&$#*^% dog! Help!

[SabrinaJL]

I was knitting a sock on size 2 bamboo DPN's and the dog managed to get her rotten little puppy teeth on it (that'll teach me to leave things in her reach). The sock is easily fixable but the needles didn't fare so well. One of the ends is chewed badly and I can't even FIND the other one. So now I only have 3 size 2's. Can I use one in a different size or will that screw the whole thing up?
