Dog coughing again on enalapril. Should I give more furosemide?

Updated On September 23rd, 2025

Pet's info: Dog | Maltese | Male | neutered | 10 years and 7 months old | 12 lbs

Hi! Two weeks ago I took my maltese male dog to his vet cause he had this weird cough, turns out his heart expanded cause his arteries are working harder to pump the blood in/out. He was given enalapril 2.5, furosemide 20, cipro 250 and prednisone 5mg for ten days. He got better,but then when I got his first refill for enalapril (cause is for life), I noticed hes back to coughing. Can I give him an extra dose? Should I get a refill for furosemide and give those two combined?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Troy. Poor boy! Do not give him extra enalapril. It sounds like he may need more furosemide. Dogs with heart disease have fluid build up in their lungs because the heart doesn't pump correctly causing the coughing. Furosemide is a diuretic, which means it gets rid of excess fluid helping stop the cough. Take him back into the vet to get more furosemide. I hope this helps!

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!

Dog (female) is approx. 15 yrs old diagnosed with leaky heart valve. She has been taking Enalapril 1 tablet 5 Mg twice a day and most days Furosemide 20 Mg once per day for over one year . Two weeks ago developed heavy cough my vet prescribed Temaril
It sounds as though Dixie is going through a lot at the moment! Yes, Dixie should absolutely continue taking the enalapril and furosemide, unless otherwise directed by the prescribing vet. The hydrocodone/homatropine medication is a cough suppressant, but may make her a bit groggy. The heart valvular insufficiency can progress to congestive heart failure, which can cause a cough to develop as a result of the fluid accumulation in and around the lungs. If her cough continues or worsens, Dixie may need to go back to her vet for another exam and chest x-rays, and may need additional medications to manage her heart disease. I hope that all goes well for her!

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 !

My dog's heart has enlarged and growing into her trachea. Vet has her on vetmedin and enalapril. She is now coughing continuously Is there anything I can give her for the cOugh
Unfortunately, there are no OTC medications you can give your dog for her cough. The cough will be related to her heart disease, and is likely caused by a build up of fluid in her lungs. There are medications you can get from your vet that can help with that help with called diuretics. An example of a diuretic would be furosimide. I would speak to your vet today about possibly putting her on a diuretic to help with her cough.

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

11 y/o shihtzu 14 lbs taken to vet for chronic skin fungus, no other medical hx, I mentioned occasional cough, after listening to lungs, vet stated fluid on her lungs. He gave lasix 12.5mg bid x 1 week & upon return to vet fluid still present, now v
I am sorry to hear about Abbey's problems! Enalapril is used for heart disease as well as other problems such as kidney protein-loss and high blood pressure. We do, however, like to monitor kidney values via bloodwork when giving enalapril along with lasix. Side effects of enalapril can include nausea, diarrhea, or inappetance. In some dogs we can see listlessness or lethargy as a result of drop in blood pressure. Some dogs can also get elevations in potassium levels. It would be best to have a more thorough workup if your vet suspects fluid in the lungs. A cough can be the result of numerous causes in older dogs and the only way to truly tell if there is fluid buildup in the lungs would be an x-ray. The x-ray would also let us evaluate heart size and check for other causes of coughing (infection, tracheal disorders, chronic bronchitis, masses). Depending on what is seen on the x-ray, an ultrasound of the heart may also be recommended (if we do see enlargement of the heart an

My dog has heart failure, currently on pimobendan, frusemide and spironolactone. Recently she had cough and then sudden weakness with high shriek thrice already and I'm thinking of bringing her to vet soon. Most likely she will be started on enalap
I'm sorry to hear that Eight is having this issue. You are correct, her medications will either need to be adjusted or a new one started. She should see the vet as soon as possible. Sounds like she had a fainting type/dizziness episode that is likely related to unregulated heart condition. No, enalapril to the best of my knowledge does not cause a dry cough in dogs but it can have effects on the kidneys. That being said, a high BUN doesn't indicate kidney disease. Elevations of the BUN and CREA together would indicate kidney disease. BUN is not a specific marker for the kidneys, CREA is.

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 Japanese Chin 9 years has been diagnosed with a heart murmur stage 3 .Hes on Vetmedin ,Libeo, and recently Cardalis to reduce the persistant coughing.Unfortunately the Cardalis does not seem to be working .Is there an alternative more effective me
Poor guy. The coughing is mainly due to fluid bulid up in the lungs. If the coughing has not improved then ask you vet if adjustments can be made to his current medications, in particulra the Libeo (Furosemide), which is designed to pull fluid off the lungs, reducing the cough. He is on all the medications currently recommended for heart failure dogs, so the best thing to do is increase his medications and perhaps get him on a cardiac prescription diet (i.e. Hill's Science Diet H/D). Also understand that heart medication is not curing the disease, it is merely managing it to buy your pet more time. Unfortuantely the medication may reach a point where it is no longer effective when the disease has progressed too far. I do hope that we have not reached that point yet, and perhaps can still make adjustments in Kenzo's medications to help manage his heart disease for a while longer.

My min pin has an enlarged heart and is wheezing and coughing.Can i give it some kind of medication to ease it? She was put on enalapril 5 mg cut in half and furosemide 20 mg cut in half but she still wheezes when she gets excited.Is there something
Poor Tata. The furosemide medication that she is on right now is supposed to help clear fluid out of her lungs. If she is still having issues breathing then I would ask your vet if she can safely up her dosage. There is a wide safety range for this medication so chances are she can up. Just remember that heart failure symptoms will never completely resolve with medication. Your goal is to make Tata as comfortable as possible. Best of luck with your pet.
