I have a 9 week old chihuahua, I have only had her for 3 days but she has not had her jabs as the breeder said she is too small and that I should wait a few weeks. I have another dog he is up to date with his jabs, but she has had really bad diarrhea and has been sick today, I don't know whether its because she keeps trying to eat is food or whether it could be something worse, can anyone give me some advice please x
