She was fine all today, went with her for her walk, she had her dinner then laid down next to us whilst we ate ours then all of a sudden, woke up, vomited and went into a sort of dozy stupor, really not herself at all. Straight to vet who stayed late to see her, they were still open thank goodness, also he saw her yesterday for something completely unrelated and could immediately see the difference in her. Said she was quite dehydrated and they will do tests tonight and an ultrasound to see what is wrong but possible her gut is twisted or something like that. She is so little, only 5 months old, the house seems so quiet without her and I am just sitting waiting for the vet to ring to tell me if they will need to operate on her. Not really sure why I am posting but feeling a bit shocked and very upset thinking of her staying at the vet feeling so miserable and ill, I can't bear it. :( Also DS 5 now upset as had to take him with me and he heard the word operate and thinks they are going to put her to sleep as we had our cat PTS just before Christmas. I can't believe she is so ill so suddenly. Has anyone had a dog with this condition?
