How to deal with fleas on puppies:

1. Spray anthelmintics. Use dog-specific repellent lotion or powder and spray it on your dog's body, including around its belly, paws and butt.

2. Use a flea comb. You can use a special flea comb to comb the puppy's hair from top to bottom close to the puppy's skin. The fleas removed by the comb will be eliminated by drowning them in boiling water or soapy water.

3. Send to hospital for treatment. If common methods cannot remove fleas, you should send them to the pet hospital immediately for reasonable and effective treatment.

4. Regular disinfection. The food bowls, mats, toys and other items that puppies usually use for eating should be washed and dried frequently, and the environment at home should also be kept dry and tidy.

Causes of fleas on dogs:

1. Improper breeding environment. When dogs live in a dirty or humid environment, it is easy for dogs to become infected with fleas.

2. There is no regular deworming. If the owner does not deworm the dog regularly, fleas will attach to the dog's body.

3. Infected by animals. Fleas can be spread to other pets by hopping, and dogs can become infected when they play with a flea-infested dog.
