fit healthy 10 year old - small breed - ate as usual today and went for a walk and a swim (dried off and sat in front of fire). Woke me up at 2.30 asking to go outside for a pee (unusual). Since then has been shivering, teeth chattering, eyes staring, not comfortable in any position. Doesn't want to sit in front of fire. No emergency vet though will take her in at 0830. Any ideas if anyone's awake out there?
