How to Split Frontline Doses
Splitting large doses of Frontline can save money. (dog image by Ramona smiers from

Frontline is a flea and tick preventive treatment that is applied to dogs and cats. While it is available in small, single-use doses, you can also buy it in larger doses intended for larger dog breeds. The larger syringes can be split into smaller doses and applied to small dogs and cats. Because the per-dose cost is cheaper for the larger containers, pet owners will save money on Frontline treatments.

  1. 1

    Go to the pet store and locate a package of Frontline for the size pet that you have. Frontline for cats is available in only one size, but Frontline for Dogs comes in various sizes based on the weight of the dog.

  2. 2

    Check the package's ingredients panel to determine how much liquid, in ml, is in each dose for your pet. Make a note of this number. You will need it later.

  3. 3

    Purchase the largest dosage of Frontline that you can find, for very large dog breeds.

  4. 4

    Open the container of Frontline and squeeze all of the liquid into a glass vial or bottle.

  5. 5

    Push the plunger all the way into the needle-less syringe and place the tip of the syringe into the Frontline solution. Pull back on the syringe until the fluid line reaches the dosage, in ml, that you determined in Step 2.

  6. 6

    Remove the syringe from the solution and place the tip on the back of your pet's neck. Press down on the plunger until all of the Frontline fluid is dispensed onto your pet.

  7. 7

    Place the airtight cap on the bottle or vial and store the unused Frontline into a cool, dry location until it is time to apply another treatment.
