Flea and Tick Medication Redosing Charts
Flea and Tick meds are expensive yet a dose for a 10 lb dog costs the same as a dose for an 80lbs dog! The charts below will help you to break down dosages for small dogs after purchasing the package for large dogs. This will allow you to treat several dogs for the price of 1.
The best way I have found to do this with the liquid medications is to use a 3ml syringe to measure the dose from the large dog vial. When finished , draw the remainder into the syringe, put a cap on it with the dose amount written on attached piece of paper for future reference then store it in the refrigerator.
Links to each of the products are also listed above each chart for reference
Advantage & Advantage II (Imidacloprid)
Advantage required adult fleas to ingest the medication, at which point they would be impacted by the insect-specific neurotoxins and die. Advantage II kills fleas on contact, with the addition of three new chemicals to its formula, that makes your dog or cat’s skin an entirely inhospitable environment for pests. Eggs are killed before they hatch. Adult fleas are killed and will fall off, or will be washed off in your dog’s next bath.
Dose is 0.05ml/pound. Multiply 0.05 times your pet’s weight for the dose

(Package instructions) (Used in lower doses with same effect)
Cats 1-10 pounds – 0.5ml 0.3ml for 10lbs 0.45 for 15lbs
Dogs 11-22 pounds – 0.67ml 0.6ml for 20lbs 0.75 for 25lbs
Dogs 23-44 pounds – 1.34ml 0.9ml for 30lbs 1.5 for 50 lbs

Dogs 89-132 pounds – 4.0ml 2.7ml for 90lbs 4.0 for 133lbs
NOTE: If you’re using Frontline Plus —
The amount of fipronil in the dog version is the same as in the cat version. The “Plus” is methoprene, an insect growth regulator. There’s LESS of it in the dog product than in the cat product, so it’s safe to use the dog product on the cats but do NOT use the cat product on a small dog.
Generic Frontline Plus for dogs may contain a different ingredient than the brand name. If a generic Frontline product contains something other than methoprene or fipronil it may not be safe on your cat.

Revolution (selamectin)
Revolution® has a single active, safe in both cat and dog, but it’s concentration varies: the formulation for puppies, kittens and cat is half strength. If splitting a large dog vial and applying the volume stated on the packaging for a cat, a double dose would be given. Take careful note of the half volumes shown below (concentration: 60mg/ml vs 120 mg/ml). Product Insert
(based on 120mg per 1ml potency. Dose is 0.025ml/pound. Multiply 0.025 times your pet’s weight for dose.)
0.0-5lb dog/ cat = 0.12 ml
5.1-10lb dog/cat = 0.25 ml
10.1-20lb dog/cat = 0.5 ml
20.1-40b dog = 1.0 ml
40.1-85lb dog = 2.0 ml
85.1-130lb dog = 3.0 ml
(based on 60mg per 1ml potency. Dose is 0.05ml/pound. Multiply 0.05 times your pet’s weight for dose.)
Up to 5lb cat/dog = 0.25ml
5.1-15lb cat = 0.75ml

*dosage is approximate my math calculations came out to be 0.05ml/lb, but there is a discrepancy with packaged dosages. Also there is more Moxidectin in the dog formula than in the cat formula, so I would not put dog product on cats*
Advantix®
NEVER USE THIS ON CATS. If you get Advantix® on your hands when splitting a vial for the dogs, do not touch your cat before thoroughly washing your hands with warm soapy water. Advantix causes permethrin toxicity in cats because they cannot metabolize the permethrin in Advantix.
0-10 lbs = 0.4ml 41-50 lbs = 2.0ml
11-20 lbs = 0.8ml 51-60 lbs = 2.4ml
21-30 lbs = 1.2ml 61-70 lbs = 2.8ml
31-40 lbs = 1.6ml 71-80 lbs = 3.2ml

Flea Allergic pets, like those of us allergic to mosquito bites, will incessantly itch and pull out all their hair if just one flea gets past the flea control. Given most spot on agents only achieve high kill rates, above 95%, for the first 2 weeks of the month, twice monthly application is often recommended by dermatologists when treating flea allergy.
