My senior dog won't eat after Lasix. Is appetite loss normal?

Updated On September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Female | spayed | 6 lbs

Hi...I have a 12 year old yorkie that I had overnight at the Vet and was treated with Lasix for possible CHF...I brought her home yesterday with continued meds and lasix pills but she won’t eat and can’t give meds cuz her mouth is tiny to stuff pills down...does lasix reduce appetite? Also she has vomited 2x... she could possibly have developed pneumonia why also is antibiotics. Thank you for your help.

No, loss of appetite is not a side effect of lasix. I'm not sure what the vet gave Pheobe antibiotics, you need to ask the vet why they were given. If she's not eating in the morning, take her back into the vet.
