Best product on the market. My dogs has been on it for four years following the recommendation from his Vet and the Cardiology Specialist at the Veterinary School in London. The small pellets make it easy for small breed to eat. It looks like there are all the right supplements to support heart function that have been described in the scientific literature, so there is no need to buy other expensive supplements. Will recommend to any pet owner whose dog has been diagnosed with heart disease.
