Ex Input:
We have three large dogs - two malamutes and a husky mix. I'd read a few of the reviews on here that said that these treats were only good for large dogs, so I figured they'd be perfect for my three chow hounds. Unfortunately these are much smaller than I thought they were. Two, three bites tops and my dogs would have them down, and they didn't seem to like them as much as they like their regular bones (cheap, regular bones). So, nope, I don't think that these are that great, and apparently neither did my dogs.

Ex Input:
These are the worst gluten free cookies I have ever tasted.  They were hard, dry and tasted like tapioca flour.  Avoid these at all cost.

I used quotes around the word tea because I doubt that the bags contain tea.  I wouldn't be surprised if the bags contained ground up sticks instead of tea.  I would not give this product a single star; it deserves zero stars in my opinion. This tool is not allowing me to continue without giving the product at least one star.
