It depends on HOW small you are looking at. I have seen some lines that tended to throw small hedgehogs, around 300 grams in weight or just under. They typically were just fine as far as health goes, however, sometimes some of the really small ones have a tough time if there is a major illness show up, because they don\'t have a lot of reserves built up. I have also seen what is referred to as \"failure to thrive\" hedgehogs, who stay small and never seem to grow properly. These tend to be pretty weak, and die young. I had one hedgehog who actually had some form of dwarfism, she was adorable, but tiny, with some slightly odd physical characteristics. She did OK, but didn\'t live really long, and I never bred her because A.) I didn\'t know what health issues she could have and B.) She was so small any male I owned would have squished her.
