Query: Not so Tuff

Had I bought them for any other reason than to reach the $25 supersaver shipping requirement, I'd be pissed. As it is, oh well. My dog destroys tennis balls in minutes -- rips them along the seams. These were no different. In the time that it took me to go in the house to get the sunblock, the ball was torn. As for the smell, there was nothing whatsoever reminiscient of peanut butter. There was a very strong chemical smell, VERY strong, but not even a hint of peanut-y goodness. I didn't go so far as to chew on it, so I can't say that it didn't taste of peanut butter...but it seems highly unlikely. I agree with another reviewer that the Penn tennis balls seem to last a bit longer, and I can often find these at the dollar store, in packs of three.
