I bought this specific food on the recommendation of the veterinarian (recommendation for the type of food and not for the brand), and I chose this particular brand because it had/has a relatively good price compared to other (more famous in Greece) prescription foods. It has been doing an excellent job so far for my elderly Labrador mix with liver sensitivity. The dog has regained energy, gained back the weight it had lost, and overall is more lively. The dog likes the food and eats it with pleasure, despite the recent change from its previous food. Of course, the dog also takes additional liver vitamins, but it is noticeable that the food - in its part that corresponds to the well-being of this particular dog - does its job, and more! Personally, I recommend it.
