Dogs can eat cooked oyster mushrooms. Oyster mushrooms are rich in vitamins and minerals. Feeding them in appropriate amounts can supplement relevant nutrients. At the same time, the crude fiber content in oyster mushrooms is relatively high, which can promote gastrointestinal motility in dogs and help relieve indigestion and other conditions.

Precautions for dogs eating oyster mushrooms:

1. Do not eat them raw. Oyster mushrooms are the most difficult to digest food. They must be chopped and cooked before feeding them to dogs. Never feed them raw.

2. Feed in moderation. Don't feed too many oyster mushrooms at one time, it's best to feed them little by little. You can also add some meat when feeding oyster mushrooms to make a reasonable meal.

3. Use dog food as the main food. It is best to feed your dog food specifically for pets to avoid discomfort. You can usually feed your dog vegetables such as Chinese cabbage, carrots, cauliflower, and broccoli.
