To prevent dog parasites, you can use a comb or bath

Magic water and comb. For small-scale parasite damage, you only need to bathe your dog frequently and insist on using a lice removal comb. Taking a bath can drown fleas, and you can even eliminate the need for chemicals. Natural plant flea removers or shampoos can prevent parasites while also conditioning your pet's skin. For dogs that love to be active outside, no matter how long their hair is, bathe them once a week during flea season, and use a fine-tooth comb to comb every inch of hair during grooming.

The teeth of the flea comb are particularly closely spaced, so fleas can be picked out from between the hairs. In addition to weekly bathing, combing the entire body with a flea comb every day can keep many dogs away from fleas. If more than one or two fleas appear every day and last for more than a week; or if your dog is very sensitive to flea bites, it is time to consider using a chemical flea killer.

Methods to remove parasites from dogs

1. Put the dog in the bathtub to bathe. Fill a basin with water. Don't let the water drain out. Clean the hair carefully and get deep into the skin, especially the ears, tail and belly, where fleas are concentrated.
2. Let the dog sit in the tub so that you can drown the fleas around the tail while you comb other parts of the hair.
3. Rinse the hair completely for 5 minutes, then spray it with a hand-held sprayer or pour water on the body with a cup. (Plug the ears with cotton balls to prevent water from entering when flushing, or hold the ears and fold them over to cover.)
4. Dry as usual.
5. Finally, use a lice removal comb or a comb of appropriate size to slowly comb from the tail to the head. Make sure to comb deep into the skin each time.
6. If fleas, flea excrement, and flea eggs are still present, find them. Apply a small amount of alcohol and rinse clean after all is resolved. Because their shells are hard, they may not be crushed with your fingers. (You don’t really want to crush them to death with your hands, do you? )

7. If no fleas are found after a thorough cleaning, that's great. Treat daily with a flea-killing comb and bathe once a week to keep fleas at bay.
