Hi Bea..Listen love...You've said nothing about what ails Trixie...If she's just 'off her chews', it could be absolutely anything. I assume the emergency vet has said that they will see her? That's the first thing. First, the diagnosis, then the treatment, then the recovery. The worst thing you can do is cry and fret..that will just make her more frightened. You need to be calm for her, darling..Time enough to worry when there's something concrete to worry about. She's a healthy, happy little dog and if she's not well, that's all it is until it's something else. Be patient, positive and stay calm.
Keep us informed, please love..xx
