When I first started to buy VitaGravy, my dogs loved it. After a few weeks, they don't seem to care too much for it anymore. They still get it in their kibble every day, and will eventually eat it when they are hungry, but they don't consider it to be a treat anymore. I still buy it because of its beneficial nutritional value and decent price compared to a pill vitamin supplement. One big negative I have noticed about it is that their face is getting dirty from it. They are white dogs and this product tends to cause increased tear and around-the-mouth stains. I used to buy all different flavors of VitaGravy, buy my groomer told me the chicken flavor is best as the beef and pork based flavors can cause an even worse increase in face staining.
