Can I Give My Dog Gabapentin?

Ask your vet first
Gabapentin is used in dogs, but dosing decisions belong to your veterinarian. Prescription anxiolytic and pain adjunct. Dosing varies widely by purpose (pain, anxiety, seizures), so the amount must come from your vet. Watch for sedation and wobbliness. Some liquid formulations contain xylitol, which is toxic to dogs.

The safe habit

Confirm any medication decision with your veterinarian, who knows your dog's health history and other medications. VetDose shows published reference data, not prescriptions.
