I do not see salt listed in the ingredients. Am I correct in assuming this is appropriate for a salt restricted diet?

There is no salt added to this product. The sodium content of this product is naturally occurring and negligible, below 5 milligrams. It is designed to be heart-friendly.

My senior dog has heart failure and would take these supplements daily for his heart, along with his medication. They were a treat for him that he ate well without issue. I can't seem to get these anymore, and that makes me really sad.

Great Supplement

I had been giving this to my 11 year old corgi for a good amt of time and now it seems to have been discontinued. Such a disappointement.

This little treat is great even for the pickiest of dogs. My little dog is a senior with a heart murmur. He really enjoys them and I'm at ease at how they are good for his heart. They're the only bought treats he gets!

Treat for my dog with heart disease

I give this to my dog with CHF and gifted a pack to her sister with heart murmur. Our vet-cardiologist went through the ingredients and deemed it safe, but cautioned

I give this to my dog with CHF and gifted a pack to her sister with heart murmur. Our vet-cardiologist went through the ingredients and deemed it safe, but cautioned us on making sure we give it 2 hours before or after Vetmedin as hawthorn could interact with the drug. One of the heart-friendly treats I can give my dog.

My 16 year old mini Aussie has advanced CHF, so we have adjusted his diet to prescription food. I thought I would try these for his treats, but he is sometimes reluctant to eat them, whereas most treats he takes enthusiastically every time. For the price it just wasn't worth it.

I bought these treats for my tiny senior dogs (11 years old+ chihuahua mixed breeds) thinking they would be appropriate for their age. Unfortunately they are extremely hard & next to impossible for me to break up into smaller pieces by hand. The treats are very small to begin with but are much too hard for my dogs to enjoy,
