Yes, there are several foods that are toxic to boxer dogs. It's important to be aware of these to keep your furry friend safe and healthy. Here are some common toxic foods to avoid:

1. **Chocolate**: Contains theobromine, which is toxic to dogs. Even small amounts can cause serious health issues.

2. **Grapes and Raisins**: These can cause kidney failure in dogs, and the exact reason is still unknown.

3. **Onions and Garlic**: Both can damage a dog's red blood cells, leading to anemia. This includes powdered forms as well.

4. **Avocado**: Contains persin, which can be harmful to dogs in large amounts.

5. **Xylitol**: A sugar substitute found in many sugar-free products, xylitol can cause a rapid insulin release, leading to hypoglycemia (low blood sugar) and liver failure.

6. **Alcohol**: Even small amounts can be dangerous, leading to vomiting, diarrhea, difficulty breathing, and even coma.

7. **Caffeine**: Similar to chocolate, caffeine can be toxic and lead to restlessness, rapid breathing, heart palpitations, and muscle tremors.

To keep your boxer safe, always check labels and avoid giving them table scraps or foods not specifically made for dogs. If you suspect your boxer has ingested something toxic, contact your veterinarian immediately.
