Hi Mary –
Of the foods you mentioned I believe Orijen is the best choice. I would never feed TOTW as it’s manufactured by Diamond. Fromm is a great company but the food is really overpriced for the quality and not worth the expense (imo). I wouldn’t stick with one food though. Rotating foods often will keep your dogs interested and will also strengthen their digestive system. If they prefer canned and you can afford to feed only canned this is actually preferable to feeding dry food – canned food is more species-appropriate than dry food due to the fact that it’s less processed, high in moisture and higher in protein. Most dogs also find dehdyrated or freeze-dried (both of which you rehydrate prior to feeding) and raw foods more palatable than dry food – these options are healthier than dry food as well. For the loose stools try adding a spoonful of plain canned pumpkin and a probiotic supplement to their meals, this may help.
