Q4: What should I do if I miss giving my dog a dose?

Answer: If you realize you’ve missed a dose close to the time it was supposed to be administered, give it as soon as possible.

Consistency is key, so setting reminders or alarms can be beneficial.

Q5: Can gabapentin cause dependency or withdrawal symptoms in dogs?

Keeping a behavior log after starting the medication can help identify and discuss any concerns with your veterinarian.

Always provide a comprehensive health history to your vet before starting any medication.
