The dog food thing is such a headache.
Really it depends on what your dog does best on and how Comfortable You are with the company.
Yes... TOTW is Diamond. My sis fed it not even realizing it was a Diamond Product. They then took all of it off of the shelves for a couple of months, last year. She hasn't fed it since.
Diamond was involved in the recalls in back in 2006.. [of 19 varieties...] which killed Dozens of dogs.

A co-worker of mine had a miniature pincsher that died because of it... it was a nasty slow sad death...
I'm not sure if 2006 and 2012 were the only two year they had recalls, or if there have been more??
Just knowing someone who went through that made me decide I personally would never feed anything having to do with Diamond.
