The thing is, the Science Diet your buying now isn’t the same as it was when you started using it. Like you, I used Science Diet for all my dogs for many, many years. Dog food companies change their formulas for various reasons, mostly economical reasons. Science Diet changed their formula several times over the years that I used it. I fed my dogs twice a day, so it was very easy to tell when the food looked and smelled different. You can see some info on one of these changes here:

Be sure to read the entire article, including the updates.
I truly hope your dog’s “replacement” does fine with Science Diet. For me, I’ve learned my lesson and am still grieving the loss of my best friend.
