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.

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 minute. It tends to be elevated in heart failure. This information can help guide her veterinarian as well. I hope this information helps!
