The blue ice alternative is just another chemical for snow melt - a few people around here do use it and i try to avoid all of those things on our walks (impossible to avoid completely unless i carried the boys the whole walk!) but i would definately stop milo from trying to lick it off, and especially if it is windshield wiper fluid as that has antifreeze in it which is toxic... but the chances that a neighbor was using liquid windsheild wiper fluid to melt his ice is slim. unless he is
I have used the pet safe ice melter- it is effective, maybe not quite as much as the harsher chemicals but almost. I would shop around to see if you can find it cheaper, if you are taking about the little plastic container with a handle ( i think it is only 2 lbs or so) I have seen it in petstores (petco and petsmart) for $11 but in places like Bed bath and Beyond and a few other non pet store places for as litte as $6.99 - check around and see if you can find it cheaper- but yes it works and doesn't seem to bother the feet.
