Yes, there are certain human foods that can be toxic or dangerous for Rottweilers to eat. It is important to keep in mind that while some human foods may be safe for humans to eat, they may not be safe for dogs. Here are a few examples of human foods that can be toxic or dangerous for Rottweilers to eat:

1. Chocolate: Chocolate contains a substance called theobromine, which is toxic to dogs. The amount of theobromine that is toxic to dogs depends on the size of the dog and the type of chocolate that was ingested. Dark chocolate and unsweetened baking chocolate contain higher amounts of theobromine than milk chocolate and can be more toxic to dogs.
2. Grapes and raisins: Grapes and raisins can cause kidney failure in dogs. Even small amounts can be toxic, and it is not clear why some dogs are more sensitive to the toxic effects of grapes and raisins than others.
3. Onions and garlic: Onions and garlic contain compounds that can damage dogs’ red blood cells, leading to anemia. These compounds are found in all forms of onions and garlic, including powdered, raw, cooked, and dehydrated.
4. Macadamia nuts: Macadamia nuts can cause tremors, hyperthermia, and lethargy in dogs. The exact toxic component of macadamia nuts is unknown, and it is not clear why some dogs are more sensitive to the toxic effects of macadamia nuts than others.
5. Avocado: Avocado contains persin, which can cause vomiting and diarrhea in dogs. The leaves, fruit, seeds, and bark of the avocado tree are all toxic to dogs.

It is important to keep these and other toxic foods away from your Rottweiler and to consult with a veterinarian if you suspect that your dog has ingested something toxic.
