar, and actually had to take a link out of the prong collar. But I was still happy with the way these looked and the quality and the size.
