There are many reasons why dogs lose weight after deworming. First of all, insect repellent may cause some side effects, such as loss of appetite and digestive system disorder, which will affect the dog's food intake and nutrient absorption. Secondly, the existence of parasites in the body usually has a certain impact on the health of dogs, including affecting the function of digestive system and consuming nutrients, so the recovery of parasites takes time. Finally, deworming is only a part of maintaining the dog's health. We should pay attention to the comprehensive management of diet and exercise to maintain a healthy weight.

If the dog loses weight obviously after taking the insect repellent, it is recommended to take it to the pet hospital for symptomatic treatment in time. In addition, pay attention to strengthen the dog's nutrition intake and exercise, especially to ensure the supply of protein, vitamins, trace elements and other nutrients, and help the dog to restore healthy weight smoothly. At the same time, we can consider adding some auxiliary conditioning foods, such as nutritional supplements and diet products, to improve the immunity and physical rehabilitation of dogs.

In short, it is common for dogs to lose weight after deworming, but attention should be paid to mastering appropriate treatment methods and feeding skills to help pets regain healthy weight and maintain a healthy life.
