How to Use Apple Cider Vinegar for Fleas on Dogs?

The entire method of using this homemade flea repellent can be divided into two phases. The first one of them is the precautionary phase in which you ensure that your dog won’t be harmed. The second phase is the process of applying the solution. Let’s discuss both of them to make things easier for you.

Precautions before Applying Apple Cider Vinegar

Once you have prepared the apple cider vinegar remedy, it’s important to use it without harming your pooch. Therefore, you must observe a little bit of caution and ensure that the spray never goes into your dog’s eyes, nose, and ears. Similarly, check your dog carefully to find any open wounds because vinegar stings on damaged skin. If there are such wounds, make sure to cover them while spraying to avoid the discomfort (to your dog).

Application of Apple Cider Vinegar Flea Repellent

  • Spray the mixture directly over your dog’s coat and rub it (with your hands) so that it could reach the skin.  
  • Give special attention to the neck, armpits, and groin area because fleas like to hide in these spots.
  • Allow the vinegar solution to dry. It will take around 15-20 minutes.
  • Now, use a flea comb to brush away the fleas from your dog’s fur.
  • You will need to repeat this exercise every couple of days until the comb stays clean (after brushing).

Other than that, you can also make an apple cider vinegar solution with equal parts of water and vinegar and spray it around the house. For example, furniture and carpets are ideal locations for fleas to hide. Spraying this mixture can be helpful to prevent a re-infestation due to these hidden parasites. Your pet’s bedding is another spot that must be sprayed with apple cider vinegar to keep fleas away.

How Often Should I Spray My Dog with Apple Cider Vinegar for Fleas?

The general rule of thumb is to spray your dog once or twice a week. The exact frequency will depend upon the severity of the infestation. Apple Cider Vinegar doesn’t kill fleas but can keep them away from your pooch because of its nasty smell. However, you will need to apply it regularly to get the desired results, especially if you have fleas in other places, like carpets and furniture.

This is because these pesky parasites are always looking for an animal host and would jump onto your pup. Likewise, they could be hiding on your dog’s coat (and bedding) and repeated sprays of apple cider vinegar will ensure that they are removed. Make sure that the vinegar reaches down into your dog’s skin to eliminate the maximum number of fleas.

Is Apple Cider Vinegar Safe for Dogs to Consume?

Large quantities of apple cider vinegar can be harmful to your pooch. The acid in the vinegar can damage the lining of the dog’s digestive tract. Similarly, it can cause wear and tear to the enamel of your canine’s teeth. However, spraying a dilute solution of apple cider vinegar on dogs is completely safe and won’t cause any trouble, even if consumed.

Some people believe that adding a teaspoon of this vinegar to your dog’s food can be beneficial. However, there isn’t enough research to back these claims. Therefore, it’s highly recommended to consult your veterinarian before introducing apple cider vinegar into your pup’s diet.
