Hi Sarah and Maya, welcome. What was the reason for her amputation?

Yep, sounds like phantom pain , which is not at all uncommon, but can be difficult to treat. At six weeks out it might resolve on it's own with additional Gabapentin (what is the dosage/timing and her weight), but sometimes doesn't work on this.

Unfortunately many vets don't know how to help resolve phantom pain and oftentimes medication alone won't fix the problem. One reason you'll see us recommending rehab therapy a lot around here is because these pros are good at diagnosing pain when general vets are stumped. And that's a big reason why Tripawds Foundation will pay for your first rehab visit too, so please ask for a referral to a therapist for Maya. Or, DM me your location and I'll help you locate one.

Sarah, I would get your vets approval to give her a more consistent dosage throughout the day. Better nerve pain relief is achieved  when medication is given in a consistent stream. When pain spirals it is much much harder to bring under control with one dose.

At 62 pounds we typically see a Gabapentin dosage for nerve pain in the 200-300 mg range 3x daily.

One medication alone might not do the trick but it's a good starting point to deliver more consistency. 

Let us know what your vet says. Also here's a few good articles about pain control:
