I've heard of people using them in the winter in areas that get tons of ice melt/salt, but only in problem areas or on dogs that already have issues (some dogs seem to have tougher feet than others).
I used booties for my old girl to protect her feet. She had severe HD and dragged her back left foot causing injury and bleeding. It took a while to get her acclimated to them even though she was very tolerant of things like that.
I would be surprised if a puppy would tolerate them. I can imagine a lot of bootie biting (the shoes, not the...umm...bootay). Also, pups are not the most coordinated animals--being a baby and all--so he might get tripped up and fall with them on.
My suggestion is to walk early in the morning or after sundown when it is cooler.
