Epilepsy is a common problem in dogs, and management of this chronic disorder requires a substantial commitment on the part of the pet owner. The aim of this study was to evaluate the impact of epilepsy in dogs on their owners, utilizing an online survey tool. A questionnaire was developed to explore a variety of factors, including seizure history, treatment, outcome, quality of life, costs associated with therapy, and sources of support. A total of 225 responses were obtained. The majority of respondents reported positive scores for overall quality of life, although scores were significantly lower for dogs with poorly controlled epilepsy and medication-related adverse effects. The median monthly expenditure for antiepileptic medication was $51-75. Despite the considerable financial burden placed on the dog owner, monthly medication cost was not associated with quality of life score. Few published reports follow dogs with epilepsy after diagnosis, and there is a growing need to understand the issues associated with long-term management of this population. The results of this study provide useful information that can help veterinary professionals educate owners and set expectations regarding treatment of seizures and quality of life for dogs with epilepsy.
