How to identify a dog seizure: duration, responsiveness, and position?

Updated on September 23, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 20 lbs

Last night i thought my dog had a seizure (it was dark, and when i looked it seemed like he was shaking). Thankfully he was just itching his back (like in the pic but lying down). I have some questions abt seizures: how long do they last? This lasted about 5 seconds and he stopped when i called him, that wouldnt happen with a seizure right? What position do dogs fall when having an episode? On their sides right? Feel free to tell me more about seizures if i missed an important question please!

Hello, thank you for your question about Alex.

Seizures can have a variety of presentations but most commonly dogs experience generalized shaking/tremoring and they usually fall onto their sides. They are non-responsive to stimuli (calling their name) during this event. Seizures can last for any period of time generally 30 seconds to a few minutes.

There are other more focused types of seizures where small areas of the dog's face/body will twitch and they may remain conscious during these events, but these are less common then the generalized seizures.

I hope this answers all your questions!
