Seizures in older canines are common and likely related to a brain tumor, kidney disease, diabetes or Cushing's disease, according to the experts at Pedigree.com. While often linked to epilepsy, seizures in older dogs are not likely rooted to the condition unless it was present when the animal was younger.
Immediate veterinary attention is required for any dog that experiences a seizure. When this occurs, owners are encouraged to gently restrain the animal by placing a towel over it to reduce the risk of injury. To avoid being bitten, it is important that owners do not place their hands near the pet's mouth, states Pedigree.com.
