My senior dog has CHF and coughs. Will Lasix help her breathe easier?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Pinscher | Female | spayed | 12 lbs

My 12 year old MinPin was diagnosed with CHF. Local vet says there is nothing that can be done. She coughs, sneezes, etc. and I was wondering if Lasix (amount) would alleviate her condition.

Yes Lasix can help dogs with CHF but the dosage can only be determined by the prescribing vet. Legally we cannot prescribe it, and its usage has to be monitored by a vet as it can have some serious side effects like dehydration, weakness, collapse, balance problems, electrolyte imbalance, lack of urine production, and a racing heart beat. There are other medications that can be used to control the symptoms of CHF, they won't cure it, but they will make her more comfortable. I'd talk to Lucy's vet about Lasix and other medication. I hope this helps.

My dog Tibby is 13 yrs old. diagnosed 10 yrs ago with enlarged heart, CHF, and stage 4 heart murmur. She’s on Enalapril, Vetmedin, lasix 20 mg split in half 2x daily. regular Vet is out with covid with staff so can’t take her there. She hacks deep fr
Thank you for submitting your question regarding Tibby. I am sorry to hear that she has been struggling. I, unfortunately, do not recommend changing her lasix dose without having her seen by a veterinarian. If hers is not available, then I would try another hospital near by. The reason is that she needs to have her blood work carefully monitored while taking heart medications. Lasix in particular can cause kidney problems. Also, heart failure dogs can have fluid build up not only in the chest, but in her belly as well. Finally, it is not common, but there could be another reason for her increased cough. For example, she could have acquired a respiratory tract infection. The veterinarian needs to examine her, likely monitor her blood work and then make a dose change (if warranted) based on all of this information together. In the meantime, count how many breathes per minute she take while she is resting or sleeping. In a healthy dog, this number is typically less than 30 breathes per mi

My 15-year old mini dachshund has suffered with a hacking cough/wheezing for over a year. A year ago, her x-ray showed no enlarged heart and we tried Prednisone for a few weeks, but there was no marked improvement. Yesterday, the x-ray shows enlarg
Oh no! This sounds very serious and the Lasix alone probably isn't enough to control her symptoms. If she is this sick you should definitely take Roxy back in to the vet to perhaps up her dose of Lasix (there is often a wide range that you can give pets until symptoms resolve) or give her actual heart medication. If the heart is not addressed directly (with medications), then no matter how much Lasix you give, the lungs will continue to fill with fluid due to the direct relationship that is shared between the heart and lungs. This website link discusses the use of both Lasix and heart medications (Enalapril) together in pets with signs of congestive heart failure, which is likely Roxy's condition. http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=537

The vet said she has fluid in lungs and murmur in heart. He has her on Lasiks. She is also 15 years old. She is very weak and don't eat but a few bites of food a day. How long can she last like that?
It depends. Some dogs with appropriately managed congestive heart failure can live for years. Other dogs may only live days. Lasix is good for removing fluid from the lungs, but it is rarely used alone in treatment of congestive heart failure. Medications like enalapril and Vetmedin are commonly used alongside Lasix. I would recommend discussing these additional medications with your vet. https://www.petcoach.co/dog/condition/congestive-heart-failure/

My dog was diagnosed with CHF. His abdomen is still swollen. Lasix 40mg BID was reduced to 20 BID due to slight increase in labs for kidneys. His coughing is worse with the lowered dose. Should I ask the vet to change meds? He’s also on Pimobendan co
Hi there, you could try increasing it to 30 mg twice a day. In general a standard dose is 2mg/kg twice a day. If frusemide should not work , a new diuretic could be added such as spironolactone. I would recommend to discuss this with your vet. Hope this helps !

Syncope or fainting is common with progressive heart disease and it is possible she may also require additional medications alongside the lasix which are diuretics which reduce fluid build up on the lungs, if fainting is happening. I would recommend an emergency vet visit to assess fluid build up on the lungs and to try stabilise ger condition

Hi there, I have a 10 year old Maltese shitszu he quite a while ago was diagnosed with a heart murmur or failure I think, he is currently on heart medication and frusemide to clear fluid from the lungs. He keeps coughing I have taken him to the vet n
Hello, and thanks for your question. Harry may need an increase in his furosemide dose, or sometimes I will tell owners to give an extra dose occasionally as needed - but it depends on the dog's symptoms, kidney function, and current dose of medication (whether the furosemide can be safely increased from the current dose). Furosemide cannot simply be increased indefinitely, or it can cause kidney problems or overly dehydrate the animal. Harry's normal vet will be the only one able to answer this question, since they know his current dose, weight, and medical history. Hope this helps!

My 14 year old shihzue has congestive heart failure. Tonight she is struggling to breath and making a noise when she breathes. She takes furosemide 10 mg every morning and every night. I gave her extra dose an hour ago hoping it would help her. What
Thanks for using Boop by Petco! This could be serious as she may require not only higher doses of furosemide but also perhaps other medications such as pimobendan or other diuretics. If Minnie is struggling to breathe as it appears, I think it would be best to have her evaluated at as soon as possible as this could represent a medical emergency since she is possibly in heart failure. They would be able to check if she needs to have oxygen therapy and these medications added to her medication protocol. Good luck and have a good night!

I have an 11 yr old diabetic dog. Diabetes is regulated. Just diagnosed with an enlarged heart and liver. Is Lasix a good med to put him on? Any food or vitamin recommendations?
Lasix is a diuretic medication used to decrease fluid in the lung if there is evidence of congestive heart failure. The best way to diagnose heart disease is with an echocardiogram, but since mainly veterinary specialists perform this procedure veterinarians often prescribe Lasix based on heart changes and evidence of pulmonary edema fluid on x-rays. If Fred's diabetes is well regulated it may not be worthwhile to change his food. There are some therapeutic diets that are formulated to have lower sodium and increased amounts of omega 3 fatty acids that may benefit patients with heart disease, but since diet plays an important role in glucose regulation there's a chance Fred's insulin requirements could change with a new diet. Depending on the type of heart disease diagnosed or suspected some veterinarians recommend a taurine supplement or fatty acid supplement. You could ask your veterinarian if either of these would be recommended in Fred's case.

Thanks for using Boop by Petco. I am so sorry to hear about Bizou! Unfortunately, if he is in congestive heart failure, the only treatment is the lasix pill (furosemide). Depending on how severe his condition is, he may not survive without hospitalization with oxygen and injectible lasix. Your vet may have a strong suspicion of this if Bizou has a heart murmur and many crackles in the lungs (we can hear with the stethoscope). However, even that is not enough to definitively diagnose it. I have seen a couple dogs I was sure were in heart failure and when I took the x-rays, it turned out to be pneumonia or cancer. If you can at all afford it, go for the xrays so you at least know what you are dealing with - if it's cancer instead of heart failure, that may change your approach. If it is heart failure, it will give a clue as to how serious. If you can't afford the x-rays, treat for whatever the vet thinks is most likely. If heart failure is it, the most commonly prescribed medicati

Hi there and thank you for using pet coach to address your concern. The lasix that she is on is the medication used to help remove edema as it is what we call a diuretic. It is quite effective at this too. A faster way of getting fluid out of the lungs is giving this medication intravenously. I will typically do this for emergencies that are having difficulties breathing and need immediate treatment. The lasix should begin to work shortly after you have given it. If she is still having symptoms then I would contact your vet on the phone and see if your vet wants to adjust any of the medications she is currently on. I hope this helps! Please let me know if you have any other questions or concerns. I am also available via consultation if needed.
