After last week's Chuckit! testing we acquired a couple of new balls to try. "Erratic Ball" and "The Whistler" are the two that we took for a spin today at the dog park.
Xena rates them both Excellent for playability. They both fit nicely into the Chuckit! launcher and are easy to pick up without bending over. I was able to throw each ball farther than the conventional tennis ball-like Chuckit! ball. The Whistler did indeed whistle although I think this fact was lost on Xena. The Erratic Ball did bounce in an unpredictable fashion and I think this made for more interesting retrieving. All in all I think we will use both of these new balls more often.
As for durability I would rate these Good to Excellent with normal play. They are both made of soft rubber but held up better than the conventional Chuckit! ball which was showing wear after a dozen or so throws. However, Wes the Labrador was not at the dog park today to put the new balls to the heavy-chewer test.
Safety-wise both The Whistler and Erratic Ball rate a Good if used properly. They are both hollow and so could probably be chewed to bits if a dog was left unattended with them. As previously noted, the Chuckit! launcher and the balls are interactive toys meant for supervised play only.
