I have 4 dogs all weighing between 50 and 60 pounds ranging in ages 1 to 13. All 4 of them love this one. I have been trying to find the large roll but can only find the small roll. One had been having loose bowels. This has cleared her up almost immediately. One was getting picky but cleans his bowl. The fur is all bright and shiny. The don’t like the chicken one that smell like bologna tho. This one is their favorite.
