Golden retrievers can drink soy milk. Soy milk contains a large amount of protein, vitamins, trace elements and other nutrients, which can effectively supplement the dog's body's demand for nutrients. However, dogs have poor digestion of plant-based protein. Consuming too much soy milk can easily cause digestive tract abnormalities in dogs, leading to vomiting, diarrhea and other symptoms.

Precautions for golden retrievers to drink soy milk:

1. Consume in small amounts. Do not feed too much soy milk, as it may cause vomiting and diarrhea in dogs.

2. Do not drink soy milk for weak dogs. The gastrointestinal system of puppies is very fragile, and the gastrointestinal system of dogs with poor physical fitness cannot tolerate drinking soy milk, which will cause diarrhea.

3. No added sugar. Sugar cannot be added when feeding soy milk to dogs because the dog's body cannot digest and break down sugar, which can cause gastrointestinal discomfort and vomiting or diarrhea.
