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 quick hassle-free service.

Great prices, exceptional delivery service. What more could you ask for!


The order was sent with their usual speed and efficiency, I have used them for several years now and they have only made one small error (which was swiftly rectified). I cannot find fault as far as my orders are concerned and I will continue to deal with them for all my pets requirements.

Quality product at a great price - just wish a larger size was available. Promt delivery, great service. Thank you.


And always a lot cheaper than the vet


excellent service with prompt delivery at a great price.


I would give you 5 stars but for one reason. The order was incomplete but there was no note to say that it was one of two packages. I therefore had to call you to find out that your warehouse was out of the one type of tinned dog food when the order was placed so it was going to be delivered the following Monday. I had to arrange a different delivery address as I was not going to be in and I did not receive a delivery slot text on the Monday. So a) there should have been a note in the first delivery to say more to follow and b) I should have had a delivery text for the second delivery.


Very easy to use and a quick delivery.
