    "Great Multi-Purpose Med."

    I love this stuff and keep it on-hand at all times. I use it to orally worm my livestock; orally to keep my dogs and cats parasite-free; topically when ear mites are suspected. This is a great, multi-purpose, and inexpensive wormer to use.

    "Works great"

    I have dobermans and have used this for over 2 years. My dogs are all 60#+. I use 1ml per dog. Have never had a problem with any of them. Each year there tests are clear. This is the most economical way to go when you have several dogs. I do rescue so the # of dogs I have varies. Sure saves money over buying from the vet. Plus it takes care of other parasites. And Jeffers has the best price. Love this company..

    "Dogs, Goats, Sheep, Chickens"

    I have been using ivomec for YEARS as a heartworm preventative for all my dogs ranging from toy poodles to Dobermans. I also use on goats and sheep and even for my chickens as a dewormer. Its mild enough to use on pregnant does. EA- I read your post on Ivomec doseage. Ive been using it at a 10th of a cc per 10 pounds for dogs and never had a problem. Not sure why your dog got sick at that doseage (I do know it is not safe for collies). I got the doesage for dogs from my vet. For goats I use orally at 1 cc per 40 pounds. Chickens- one drop in mouth per chicken.

    "Many people are overdosing their pets."

    I have been giving my 45+ pound dogs 0.1cc for over 20 years. I found out this is too much! The vet told me to give them 0.01 cc for a 45 pound dog. Please note that is 1/10th of 1/10th of a cc. I was an idiot and gave my 70# dog 0.7 based on the customer reviews. She was throwing up for 2 days and is still not eating much. I am hoping I did not permanently hurt her. Fortunately, my other dogs seem okay. My vet is opposed to Ivermectin for this very reason. Do your research before you give this to your pet. My dogs have not had problems in over 20 years with 0.1 cc, so please lower our dose!

    "Use on wild red fox to treat mange"

    I use this product as oral treatment for red fox. It's hard to control which fox gets each dose, but I have had success dosing pieces of chicken. I inject .2 mL for each dose every three days for 3 weeks, then every 5 days for 2 more weeks.

    "use in rabbits"

    You can use this in rabbits. That is the correct dosage for use in rabbits or guinea pigs. It works wonders for mites and lice. I have used this product at that level for twenty one years.

    "Most economical heartworm preventative for dogs!"

    According to my vet, the correct dose for dogs is 1/10th of a cc (or ml) PER 11 lbs of dog's weight. I have used this method of heartworm preventative every month for ten years with 100% success. The dose for the rabbit sounds like a HUGE OVERDOSE. a 5 LB rabbit would only need 1/20th of a ml or cc. if this is even an appropriate medication for rabbits. It is TOXIC to cats and should never be given to them.

    "Check Dosage"

    Being part of a dog rescue group and many dogs going thru our rescue we use this as the monthly heart worm treatment for the dogs, including my personal dogs under Vet supervision. HOWEVER: The dosage is 0.1 ml per 10 lbs or 1/10th of a cc per 10 lbs that is a 50 lb dog would get 1/2 a ml. or 0.5 cc.

    "check dosage"

    Correction: 1/10 of a ml per lb. for a rabbit given once then repeat in 7 days. Sorry for the confusion.

  10. 5.0 out of 5 stars


    Rose, that seems awfully high for a rabbit. For dogs, it's only .01cc per pound! My *100 lb* dog gets 1cc! Please, everyone, check your math. You can kill or cause serious liver damage with an overdose.

    "saved my rabbit"

    Though not labeled -Given orally saved my rabbit from Encephalitozoon cuniculi. Can also be used for fur mites. Orally at the rate of 1 ml per lb. Great product!

  12. 5.0 out of 5 stars


    I have used this product for a long time. When ordering just becareful you are ordering the wormer and not the gun. I just made this mistake. OUCH!

    "Works Great"

    This is a great product. And the price is the lowest I've found from any vendor. While it doesn't kill every parasite, it kills 90% of what are a problem in my area. I would definitely recommend this product to anyone who has livestock. It is a thicker suspension so you need to use a larger gage needle for it.
