PEMF therapy via devices like the Assisi Loop is one of the more intriguing adjunct options for IVDD dogs — low-risk, easy to use at home, and increasingly recommended by rehab vets, even though the research in dogs is still catching up to the clinical enthusiasm.

Quick answer: The Assisi Loop is a pulsed electromagnetic field (PEMF) therapy device that many canine rehabilitation specialists use alongside conventional IVDD treatment. It works by delivering low-level electromagnetic pulses to tissue, which is thought to support cellular repair, reduce inflammation, and ease pain. Human and animal research on PEMF is promising but not definitive for IVDD specifically. The Assisi Loop costs roughly $250–$300 and delivers around 150 treatment sessions before needing replacement. Most owners use it during crate rest and the early rehab phase as a complement to — never a substitute for — their vet's treatment plan.

What Is PEMF Therapy and How Does It Work?

PEMF stands for pulsed electromagnetic field therapy. It delivers brief, low-intensity electromagnetic pulses through tissue — penetrating skin and muscle to reach the structures underneath, including intervertebral discs and the spinal cord.

The proposed mechanism: those electromagnetic pulses mimic the body’s own bioelectric signals, prompting cells to behave the way they would during normal repair. Specifically, PEMF is thought to increase nitric oxide production at the cellular level, which may reduce local inflammation, improve circulation to injured tissue, and create an environment more conducive to healing.

It sounds a bit sci-fi, I know. But the underlying cellular biology has enough research behind it that major veterinary rehabilitation programs have incorporated PEMF into their protocols. The Merck Veterinary Manual includes electromagnetic therapy among recognized physical rehabilitation modalities for small animals.

The Assisi Loop is simply the most well-known consumer-facing PEMF device marketed specifically for pets. It’s a loop-shaped coil you place around or near the affected area, and it runs a timed treatment cycle automatically.

What PEMF Is (and Isn't)
  • PEMF delivers low-level electromagnetic pulses — it does not use heat, electrical current through the skin, or magnets in the traditional sense
  • It is not the same as magnetic therapy wraps or static magnet products
  • The Assisi Loop is FDA-cleared for use in companion animals
  • It works as an adjunct — meaning alongside other treatment, not instead of it

Does PEMF Actually Help IVDD Dogs?

The honest answer is: probably helpful for comfort and tissue support, but the evidence base specific to IVDD in dogs is still limited.

Here’s what we do know. PEMF therapy has reasonable research support in human medicine for bone healing, wound repair, and pain reduction following orthopedic injuries and surgery. Several veterinary studies have looked at PEMF for post-surgical healing and osteoarthritis pain in dogs, with generally positive findings. Whether those benefits translate specifically to intervertebral disc disease — a different type of injury involving spinal cord compression — is less clearly established.

What rehab vets tend to say (and I’ve heard this consistently from the canine rehabilitation community) is that PEMF is low enough risk that the risk-benefit calculation almost always favors trying it. If it helps, great. If it doesn’t produce a measurable improvement, nothing has been lost.

The areas where PEMF may help an IVDD dog most:

  • Pain modulation: PEMF is widely believed to reduce the perception of pain, which matters enormously during crate rest when your dog is uncomfortable and restless
  • Inflammation reduction: Post-disc-herniation inflammation is part of what causes ongoing nerve damage, and anything that may help calm that process is worth considering
  • Tissue healing: For dogs recovering from IVDD surgery, PEMF may support healing at the surgical site and surrounding musculature
  • Muscle relaxation: Dogs with IVDD often develop secondary muscle spasm, and PEMF may help ease that tension

For context, many IVDD dogs benefit from multiple adjunct therapies working together. I’ve written about both cold laser therapy for IVDD and acupuncture for IVDD elsewhere on this site — PEMF sits in the same category of “evidence is promising, risk is low, and many rehab specialists include it routinely.”

How Do Owners Actually Use the Assisi Loop at Home?

Setting Up a Session

The Assisi Loop is designed to be straightforward. You place the loop around or over the affected spinal region, press the button, and it runs a 15-minute cycle automatically. Most owners do two sessions per day, though protocols can vary based on your vet’s or rehab therapist’s guidance.

For IVDD dogs, the loop is typically positioned over the thoracolumbar (mid-to-lower back) or cervical (neck) spine depending on where the disc herniation occurred. Your dog doesn’t need to be still — many dogs sleep right through it, which is honestly the best-case scenario during crate rest.

