What Can You Put on Puppies for Mosquitoes?

Choose from natural, homemade or chemical products to protect your puppy from mosquitoes. Young puppies are sensitive to some products, so test any product and observe the puppy's reaction for 24 hours after application. Always check the package for the age it's safe to apply, and never use a product containing DEET on a puppy or grown dog.

  1. Home Treatments

    • A mixture of apple cider vinegar and water is safe and effective against mosquitoes, as well as easy and inexpensive to make at home.

      Mix one part apple cider vinegar to three parts water. Put the liquid in a spray bottle and lightly spritz your puppy. Use a small amount to start, then rub or brush it through the puppy's coat. Use this mixture daily or weekly as needed.

      Mix cedarwood oil with water in a 1-to-10 formula, or tea tree oil with water in a 1-to-3 formula, sprayed lightly on the puppy. use these with caution on young puppies, however, using very little at first.

    Chemical Protection

    • Protect your puppy when he's outdoors.

      You can buy numerous chemical products that repel mosquitoes, but read the packaging carefully because most are not safe for puppies under 12 old. Some may cause side effects. Ask your vet to recommend the correct chemical repellent for your puppy if you decide to purchase one.

      These products are spot-on liquids applied between the pet's shoulder blades, and they are effective for 30 days. Some are waterproof.

    Natural Choices

    • You can buy a number of natural formulas available from pet stores in a spot-on treatment. Most contain ingredients such as peppermint, cinnamon, lemongrass and thyme oils. They are generally effective for 30 days but are not waterproof.

      You also can buy spray formulas with the same ingredients for shorter-term use.

    Other Safeguards

    • Ask your vet about heartworm medication for your puppy.

      Your vet will determine the proper time to begin treating your puppy with heartworm medication. Heartworm is a serious, mosquito-borne illness that can kill adult dogs and puppies. Prevent it by administering a monthly pill obtained by prescription from your vet. Most vets recommend year-round medication; others suggest using the pills only during the mosquito season. Get regular heartworm tests for your puppy if you don't treat year-round.

      The ASPCA recommends taking precautions to avoid mosquitoes by removing standing water around your house and keeping puppies inside at dawn and dusk when mosquitoes are most active.

      Carefully observe your puppy when using any treatment, natural or chemical, for adverse reactions. Call your vet if you notice any sign of lethargy, stomach upset, weakness or seizures.
