They were, well, tennis ball shaped, and tennis ball covered, and had paws on it, as dog-intended tennis balls so often do. What really caught my eye, though was that they were "mint". I was fascinated, skeptical, and happy all at once.
Out of the bag, the "Spot" mint tennis balls don't smell minty at all. Rather, they smell very rubbery. I asked Elka if they smelled minty to her, but as we don't yet have a "tap once for yes, twice for know" sort of setup, she just kind of looked at me, and then took the ball. They also do not bounce; if you drop one from about shoulder height, it does a single rebound of perhaps three inches and then lays where it falls.
Elka, as always, was a concentrated and dedicated participant. She took each ball readily, and set tooth to it. The first one, I wasn't quite paying the best attention to how long she had it. The second one, I said the time (11:28) when I handed it to her. It was but four minutes later, 11:32, when I removed the sad carcass from her jaws.
So, while interesting in its minty-non-minty nature, 8 total minutes of playtime is a sad followup to some of the contenders we've auditioned.
