The reasons why puppy poop is particularly smelly:

1. It is caused by improper diet, constipation and other reasons. The feeding was relatively complex and they ate too many high-protein foods, meat foods or spicy foods.

2. Viral infectious diseases. It may be that the dog has not been vaccinated or the dog has not produced antibodies. Dietary factors or environmental factors have reduced the body's resistance and infected it with infectious diseases. Dogs may also have symptoms such as vomiting, diarrhea, and poor mental appetite.

3. It may be that the puppy’s gastrointestinal tract function is poor, resulting in indigestion and particularly smelly poop.

4. It is possible that the puppy’s dog food is not suitable for the puppy or the dog’s food is too much, causing indigestion and making the poop particularly smelly.

5. Parasites can also cause dog poop to be particularly smelly.

6. Too little exercise for dogs can also cause their poop to be particularly smelly.

7. Excessive use of meat will cause the dog’s own digestion ability to decrease, which will lead to a putrid smell in the feces.

8. Intestinal bleeding usually results in black stool or bloody stool, accompanied by a strong bloody smell. It needs to be taken to the pet hospital for further examination and treatment in time.

Solutions to the particularly smelly puppy poop:

1. Supplement the dog with probiotics. It can replenish the probiotics in the dog's intestines, increase the activity and quantity of beneficial bacteria, thereby enhancing the intestinal resistance and reducing the occurrence of diarrhea, constipation and stinky stools.
2. Let the dog maintain a certain amount of exercise. A dog's physique is not only determined by diet, daily exercise is also necessary. Dogs that exercise more are in good health, have high immunity, and their metabolic capacity will be maintained at a normal level. If their digestive system is healthy, their poop will naturally not smell bad.
3. Diet needs to be adjusted. Pay attention to replacing the dog food for elderly dogs with dog food that is more suitable for elderly dogs. It is softer and easier to absorb, which can effectively improve the dog's constipation and odor.
4. Take your dog for a checkup. If your dog is sick, smelly poop is one of the symptoms. Pay attention to taking timely measures. If it is serious, you should send to the doctor in time to avoid missing the best treatment period.
