I imagine all of its ingredients, vitamins and supplements are good for dogs. But, as other reviewers point out, these "soft chews" taste awful. My German Shepherd does not like them. Worse, the product instructions suggest starting with three to four tablets initially then work your way down to less. No way will my dog eat so many of these. He simply doesn't like them. I have had to cook the tablets into my dog's wet food, which always includes a sizable amount of meat. Even then, he will barely finish the tablets which by then are saturated with the grease from red meat.
