Can a steroid injection and cephalexin cause a dog to have a seizure?

Hi – thanks for your email. According to other information you entered, your dog is a 10-year-old boxer. It would be VERY uncommon for steroids or cephalexin to cause a dog to seizure. I'd worry that it is due to some other problem, especially in a 10-year-old boxer. I have never seen either of those drugs cause seizures in dogs.

There are lots of reasons for dogs to seizures. Seizures are considered a symptom and can be caused by many different diseases. An article that might be helpful to you is Seizures in Dogs.

Best of luck!
