My dog ate furosemide. Is he okay after taking other prescribed meds?
Thanks for using Petco Pet Education Center, formerly Petcoach! If you meant a 12.5mg tablet of furosemide, he should be ok as long as he does not have underlying kidney disease. He will be more thirsty and will urinate more for the next 24-48 hours. Best of luck!

Can I dissolve my dog's Lasix pill in water for easier dosing?
Hello, The drug insert for Lasix (furosemide) states that it does not dissolve well in water. I worry that if the drug doesn't dissolve completely, she may be receiving improper and irregular doses. Unfortunately, it does not look like a good choice for this medication. I would recommend hiding the Lasix in a little piece of food if possible. There may also be an option for you to get the drug compounded by a special pharmacy into a liquid formulation. These pharmacies can also add meat flavorings, etc to make the medication taste better. Your veterinarian likely already has a relationship with a pharmacy that does this and should be able to help you. I hope this is helpful! Thanks for using Petco Pet Education Center, formerly Petcoach.

Diabetic dog with enlarged heart: Lasix, food, and vitamin advice?
Lasix is a diuretic medication used to decrease fluid in the lung if there is evidence of congestive heart failure. The best way to diagnose heart disease is with an echocardiogram, but since mainly veterinary specialists perform this procedure veterinarians often prescribe Lasix based on heart changes and evidence of pulmonary edema fluid on x-rays. If Fred's diabetes is well regulated it may not be worthwhile to change his food. There are some therapeutic diets that are formulated to have lower sodium and increased amounts of omega 3 fatty acids that may benefit patients with heart disease, but since diet plays an important role in glucose regulation there's a chance Fred's insulin requirements could change with a new diet. Depending on the type of heart disease diagnosed or suspected some veterinarians recommend a taurine supplement or fatty acid supplement. You could ask your veterinarian if either of these would be recommended in Fred's case.

My senior dog has CHF and coughs. Will Lasix help her breathe easier?
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.

My dog is worse after Lasix for heart failure. Is medication to blame?
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
