I decided to purchase this product based on a blog by one of the supplement oriented doctors on the internet, hyping erythritol as superior to xylitol, which I use regularly and find the closest to sugar in taste with almost no aftertaste and no side effects to my knowledge.  The problem I find with erythritol is its lack of flavor.  On cereal, I barely notice any real sweetness, even when I put as much as a tablespoon and a half on a normal size bowl.  When I use Ideal, the name of the xylitol brand I use, it has the same sweetness as sugar in the same proportion.  Don't get me wrong, erythritol isn't unpleasant, it just has very little sweetness relative to how much you use.  Not worth the price unless you want just a hint of sweetness compared to what you get with sugar or xylitol.

I cringed a little after reading the ingredient list. Way too much grains and not enough quality protein for our dogs. Notice all of them are at the beginning, which means they make up quite a bit of the diet. Soy protein is included but some dogs don't do well with soy (mine) and meat should be the protein source in dog food, not grains. Not recommended for your furry ones.

Negative
