Dog with heart disease breathing heavily. Can I give more Furosemide?

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. I'm sorry to hear that Gelly is breathing heavier today - it is possible she is currently in congestive heart failure, meaning she has fluid building up in her lungs. If she is currently receiving Lasix (Furosemide), you can probably give her another dose of that and see if this helps. If she is still breathing rapidly and with abdominal effort, I recommend having her evaluated by a veterinarian right away. If she is unable to get the fluid off of her lungs, she will be unable to oxygenate her blood and can go into respiratory arrest and die. I hope this is helpful!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Roxy! If Roxy is having trouble breathing she needs to see a veterinarian right away. We have to assume she is in congestive heart failure. Just increasing the medication likely will not be enough. You can give her another 1/2 of furosemide while you find an open emergency room. Oral medications are not quick enough in situations like this. She likely needs oxygen and injectable medications. I wish Roxy the best!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Frank! If Frank is having trouble breathing it is best to have him seen sooner than later. It is fine to give an extra dose of furosemide but he may need oxygen and an IV dose of furosemide. It is best for Frank to be seen as soon as possible. I hope this helps and I wish Frank the best!

Thanks for using Petco Pet Education Center, formerly Petcoach. 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 medications are furosemide, enalapril, and pimobendan (though there are others). Finally, if he is still struggling for air, his tongue/gums are any color other than bright pink, or the vet thinks it is serious enough to require oxygen, and you cannot pay for treatment, I would strongly consider euthanasia. Dying by gasping and struggling for air while drowning in your own fluids is a horrible way to go - I've seen it several times. Please feel free to reach out to me via consultation if you'd like to to have a more detailed conversation with you. Best wishes to you and Bizou.

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!

These are all great questions. I’m sorry you are having to navigate through this with Memi but he is lucky to have an owner as dedicated as you are! An increased respiratory rate and/or effort can be indicative of fluid build up in the lungs from heart failure. Sometimes this fluid can be heard on exam with a stethoscope and sometimes it can only be seen on X-rays. In my experience, the severity of the fluid build up correlates with the physical exam findings. Occasionally I may see fluid in an X-ray that I cannot hear on exam so I always recommend doing X-rays if I am suspicious of heart failure. The rate at which fluid builds up in th lungs can vary from dog to dog and case to case. There is no way to anticipate how quickly fluid will accumulate in Memi until it begins to happen. A diuretic like lasix can very effectively remove this fluid but, like with all drugs, has to be used with caution and the patient has to be monitored closely while on it. If Memi is still having difficulty breathing I would recommend requesting a recheck appointment with either your regular veterinarian or your cardiologist. I hope this helps! Please let us know if you have any other questions.

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
