I was recommended this by my vet for my Maltese as she has a condition that requires it. She seems happy with the biscuits and hopefully they will be helping her heart at the same time.
Customer recommends this product
My little dog has a Grade 4/5 heart murmur so decided to transfer onto this cardiac specific dog biscuit. Anything to help prolong her health. She loves it. Biscuits are a reasonable size and this means she actually crunches them up instead of being lazy and just swallowing them.
Customer recommends this product
Product necessary due to recent heart murmur.
Customer recommends this product
I have been giving this to my dog since she was diagnosed with degenerative cardiomyopathy. She has just had her yearly review and her heart is no worse so this food together with her heart tablets must be doing their job which is great.

Below are some recent questions we've received regarding ROYAL CANIN® Cardiac Adult Dog Food, including answers from our team.
Yvonne
Can I feed my dog Royal canin cardiac kibble with the loaf as she will not eat the kibble on its own?
You can generally mix Royal Canin Cardiac Adult kibble with the loaf version to encourage your dog to eat, especially if she refuses the kibble alone. Mixing the two forms can help improve palatability and make mealtime easier for a picky or unwell dog.
However, here are a few important points:
Portion control: Make sure you’re still feeding the correct total daily amount recommended for your dog’s weight and condition, combining kibble and loaf accordingly.
Diet consistency: Both products are formulated to work together as part of the cardiac diet, so mixing them won’t disrupt the nutritional balance.
Check with your vet: Since this is a prescription diet for a specific heart condition, it’s always best to confirm with your vet that mixing the forms is okay for your dog’s specific situation.
If she still refuses kibble alone, mixing in some loaf or even a bit of warm water to soften the kibble can help.

Can my boy have this kibble along with his meds Vetmedin.
Yes this can be used in a dog who is on Vetmedin. It is usually advised to given Vetemedin on an empty stomach, at least 1 hour before food. I recommend discussing with your vet about how to dose the Vetmedin as it is a prescription only medication.
This food is also a veterinary diet so you should run it's use past your vet just in case.

My vet has prescribed Royal Canine Cardiac dry food for my dog. Coould you please advise me how to feed it. Do I add water to it, or serve it dry - and does it need something else like a slice of Nature Diet. With many thanks.
Ideally you do not give any other food as that will upset the balance of nutrients the diet is trying to achieve. You can give it dry (most people do) or add water, whatever your dog prefers it. You must make sure water is available at all times. This sort of diet is rarely as enjoyable to eat as good quality wet diets, so you might find that your dog eats it without any enjoyment and not in great quantities. This is not a medical concern (in fact lots of dogs need to lose weight and so eating less is a good thing). However it can be difficult for caring owners to accept, regardless of being healthier.
