Is Gabapentin (Neurontin) Safe for Dogs?
Why it’s conditional
Veterinarians prescribe gabapentin often for dogs with pain, seizures, or anxiety, so the medication itself is well established in pets. The risks come from dose and combinations: human capsules are much larger than small-dog doses, swallowing a bottleful can cause severe sedation, and effects multiply when combined with opioids or other sedatives.
How to keep your pet safe
Ask your vet for a dog-specific prescription and follow it exactly. Keep both your pet’s supply and your own in closed storage, and never double up after a missed dose without veterinary advice.
Warning signs to watch for
Drowsiness, wobbliness, stumbling, lethargy, sometimes vomiting or diarrhea; large ingestions: profound sedation, weakness, collapse.
When to call the vet
If your dog eats an unknown number of capsules, call your veterinarian or a pet poison hotline with the capsule strength. Sedated dogs may need observation until the drug wears off.
Common questions
My dog ate my gabapentin — is it deadly?
Usually not, but a large number of capsules can cause dangerous sedation, and risk is higher in small dogs. Call your vet or a poison hotline with the strength and your dog’s weight.
Can I give my dog my leftover gabapentin for pain?
No. Only give gabapentin that your veterinarian has prescribed for your dog, at the prescribed dose — self-dosing risks under- or overdose.
