The 'triple therapy' - the standard of care for dogs in congestive heart failure. Most cardiac dogs in Stage C will be on all three of these medications.
Why are these prescribed together?
This combination addresses heart failure comprehensively: pimobendan strengthens heart contractions and reduces workload, furosemide removes excess fluid, and benazepril blocks the hormonal cascade that causes fluid retention and harmful cardiac remodeling. Evidence supports this triple combination as the gold standard for CHF management.
How they interact
All three work through different mechanisms and complement each other. Pimobendan + furosemide was shown superior to ACE inhibitor + furosemide in the QUEST study. Adding benazepril to pimobendan + furosemide provides additional RAAS blockade. No adverse interactions between the three.
Dosing and timing tips
Pimobendan: every 12 hours, empty stomach. Furosemide: 1-3 times daily, with or without food. Benazepril: once or twice daily, with or without food. A common schedule: pimobendan 7am and 7pm (empty stomach), furosemide 8am and 8pm (with meals), benazepril with the morning meal.
Monitoring needed
Resting respiratory rate daily. Kidney values and electrolytes every 1-3 months initially, then every 3-6 months when stable. Body weight weekly. Echocardiogram every 3-6 months.
Important warnings
This is a lifelong medication regimen - never stop any of these without vet guidance
If your dog's breathing worsens despite all three medications, contact your vet immediately - dose adjustments or additional medications may be needed
Keep a written medication schedule posted where you feed your dog

Other drug interactions
Pimobendan (Vetmedin) & Furosemide (Lasix)
The most common combination for dogs in congestive heart failure. Pimobendan strengthens the heart while furosemide removes excess fluid from the lungs.
Pimobendan (Vetmedin) & Benazepril
A standard combination for managing heart failure. Pimobendan strengthens the heart while benazepril (an ACE inhibitor) reduces cardiac workload by relaxing blood vessels.
Pimobendan (Vetmedin) & Sotalol
Used together when a dog has both weakened heart muscle and dangerous arrhythmias. Common in Dobermans with DCM. Sotalol controls heart rhythm while pimobendan supports heart function.
Pimobendan (Vetmedin) & Spironolactone
Spironolactone is often added to the treatment regimen for MMVD dogs in heart failure. It provides mild diuretic effects while protecting against harmful cardiac remodeling.
Important:Never start, stop, or adjust your dog's medication without consulting your veterinarian. The dosages and protocols described here are general references - your vet will determine the right approach for your dog based on their individual condition, weight, and overall health.
