She actually eats it!

I struggle trying to find supplements for my CHF chihuahua. She hates taking pills and will sniff out anything that doesnt belong in her meals. She hasn't turned

I struggle trying to find supplements for my CHF chihuahua. She hates taking pills and will sniff out anything that doesnt belong in her meals. She hasn't turned down a meal with this stuff in it! I think the bone broth really helps make it paleatable

THAT IT WAS FLAVORLESS

I bought this for my older cat who has been diagnosed with two heart murmurs and heart disease. There aren’t much prescription meds for cats with heart problems

I bought this for my older cat who has been diagnosed with two heart murmurs and heart disease. There aren’t much prescription meds for cats with heart problems and those available are very bitter. This is easy to give in wet food and so far after being on it for about a month I believe it is helping my cat. From watching him when sleeping I am not seeing his heart beating as hard as it was and it seems to be more normal beating. Hopefully with his next vet appointment the murmurs will have closed up some. I also give him omega oil treats that are from another reputable brand that makes crunchy tasty treats cats love.

Not sure...........

Never got a chance to see whether or not this product did any good for my dachshund......I used about 1/3 of it and the rest turned to "stone" - got hard as a rock

ALMOST ..till read LAST INGREDIENT

I was on board and even excited as I thought I had found safe fairly less expensive than other brands cardio supplement for my dog… until that very last listed ingredient

I was on board and even excited as I thought I had found safe fairly less expensive than other brands cardio supplement for my dog… until that very last listed ingredient. Silica…some say non-toxic while others say prevent your pets from this ingredient…I’m like any ingredient that has controversial research is out. Back to Zesty Pets Cardio- more expensive but all the ingredients are completely safe and those few extra dollars are worth my peace of mind…

No issues with flavor.

My cat has no problems with it being added to her food. I’ve tried a couple of supplements before that she would NOT eat at all, even if it was mixed in with wet

Now Cardiovascular Support

I am not sure if this really has helped my cat but I wanted to safeguard her heart due to the beginning signs of cardiomyopathy. The one thing about the product

I am not sure if this really has helped my cat but I wanted to safeguard her heart due to the beginning signs of cardiomyopathy. The one thing about the product was it had to be ground into more of a fine powder to mix better in her wet food. Other than that, she didn't seem to mind taking it.
