Your dog has fleas, either by symptoms, flea filth, or visual fleas. The best home flea cures are:
High-pH apple cider vinegar repels fleas. It may kill fleas by drinking or putting it on your dog's coat.
Lauric acid in coconut oil kills fleas. Fat suffocates the flea's exoskeleton.
Dog-safe essential oils like lavender or peppermint may naturally kill fleas and their larvae. These oils deter fleas.
Citrus repels fleas just like vinegar. It's fantastic on dogs and around the house.

In the yard, try this pest-control method. Flea larvae are eaten by soil-dwelling nematodes.
Diatomaceous earth kills fleas in your house, not your dog, it kills fleas by sucking moisture.
Another approach for your house, not your dog. Baking soda and salt dehydrate fleas and flea eggs.