A few practical notes from caregivers who’ve used it:

  • Placement matters: Center the loop over the affected disc area as closely as you can based on where your vet has told you the injury is
  • Consistency is key: Two sessions per day, every day, is generally more useful than sporadic sessions
  • It doesn’t get warm: Unlike heating pads, PEMF produces no heat, so there’s no burn risk and no need to monitor closely during sessions
  • Dogs tolerate it well: Most dogs show no reaction at all, which can feel anticlimactic — but that’s normal

When to Start During Recovery

Most rehab specialists suggest introducing PEMF in the subacute phase — typically after the first several days of strict rest, once the most acute inflammation has begun to settle. Starting on day one of a major flare is generally not recommended without veterinary guidance, because the acute inflammatory period involves complex tissue processes that you don’t want to inadvertently disrupt.

If your dog is still in the early days of an episode, focus on the core treatment plan first. The critical first week of IVDD recovery is primarily about strict crate rest and medication compliance — PEMF is a complement to that, not a replacement.

Check With Your Vet Before Starting
  • Do not use PEMF over areas of known or suspected infection or tumor
  • Avoid use in pregnant dogs
  • Check with your vet before using over or near metallic implants (surgical hardware)
  • During the acute inflammatory phase of IVDD, timing matters — get guidance before starting

What Does the Assisi Loop Cost?

The Assisi Loop 2.0 retails for roughly $250–$300. Each unit comes pre-loaded with approximately 150 treatment cycles. Once those cycles are used, the unit either needs to be replaced or returned to the manufacturer for a battery refill service — the latter is typically cheaper than buying a new unit.

At two sessions per day, 150 cycles lasts about 75 days — just over ten weeks. That timeline lines up reasonably well with the active recovery phase for many IVDD cases.

Some veterinary rehabilitation clinics offer PEMF as an in-clinic service, and a handful offer device rental. If you’re unsure whether your dog will respond to PEMF, asking your rehab vet about a rental period before committing to purchase is a smart move.

Getting the Most From Your Assisi Loop
  • Pair sessions with your dog’s natural rest periods — right after a bathroom break is ideal
  • Keep a simple log: note the date, session number, and any behavioral observations
  • Ask your rehab vet to confirm placement position for your dog’s specific disc level
  • Use it consistently rather than sporadically — regularity matters more than perfect timing

Is It Worth It for an IVDD Dog?

That depends on what you’re expecting. If you’re hoping for a dramatic turnaround, PEMF probably isn’t your silver bullet. IVDD recovery is driven primarily by whether the spinal cord is intact, whether surgery was performed when needed, and how well strict rest and rehabilitation are executed. Understanding the five IVDD grades helps put adjunct therapies like PEMF in perspective — a Grade 4 or 5 dog needs a neurologist and a clear treatment decision first, not a loop device.

That said, for dogs in the Grade 1–3 range who are going through conservative management or post-surgical recovery, PEMF is a genuinely reasonable addition to the protocol. The risk is low, the device is easy to use, and many caregivers report that their dogs seem more comfortable during and after sessions.

The broader principle: PEMF won’t rescue an under-treated IVDD dog, but for a well-managed dog on the right treatment path, it may support the healing process in ways that are hard to measure but meaningful.

The most important thing I can tell you about adjunct therapies like the Assisi Loop is this: they work best when everything else is already in place. The crate rest, the medications, the vet check-ins, the rehab exercises — those are the foundation. PEMF is a tool that may help your dog feel better and heal more comfortably along the way. If it gives your dog one easier night during crate rest, that feels worth something to me.

Frequently Asked Questions

Can the Assisi Loop help an IVDD dog recover faster?

There’s no published proof that PEMF therapy shortens IVDD recovery time specifically. Many rehab vets include it as an adjunct because it’s low-risk and may support tissue healing and comfort, but it shouldn’t replace crate rest, medication, or prescribed rehab exercises.

Is the Assisi Loop safe to use at home without a vet?

The Assisi Loop is designed for home use and is generally considered safe, but you should always loop in your vet before starting it during the acute phase of an IVDD episode. There are a small number of contraindications — including pregnancy and use over active infection sites — that your vet should rule out first.

How much does the Assisi Loop cost?

The Assisi Loop 2.0 typically retails between $250 and $300. Each unit has a fixed number of treatment cycles (around 150), after which it needs to be replaced or refilled. Some veterinary clinics offer rental programs, which can be a more affordable way to trial the therapy.

When in IVDD recovery should I start PEMF therapy?

Many rehab specialists introduce PEMF therapy in the subacute phase — roughly after the first few days of strict rest, once the acute inflammation has begun to settle. Starting timing should always be coordinated with your vet or a certified canine rehabilitation therapist.
