Blue Seal makes their own feed at their own mills, as does Kent. The companies merged but the mills stayed separate. Each has their own recipes and have not changed. Both are good feeds, I have fed Blue Seal all my life for the horses, dogs, cats, chickens, goats, cattle, rabbits, etc...... I used to feed one of the Kent dog foods until they got greedy and took the dealership from Blue Seal (who was making the food) last fall. No warning at all, and at the beginning of training season. Suddenly no one could get it around here. Messed up the dogs condition. Then my dealer managed to get it thru another supplier...at 12.00 a bag more expensive! Now he can't get it at all because the supplier will not sell just a few bags. Kent is no help at all. I don't care how good their food is, I refuse to do any business with them now.
