Good investigation into the problem.

Wow, straight fish is the worst thing you can feed a dog ... right along with rabbit and deer.

Bitch might be ruined. Also, if this retard was feeding her raw catfish, be aware that one should never feed raw fish to a dog. Some kinds of fish carry parasites that are devastating to dogs (protozoa and worms), that affect blood and liver function, and a bottom-dwelling, scum-sucking species like a catfish would be the worst kind to feed raw to a dog.
