Gabapentin, a medication primarily used to manage pain and seizures in dogs, can have several potential side effects. While it's generally considered safe when administered correctly, some dogs may experience adverse reactions. side effects of gabapentin in dogs include sedation, dizziness, and ataxia (loss of coordination). These effects can manifest as lethargy, clumsiness, or difficulty walking. Additionally, some dogs may exhibit gastrointestinal disturbances such as vomiting, diarrhoea, or appetite loss.

In rare cases, gabapentin may cause more serious adverse reactions. These can include allergic reactions characterised by swelling of the face, lips, or tongue, difficulty breathing, or hives. Liver toxicity is another uncommon but serious concern, which may present as jaundice (yellowing of the skin and eyes), lethargy, or abnormal behaviour. Some dogs may also experience behavioural changes, such as increased aggression or agitation.

It's crucial to monitor your dog closely when starting gabapentin therapy and to report any unusual symptoms to your veterinarian promptly. Dosage adjustments or discontinuation of the medication may be necessary if severe side effects occur. Always consult with a veterinarian before administering any medication to your dog, and follow their instructions carefully to minimise the risk of adverse reactions.
