The reasons why golden retrievers are very thin:

1. Poor gastrointestinal absorption capacity. When a dog's gastrointestinal absorption ability is poor, the body's digestive enzymes to break down food are reduced, and nutrients cannot be absorbed, which will also make the dog lose weight.

2. Irregular diet. Irregular eating habits, excessive hunger and overfullness of dogs can lead to gastrointestinal problems.

3. Lack of exercise. Dogs that lack exercise for a long time are prone to getting sick, and their health and resistance will be slightly worse.

4. Unbalanced nutrition. If dogs are fed low-quality dog ​​food for a long time, they will not get enough nutrition. Not only will they grow longer and thinner, but they will also develop diseases.

5. Physical illness. When a dog is sick, his appetite will decrease, he will eat less, and the dog will slowly lose weight.

6. Infection with parasites. Internal parasites can also eat up a large amount of nutrients in the body, causing a lack of nutrients and weight loss in golden retrievers.

Care methods for very thin golden retrievers:

1. Regularly deworm. If there are too many parasites in the golden retriever, the parasites will compete for the nutrients in the golden retriever's body, and the owner must do a good job of regularly deworming the golden retriever.

2. Regulate the intestines and stomach. Do not feed your golden retriever anything that is difficult to digest or irritates the gastrointestinal tract. Occasionally, feed it some medicine to regulate the gastrointestinal tract.

3. Adequate nutrition. Golden retrievers are in the growth and development stage before 8 months. During this important period, the owner must ensure that the golden retriever's nutrition is sufficient.

4. Get enough exercise. Try to give it enough exercise every day to consume its excess energy, so that when it feels hungry, its appetite will be better.

5. Change dog food. Dog food is the staple food of golden retrievers. If you don't choose the right one, your golden retrievers will be picky eaters and thin.
