Highlighted Reviews

— Susann

"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."

"I could tell they weren't suitable for a senior toy dog without teeth."

Bottom Line

If you have a senior dog with heart issues, these treats are a great addition to their diet and medication. Be aware of the hardness for dogs with teeth problems.
