Biting Christmas lights?

Last year I had a problem with my little one biting Christmas lights at the bottom of the tree. I used some deterrant spray from Target, which seemed to work okay....for a few minutes. Finally, I had to resort to making a large barrier out of an old refrigerator box, so he couldn't get near the tree at all. Let's just say it wasn't the most happy of holidays. :(

I'm about to put this year's tree up, and I don't want to have the same problem. Does anyone have those LED lights that say they are "break resistant"? Do you think that would be a good solution for this problem? I can't think of anything else, short of not putting lights far enough down for him to reach.

Any suggestions?

I don't have any suggestions but if anyone else has clues, I'd like to know, too. We didn't put up a tree last year. This year, Doogie sometimes likes to chew on the cords. Wonder how he'd look with curly hair?

This is an easy one! Tree goes in a playpen! Then you can have lights and decorations all the way down, and presents can be tucked under, too, without anyone being able to chew them! We put a playpen around the tree when we had Gracie the Great Dane mix. She had no idea where her tail was at any given moment, so everything tail-high and below (more than half the tree) was otherwise denuded if Gracie was happy and in the living room.
