Its my understanding (based on discussions with material scientists!) that nylon releases toxins when put into hot water..so..whats the deal with the nylon tea bags?  This wasn't stated anywhere or I wouldn't have bought them.  The company told me they wee FDA approved, but the FDA is only worried about things that will kill you in the short run, or that have very high levels of dangerous chemicals.  Trace amounts are permitted.  Considering how much tea I drink, I'd rather not add toxins to my body every single time.  In contrast Might Leaf, while they have similar looking tea bags, theirs are not nylon and are biodegradable in addition to not being dangerous.  Very disappointed in this product.  They should at least have been upfront about the nylon bags so concerned people can avoid buying them.

Ex Output:
Negative

I have dogs who are 85 pounds. They chewed the bottle toy in less than 10 minutes; trashed it. I have not tried this with a little dog.

My 10 month old Lab needed some brain toys, and this seemed like an ideal option. There is a problem to solve, and the reward is food - what could be better for a Lab? The problem is that she is a chewer, and though she did figure out pretty readily how to get the food out, she was way more interested in chewing on the rope. When I removed the rope - which also made it way easier to get the food out - she then thought it would be more gratifying to chew her way to the food, rather than rise to the intellectual challenge of tipping the bottle and dispensing a treat.  And oh yes, this thing is loud when it hits the floor or cabinets in the kitchen, etc. Pretty durable, considering all she wants to do is chew it and it's not intended as a chew toy - but she has only spent maybe two hours with it total.

Ex Output:

Negative
