Cardalis Medium Dog Tablets 5mg/40mg

Cardalis is a brown, oblong shaped tablet and is for the treatment of congestive heart failure in dogs. They are supplied in 2.5mg/20mg, 5mg/40mg and 10mg/80mg tablets and can be sold in either individual tablets or packs of 30. The active ingredients are benazepril hydrochloride and spironolactone.

Cardalis is a prescription item and will be sent once a valid prescription is received. Please follow the instructions given by your vet.

Congestive heart failure is when your dog's heart has trouble pumping blood to the rest of the body. This can be caused by old age, an injury or an infection. In some cases, dog's can be born with this defect.

Early symptoms can be:

. Coughing more than usual

. Tiring easily

. Hard time breathing

. Swollen belly

Why Cardalis? Cardalis is different to other medications as it combines both benazepril and spironolactone, which means only one treatment is required. By giving both these ingredients, owners with dogs suffering with heart failure are 3 times less likely to see any deterioration in health or death due to heart failure than giving just benazepril alone.

If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.

Excellent service and reasonable prices


I have a very elderly cat - 18 - and a year ago she became very thin and couldnt keep anything down. The vet recommended trying Royal Canin Feline Sensitive wet food and it literally saved her life! I immediately started buying it from Pet Drugs online and it brought her back to full health within a month or two and even a year on she's extremely well for 18 and her joints are so much better - she can once again jump up on a chair and tear around like a kitten. To me this proves how much rubbish there is in other cat food products. Pet Drugs online supply high quality foods. I now regularly buy the Royal Canin wet food in packs of 48 from Pet Drugs online who give a fantastic service - speedy delivery and much cheaper than buying from the vet!
