How to Choose the Right Size Jerk-Ease for My Dog

Updated

Choose by your dog's weight first: Small for dogs up to 20 lbs, Medium for 21–60 lbs, and Large for 61–110 lbs. If your dog sits right at a boundary or pulls hard, sizing up is the safer call — the larger extension gives more stretch and cushioning. If the fit still feels wrong after it arrives, the company says you can reach out to exchange it for a better size.

Size chart

Size Recommended dog weight Product length
Small Up to 20 lbs 8.5 in
Medium 21–60 lbs 9 in
Large 61–110 lbs 9.5 in

Weight is the primary factor because it determines how much the bungee stretches under load. A dog that's too heavy for a size will bottom out the stretch, so the shock absorption you bought it for largely disappears. A dog that's too light won't extend it enough to matter.

When to size up

Two situations justify going one size larger than the chart suggests:

  • Your dog is between sizes. A 20–21 lb dog, for example, sits on the Small/Medium line. Sizing up gives more cushioning.
  • Your dog is a strong puller. The extra stretch in the larger size absorbs more of the sudden jolt.

The trade-off is small: the length difference across sizes is only about an inch (8.5 in to 9.5 in), so sizing up won't noticeably change how the leash handles.

What size does not do

Jerk-Ease reduces shock and strain on your joints and your dog's neck — it does not stop your dog from pulling. If pulling itself is the problem, this is a supplement to training, not a replacement for it.

If your dog is over 110 lbs

The published chart stops at 110 lbs for Large. The site notes that many owners of larger dogs still use it, so if your dog exceeds that range, contact the company directly rather than guessing between sizes.

If you get the wrong size

The company states that if the size doesn't feel right, you can reach out and they'll help you exchange it for a better fit. Check the current exchange terms on the site before ordering, since the page doesn't spell out time limits or shipping details.

Quick decision path

  1. Weigh your dog.
  2. Match the weight to the chart.
  3. If the weight lands on a boundary, or your dog pulls hard, go one size up.
  4. If your dog is over 110 lbs, ask the company before ordering.
  5. If it arrives and feels wrong, request an exchange.
