Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
It sounds like she may have had a seizure. Is she acting normal now? Sometimes after a seizure dogs will have a period of not acting like themselves- some will be withdrawn, some will be more social and clingy, some will be aggressive. If this was her first event, you can continue to monitor her but I recommend keeping a journal and making note of any further issues or episodes. If she has another one, i recommend an appointment with your regular vet as there may be something going on with her causing this. Alternatively, you can make an appointment for an exam and basic screening blood work to rule out metabolic issues that can cause seizures such as low blood sugar, liver disease or renal disease.
There are lots of things that can cause seizures. In older pets it is more likely to be something related to inflammation of the tissues that surround the brain and spinal cord (meningitis) which in dogs is usually immune mediated or inflammatory and rarely contagious, a condition called cryptogenic epilepsy (which is older onset epilepsy for which an underlying cause cannot be identified) or cancer. Your vet can perform a basic work up and refer you to a neurologist if necessary.
