If the dog is sick and refuses to drink water, the owner can put the dog food in the water when feeding the dog, soak it until it softens and then feed it to the dog. This can not only replenish the dog's water, but also help the dog's digestion when it is sick and has a bad gastrointestinal condition. If necessary, the dog can be injected with rehydration fluid to help the dog replenish body water and prevent the dog from becoming dehydrated.

How to take care of a sick dog:

1. Prepare a comfortable resting environment for the dog. You can arrange a resting corner for the dog, and put the dog's favorite mats, the owner's clothes, the dog's favorite toys and other things in the corner that make the dog feel at ease.

2. Make sure the dog has enough clean drinking water. Water can help the dog excrete harmful substances from the body. If your dog doesn’t eat well, you can feed it some glucose water or chicken soup.

3. Eat small and frequent meals every day, and let the dog eat some easy-to-digest food. You can add some chicken or chicken soup to the food to increase the dog's appetite.

4. When the dog can move, take it out for a walk. Proper exercise is good for the dog's health.
