Optimal Feed
I spent a long time looking for a dog food that not only has good ingredients, but also results in small, firm stools.
I tried foods with good ingredients, but with my two Continental Bulldogs, it led to 10 big piles a day. I also had foods where the stool was way too soft (a huge problem on public streets).
This one smells nicely of fish, has good ingredients, and now I get 2x2 firm piles a day.
