Foods that are dangerous for dogs:

1. Soy products: Dogs eating tofu and other soy products can cause stomach swelling. Avoid tofu or other soy products as a food source for dogs, especially dogs with thick chests such as Great Danes. These foods stimulate mucus secretion and can easily cause stomach swelling, which can be life-threatening.

2. Milk: Dogs eating milk can cause diarrhea. Puppies can secrete an enzyme that helps puppies digest milk. But adult dogs can only secrete a very small amount of enzymes, which are not enough to help digest milk, so milk can easily cause bloating in dogs.

3. Sweets: Dogs eating sweets can lead to obesity. Sweets, sugar and other sweet foods can easily lead to obesity, insufficient calcium absorption and dental caries, and it is not good for dogs if they cannot break down sugar on their own.

4. Bones: Dogs eating bones can cause gastrointestinal scratches. Chewing bones is the most common cause of broken teeth in dogs.

5. Onions: Dogs eating onions can cause poisoning and death. Eating too much onions can easily cause poisoning. Symptoms include dark brown hematuria and dysentery and vomiting within one or two days after eating. Special attention should be paid to this.

6. Others: Don’t feed too much fresh vegetables and fruits. Seasonings such as pepper, chili pepper, mustard, mustard seeds, and ginger will affect the dog’s olfactory sensitivity, so you must not feed it.
