It's not really common, no. Bloat is mostly a concern with large-extra large breeds. Huskies should only be considered a medium breed, maybe large breed (properly bred huskies that is).
Bloat is caused by excitement or exercise immediately before or after meals, which should honestly be monitored anyway. However, it's not such a dangerous concern for huskies as it would be for a great dane for example.
