My Nazz is about 5 1/2 months and has extra toes on her back feet. They haven't been a problem but I've notice that the one is always under her foot. Do you think that is uncomforable to her to be walking on her toe? I mean, when I pick her up its like stuck umder her foot. She walks fine and plays and all. My friend told me to just tie a string around the extra toes, but I'm a little afraid I might hurt her. Help.
