Puppy improved with Lasix, now sick again. Is it heart related?

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

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.

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.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Heart disease affecting the lungs occurs when the heart is unable to pump the blood forward well, and the pressure back-up in the lungs causes fluid to seep out into the lungs, and the lungs fill up like a sponge filling up with water. The medications for heart disease include a diuretic which will essentially 'ring out' that sponge. It pulls fluid out of the body, and therefore out of the lungs. For this reason Rocky will drink and pee a lot on the medication. The other medications work by making the heart pump better (Pimobendan is the usual drug of choice for this) as well as decreasing the blood pressure so the heart can pump in a forward direction more easily (ACE inhibitor usually). Depending on the level of heart disease your vet will choose 1, or all 3, of these medications. Some dogs respond very well to medications and can live for a while, with changes in the medications every once and a while. Some dogs unfortunately don't respond well to the medication. It all depends on how severe the heart is at this point, as well as how well Rocky will respond to medications. You can get an echo (ultrasound of the heart) to determine exactly how bad the heart is at this point, or just see how he responds to the medications. His best chance is to be diligent about his medications, don't let them run out as he will need to be on them for the rest of his life, and do your follow up appointments as your vet is recommending. Best of luck with Rocky.

Yes, it is quite possible the pneumonia has not resolved. She needs urgent reassessment by a vet and further medication, possibly intravenous fluids and antibiotics in order to stabilise her condition. Such severe pneumonia in a young pup is very concerning and can be fatal due to lung scarring and collapse. It is possible there may be underlying birth defects contributing to the original condition and/or her poor response to treatment

Hi there and thank you for using pet coach to address your concern. If your puppy is not improving after being on medications for a week or is worsening, I would schedule a recheck with your vet. Sometimes switching to a different antibiotic may help. The particular antibiotic that your puppy is on may also cause growth defects, but this is rarely seen. I typically use Clavamox or doxycycline for Respiratory bugs in puppies. Another alternative treatment your vet might consider, is initiating nebulization therapy to help relieve some of the symptoms your puppy is experiencing. I hope this helps and I hope your puppy gets better soon! Please contact me if you have any other questions or concerns. I am also available via consultation if needed. Please remember to write this post as helpful or not. Thank you!

Hi there and thank you for using pet coach to address your concern. I am sorry to hear that Baxter is not doing well. The cause of pulmonary edema which is fluid in the lungs, can be do too many things. I would want to rule out heart disease, pneumonia, other infection, cancer, or systemic disease. If your vet has performed Diagnostics already and has administered treatments but Baxter is still not improving, then I would suggest seeking a secondary opinion from a specialist. Based on the previous Diagnostics that were performed and treatments that were administered, the internal medicine specialist may be able to help more in determining what other possibilities could be causing the fluid accumulation. I hope this helps! I hope Baxter gets better soon. Please let me know if you have any other questions or concerns that you may have. I am also available by phone or text base consultation if needed
