Apple cider vinegar is a useful ingredient to keep fleas away from your pet. Although it can’t kill these external parasites, this type of vinegar is quite effective to repel them away. This is because fleas don’t like the taste and smell of this vinegar and will prefer to stay away. However, some adult fleas may choose to stick with your canine friend (even after the spray of this vinegar) if they can’t find another host.

The most common method of application is spraying the mixture of this vinegar and water on your pup. If your dog doesn’t enjoy this feeling, you can use a comb/brush to apply the mixture. Dip the comb in the mixture and brush the fur of your canine friend. This will distribute the apple cider vinegar mixture on your pooch’s hair and body.
