Repairing a pair of glasses?

I wanted to know is there any way to repair the plastic ends of the frames that rest above your ear? My dog unfortunately chewed off one of them and now just the metal frame is exposed.Repairing a pair of glasses?
Home depot sells plastkote which is like a glue and is mean to coat tools. It is available in black. Try that. Otherwise you need to replace the arms (if that is what they are called) of the glasses... buy a cheap pair of sunglasses and use it from there.
Buying an arm of the glasses is not that expensive.
