Output: positive


Input: Consider Input: I have very hard water where I live. I use this once or twice a week and it really helps remove the build up on my hair. I'll definitely keep using this.

Output: positive


Input: Consider Input: Overall I was pretty displeased with this toy. I got it for my Police K9 so I expect toys to not last as long as they would for a normal drive dog. That being said I noticed problems before the dog even saw the ball. For one, they use a metal washer to keep the string tied onto the ball. Be sure to remove that first before you give it to your dog or run the risk that your dog cracks a tooth and undergoes a painful (and pricy) surgery to have that corrected. When I took out the washer I double and eventually triple knotted the knot at the bottom to keep it in the ball. The dog just has to pull a little and the string pulls right through the ball and you have no handle on your dog or the toy.


Output: negative
