Ivomec for Dogs

June 14, 2017 Wednesday

The Shaggy Lady has gotten tapeworms. Ugh. I kind of suspected something was up since she's had a bit of tummy trouble, but until now no proper signs to confirm anything. Neither me nor the vet saw a point in running tests when she was happily bouncing all over the place and feeling fine. No, we haven't been deworming the dogs regularly because all the stuff the vet offers is $50+ a month for them. It's hard enough geting up the $25 for me to go to the doctor every six months. Before anybody complains about "adopting a dog you can't afford", maybe people should stop dumping fertile dogs off in the country! Our two pups came from an abandoned female and the shelters are full. I'm not in the habit of killing healthy animals who've done no harm, so we got two new members of the family with the same level of limited care their owners have to have.

I don't know why, but I completely forgot about Ivomec. When I was a kid, we used Ivomec on every furry varmint that was in our care. They were pretty dang healthy. The cats lived to be 17 and 18. The dogs never did do well. One hiked the half mile to get hit by a car, cancer got two, coyotes got another, one just vanished, and other various things. But none were related to parasites!

Ivermectin is the active ingredient in Ivomec, and is meant to control skin parasites and gastrointestinal parasites in cattle and swine. I think the cat and dog version is called Heartgard. So that's fleas, ticks, mites, lice, and worms, including round worm, hook worm, tapeworms, lungworms, and heartworm. In my experience, it takes care of the innards and you still have to routinely treat them for fleas and ticks.

Oral General Wormer with Ivomec/Ivermectin 1%
110 cc per 10 lbs of dog's weight
Oral Heartworm Prevention with Ivomec/Ivermectin 1%
31000 cc per 1 lb of dog's weight

Jeffers sells 50 mL for $37.99 + $6 S&H for 4-10 business days. One cubic centimeter is equal to one mililiter, and converting milligrams to millilitre is a huge pain in the butt because one measures volume and another measures mass/weight and I have no idea what the density is of Ivomec to be able to calculate this quickly. So two 30 lbs dogs get 0.3 cc each, which is about 80 months of parasite prevention. $40 for nearly seven years of not worrying about tapeworms again isn't a bad deal. When kept refrigerated, it lasts at least 3 years. The vet, of course, wants us to do K9 Advantix Multi, which is $124.99 for a six month supply (from 1-800-PetMeds). $40/month for our two dogs with Advantix vs. $0.45/month with Ivomec. Hrm. Such a tough choice.

None of our mutts have collie in them, so I guess I'll be squirting nasty goo in their mouth every month, promptly followed by a treat for that awful taste. Except for our first dog. She needs to be taken in for a heartworm screening before we start doctoring her. Never, ever administer heartworm killing drugs to a dog with heartworms if you're not a passable doggy chemist. They have a tendency to keel over with their little toes in the air, if ya know what I mean. Or so I've heard. You're not supposed to treat ingrown toenails or boils at home either. I've also heard that ivermectin only kills larvae and not the adult heartworms, and that during the expected course of evolution the vile buggers are becoming immune to ivermectin, so I dunno.

And now, a series of quotes from various websites that I found helpful, followed by the general resource links at the bottom.

Ivermectin is derived from the avermectins, a family of potent, broad-spectrum antiparasitic agents isolated from fermentation of Streptomyces avermitilis.


"For both worms and ticks, I get ivermectin (Ivomec&tm; is just one brand name)—it's labeled "for cattle and swine"—at feed stores in 50-ml bottles of 1% injectable ivermectin (it's the active ingredient in Heartgard&tm;). It takes care of various worms in the canine. One bottle will possibly last most of a little dog's life, but even with large breeds, you won't be spending the small fortune that others do. I store mine in the refrigerator, even though there doesn't appear to be a shelf-life problem at room temperature. It's up to you (and maybe your vet, if you wish) what you choose, but I have had good results for several decades with this protocol."

"Personally, I don't recommend you give any kind of medications to a pregnant bitch unless the life of the bitch is in grave danger; however, I will give medications to lactating bitches. The difference is the pups are already born and not in their developing and forming stages in the womb."

"The cost is very minimal for each dog. If the 50cc bottle of Ivomec costs you $40.00, this is 80 cents per cc. Given 12 months in a row, a 20 lb. dog will take 2½cc per year. That is a cost of $2.00 for a one year prevention. The shelf life for the Ivomec is about 3 years if kept refrigerated. Therefore, this method is feasible to use even if you only have one Beagle (dog), and it is by far the cheapest and most effective prevention against heartworms. If you have two or more dogs this can save you hundreds of dollars per year."
