My dog got extra gabapentin. Is it an overdose or will it harm him?

Updated On September 23rd, 2025

Pet's info: Dog | Shih Tzu | Male | unneutered | 12 years and 11 months old

Quinton takes 50 mg of gabapentin every 12 hrs but I have to break open the capsules and put the powder in his mouth. This morning I think I missed getting all of the 50 mg in his mouth so I gave him a little more. If I gave him too much is this an overdose. He is hard to give meds and he had a little more left after I was sure I got morein his mouth. Will this harm him.

Gabapentin has a pretty wide dosage range, so even if you double the dose it is unlikely to be toxic. The most common symptom of too high a dose is sedation. If you need to break open the pills, a more effective way of making sure that Quinton gets all of the powder would be to mix it in a very small amount of wet dog food.
