Took Tilly to the vets today. She has been acting a bit strange this last week not eating crying a lot also showing signs of aggression towards 2 dogs that came to close to her treats when out on walks which is not like her. They said she is having a phantom pregnancy and that it can take up to 3 weeks to go. She is booked in to be done beginning of June which we might have to change. Does anyone have any experience of this. She has lost 1 kg in weight.
