Is the dog deworming collar useful (the harm of pet deworming collar)

Dog deworming collar can play a certain role in deworming, but it also has certain harm. The chemicals in the deworming collar can kill or prevent parasites such as fleas and ticks on pets. However, it should be noted that these drugs may have some side effects on pets themselves and human health. For pets, wearing insect-repellent collars for a long time may cause skin sensitivity, allergic reaction and even poisoning. For people, exposure to these drugs may also lead to allergies or other health problems. Therefore, before using the deworming collar, it is recommended to consult a veterinarian and read the instructions carefully to ensure the correct wearing and use of the deworming collar.
