Query: Great for pets that are senior or diagnosed with heart issues

I have confidence in Vetri Science and feel good about supporting our dog's health with proven supplements for his heart. Actually these contain the same vitamins recommended for people, but in pet friendly strength. I give it to my mini poodle surrounded with a bit of something yummy for him to eat as it is large to put down his throat. Then I make sure he has a taste of yummies after to make sure it gets down. I recommended any Vetri Science product (I also give him senior vitamin supplement).
