It is useless to bathe your dog if he has fleas. Bathing a dog can only remove dirt on the body, but cannot completely remove fleas from the dog. To get rid of fleas, use deworming medication on your dog. If there are few fleas on your dog, you can apply anthelmintics on the dog's head or neck to kill the fleas. If there are many fleas on the dog, you can use an insect repellent spray and spray it all over the dog. Be careful to avoid the dog's eyes to eliminate the fleas on the dog.
Precautions for removing fleas on dogs:

1. After using deworming medicine on your dog, you can only give it a bath after a week to avoid affecting the effectiveness of the medicine.
2. You can wear a flea-repelling collar on your dog. The drug will gradually be emitted and can effectively kill fleas.
3. If you don’t want to use medicine to remove fleas on your dog, you can use a fine-toothed comb to comb the dog’s hair. After combing out the fleas, put them in boiling water and scald them to death.

4. Do not blindly use folk remedies to remove fleas on dogs, so as not to endanger the health of the dog.
