Why are my senior dog's seizures worsening despite medication?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 14 years and 10 months old

My 14 year old dog is constanly having short violent seizures where he is either walking or sitting and suddenly it is like an electric current is running through him. He is on 100x2 daily of pexion. He never loses consciousness and then just keeps on walking. They happen every 20-30 minutes. The vet said he had epilepsy but not the true form. He is still eating and drinking and still likes to play but they are becoming worse and are starting to knock him over and his gait is not quite right.

Thank you for submitting your question regarding your dog. I recommend contacting his veterinarian. He will likely need to start another medication to control his seizures. Phenobarbital, potassium bromide and zonisamide are common choices. However, your veterinarian will know his medical history and which would be the best choice. Being able to have his seizures better controlled will improve his quality of life. I hope this information helps!
