Hello, i'm a new owner i got 2 babies 1 weeks ago and they're around 9-10 weeks old . Recently one of them started sneezing and she has one eye closed, i took her to the vet yesterday and they told me she has flu, they gave her 2 injections with powder medicine. Today at morning she barked and kept sneezing so i put her in double pouched, but she didn't get better. Can anyone tell me what to do? Answer me as soon as possible please Thank you.
