1. **Chocolate**: Contains theobromine, which is highly toxic to dogs. Even small amounts can cause symptoms like vomiting, diarrhea, and increased heart rate.
2. **Grapes and Raisins**: These can lead to kidney failure in dogs, and even small quantities can be dangerous.
3. **Onions and Garlic**: These can damage red blood cells and lead to anemia. Symptoms may include weakness, lethargy, and dark urine.
4. **Avocado**: Contains persin, which can be harmful to dogs in large amounts. It's best to keep this away from your boxer.
5. **Xylitol**: A common sugar substitute found in many sugar-free products, xylitol can cause a rapid insulin release leading to hypoglycemia (low blood sugar) in dogs.
6. **Alcohol**: Even small amounts can be dangerous, leading to intoxication, coma, or even death.
7. **Caffeine**: Similar to chocolate, caffeine can be toxic and lead to restlessness, rapid breathing, and heart palpitations.
8. **Macadamia Nuts**: These can cause weakness, depression, vomiting, and tremors in dogs.
9. **Yeast Dough**: If ingested, it can expand in the stomach and cause painful bloating or even rupture.
Always consult your veterinarian if you suspect your boxer has ingested any toxic food. It's also a good idea to keep these foods out of reach and educate family members about what is safe for your furry friend.
