Daisy does the same..but now she's got too many toys to just focus on destroying one. Seems to work. I havent had a broken toy in a 2 months.
hehe
I've got the ''hide-a-squirrel'' toy and it seems to be holding up pretty well and then there's the 'plastic bone' toys with rope things hanging off it that she naws on alot and its been around for over 6 months.
If you're buying ''sqeaky toys'', look for ones that are made of a thicker, canvas-like material so that way it's harder for them to puncture and therefore longer lasting.
Hope this helps!
