Since Flea & Tick season is up on us thought I would copy this from Dog Fancy so all can read their say on some of this.Also article about feeding raw in there Natural Dog section on this months magazine.
I always shake my head at people who give their dogs things and dont worry because after all it can't hurt them, it's "natural". It's good to be informed thanks for this list.
