My 45 days old pug puppy is passing yellow water with mucous and sometimes drops of blood.. she was diagnosed with parvo 4 days back and treatment for the same is being given to her ever since. Yesterday her stools had started to become hard.. and all this while there was no sign of blood but today stools are loose and drops of blood also present. Doctor says she will make it as her treatment began as soon as the virus was caught and that such symptoms means she is improving. Please guide!

I know you are worried. You have no option except to listen to your vet, although you could get a second opinion.

Is there some reason you do not trust this vet's advice.
