Sorry to hear little Rosie isn't feeling well! Can I get a little more information?
Does Rosie sound congested, like she has a cold? Any discharge coming from her nose or eyes? Was she running a fever when you took her to the vet on Wed? Is she eating anything at all?
Sorry but I have an appointment that I have to go to now so please cancel this as it is more than 10 minutes past for the reply.
