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.


2.5-5kg - 1/2 x 2.5mg/20mg tablet

5-10kg - 1 x 2.5mg/20mg

10-20kg - 1 x 5mg/40mg

20-40kg - 1 x 10mg/80mg

40-60kg - 1.5 x 10mg/80mg

60-80kg - 2 x 10mg/80mg

The tablets should be given with food, either mixed in with small amount of food before a meal or with the main meal. 

Do not use in dogs intended or used for breeding.

Do not use during pregnancy and lactation.

This is a prescription item and will be sent once a valid prescription is received.

On 21 Oct 2016 Pet Drugs Online responded:
Dear Pauline. Thank you for your feedback on the Frontline Flea Treatment you purchased. I am sorry to hear that you were unhappy with Frontline on your cat but hope that you were happy with our service. Frontline is one of our most popular products and I've not heard of any issues with it hurting a cat's neck. Very rarely a small amount of hair might fall out at the point it is applied on the neck and this could occur with most spot on treatments. It may be worth trying an alternate product such as Advantage that uses a different active ingredient and also making sure that your cat's household environment is also treated with a flea spray. Please do not hesitate to contact me on if we can be of any help. Jon (E-Commerce Manager) 


Quick, efficient, good value for money and keeping him on a low daily dose seems to have helped my cat who has suffered from stress related cystitis.


many various items, several brands, good quality items, quick delivery, easy to navigate site.


fast and as described


Great customer service and far cheaper than vet's prices. A problem with my order (my mistake) was rectified quickly and efficiently. Just a shame I could only order 120 tablets when my prescription was for 100.
