Senior dog with enlarged heart. Will meds help breathing & eating?

There are many medications which can be used to support a failing heart and should be used alongside diuretics in order to help support the function of the heart, reduce fluid build up in the lungs and abdomen and control blood pressure if required. Unfortunately, no cure is available and medications should be adjusted as Zoe's condition changes; many dogs can live for months-years with a heart condition depending on the severity of other health complications which can also occur as they age. Without a full history of all her complaints and recent tests it is impossible to assess her medium-long term prognosis

Vetmedin does not increase the heart size. Since I don't know how much your dog weighs I cannot comment on the dose. If you would like to post again with her weight then we can maybe help you determine if that is an overdose. You can always talk to your vet about changing the medication - I would not change anything without speaking to them first. Is she taking any other medications for CHF like furosemide or enalapril? If so, the enalapril is most likely causing the increase in heart rate after administration. None of the medications however, will cause the hear to enlarge. The heart is enlarging due to the normal course of the disease. The medications only help to support the heart - they will not stop the progression of the disease. Hope this helps. Best wishes.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. I am sorry that Odie isn't feeling well. The heart on the x-rays is very big, so treatment for the heart disease is a good idea. One of the medications given typically with heart disease is a drug called Furosemide, and this usually makes them drink and pee a lot. Other medications for heart disease including Benazepril (Fortekor) and Pimobendan (Vetmedin). Benazepril can be hard on the kidneys so follow up bloodwork is recommended. If Odie is not improving with the medications he might need higher doses. Also, if he isn't eating and drinking, I would be concerned about another disease process going on, and would recommend bloodwork. You can always try a 24 hour emergency center if you can't get into your local vet for a consult. I hope he feels better soon. I wouldn't change any medications you are giving now without talking to a vet first, and it sounds like Odie needs to be seen soon. Best of luck with Odie.

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.

No, I am afraid, an enlarged heart will not shrink, and there are also no medications that make it shrink again. However, if the heart is causing problems then your veterinarian can prescribe medications to help it with its job, ie increase the effectiveness of the beating of the heart, and thus lengthen her life ensuring a good quality of life.

I'm so sorry Duke is having heart and lung problems! I am very concerned that he has not eaten for several days and has no energy. He may potentially have something else going on besides his previously diagnosed heart and lung issues. I would recommend you take him back in to your vet as soon as possible to be evaluated. Often with heart disease, dogs need a combination of medication, including furosemide and pimobendan (the cardisure), and potentially a blood pressure medication. If he is not eating he may need more aggressive treatment and potentially injectable medication. He also may need another x-ray to see how his lungs look. He may need blood work to make sure his kidneys are okay as well as check his electrolytes. Again, I'm so sorry Duke doesn't feel well. Heart disease can be difficult to manage and is progressive, so over time medications sometimes have to be adjusted and/or dosages changed. I hope he starts feeling better soon. Your vet will help you determine what is the next best step for him! Good luck!

Thank you for submitting your question regarding Adrian. I am sorry to hear about all of her recent troubles. I would give her water through a syringe in small frequent amounts. One of the main medications for heart failure is furosemide (lasix). This is a diuretic to pull fluid off the lungs. This medication is life saving, but can cause dehydration and secondary kidney damage. So it is important for her to stay hydrated. Hopefully her attitude and appetite will pick up once the medications are working. Her breathing rate and effort are big indicators if the heart drugs are working. Her respiratory rate should be less than 30 breaths/min when resting if the fluid has resolved. She should also breathe easily and without obvious effort. The diarrhea can be secondary to the heart disease itself or even the stress of illness. Hopefully it will resolve with the new medication. If she is struggling to breathe, isn't eating or drinking well tomorrow and the diarrhea persists, she will need to see her veterinarian again. It is important to carefully monitor her blood work and blood pressure after starting heart medications. I hope this information helps!
