[EX Q]: 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.
[EX A]: Negative

[EX Q]: I had been buying these treats for my cavachon for the past two years. He loved them. The last batch was of noticeably lower quality...dry and crunchy rather than moist and chewy. I don't know if this is due to the shift in manufacturing from the US to China or coincidental. In any event, I will not be buying these any more and have switched to other treats. Note, Amazon would not let me return this item, and I am within the 30 day purchase period. I'm not pleased.
[EX A]: Negative

[EX Q]: I am not trying to be mean or anything but these cookies very very dry and tasted very unpleasant.
