yes they can drive you nuts with them sometimes, mine really likes to squeak his when I am on the phone, just like a kid, LOL, but he really loves it and I wouldn't take it away.
Another prob is He likes to destroy them sometimes,(Learned from His Mother)and the squecky may make Him destroy it faster if His Mom doesn't? Still watching and prob bidding!
I don't know, mine with destroy a regular tennis ball, but hasn't destroyed the squeaky one, but they still might, never know, the squeaky ones give a little more, and squish, and the regular ones don't. maybe that is the difference,
Thanks :) He did enjoy it until my neighbor's dog (a Jack Russell) decided he wanted it for himself and stole it from Ripley :) LOL. So I'm hoping to replace it :)
