Gabapentin Dosage for a 70 lb Dog

Gabapentin in dogs is typically dosed in the range of 5-30 mg/kg every 8-12 hours depending on the indication. Pain dosing tends to be on the higher end of this range; mild anxiety or pre-vet-visit dosing often starts lower. For a 70 lb (31.8 kg) dog, this gives a range that a licensed vet will narrow down based on the indication, your dog's age, kidney/liver function, and any other medications.

Gabapentin (gabapentin) is widely used in dogs in the 70 lb range, but "safe" depends on the specific dog, not just the weight. Large breeds carry higher rates of orthopedic disease (hip dysplasia, cruciate ligament rupture, arthritis) — making pain management drugs more frequently prescribed. They also have higher rates of cancer, which can affect both drug choice and dosing for many medications. A licensed vet will check your dog's history, current medications, and any underlying conditions before prescribing.

The most common things to watch for are: Sedation, wobbliness, or stumbling in the first few days (often resolves with steady dosing); Pronounced clumsiness or inability to stand — call vet (dose may be too high); GI upset (uncommon but possible). If you see anything concerning, contact a vet. For large dogs specifically: Large breeds carry higher rates of orthopedic disease (hip dysplasia, cruciate ligament rupture, arthritis) — making pain management drugs more frequently prescribed.

Gabapentin is a human-labeled drug, and a controlled substance in Virginia, so a veterinarian needs to examine your pet in person before prescribing it.
