Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 10 years and 1 month old | 60 lbs
My dog was diagnosed with congestive heart failure about a little over a month ago - she was prescribed 40mg of furosemide twice a day - just over the weekend she started coughing again, my vet told me today to increase the dose to 50mg twice a day - since I was talking to her I noticed that the phlegm is white and VERY thick as well as she vomited bright yellow (only once). Should I be concerned or wait 24 hours to call and take her back in? She is eating and acting normal otherwise.
