My dog with lung cancer is struggling to breathe. ER or wait?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Female | spayed | 14 years old | 39.6 lbs

Angel has lung CA, X-ray 1 week ago showed primary mass increasing in size, lots of new smaller masses, RR currently 46 (vet said 30-40 fine), nasal flaring, use of accessory muscles, and new fine crackles to RLL. She looks comfortable, resting, eyes closed, should we bring her to ER or wait til morning? It’s 2230 right now, could try to get her into regular vet in morning. What could be done to make her comfortable? 1xdose furosemide? Currently on prednisone, gabapentin, CBD. Thanks!!

It's definitely not a good sign and her condition is probably worsening, i would recommend monitoring her very closely if you decide to wait for the morning to take her to your vet as this has the potential to go downhill very fast. regarding Frusamide i would not recommend giving it without making sure she has fluid in her lungs (fine crackles could be a sign of fluids in the lungs but it could be other things as well).
