My GermanSheppard has no issues throughout the day. She plays and runsaround with our other dog. She eats bot meals breakfast and dinner. She naps and walks. However almost everynight for the past week she wakes up between 2am and 3am and shakes her head repeatedly and tries to scratch something out of her left ear. She asks to go outside but never uses the restroom. She drinks a ton of water then wants back inside. This goes on for 20min to 3hrs. She is just over a year old we got her from a private breeder and she is not fixed and still has yet to have a dog perod and/or gone into heat, as far as we can tell. Also this has happened several time since we got her in August just not over long periods of time until recently. please help with any info you can give. Thank you for your time.
