General dosing guidelines follow. For dogs: Dose is 0.0015 to 0.003 mg per pound (0.003 to 0.006 mg/kg) once a month for heartworm prevention; 0.15 mg per pound (0.3 mg/kg) once, then repeat in 14 days for skin parasites; and 0.1 mg per pound (0.2 mg/kg) once for gastrointestinal parasites.
Given at the proper doses and under the supervision of a veterinarian, ivermectin is safe for most dogs and is very effective in treating and preventing a number of parasites. However, a dog with the mutation who ingests the drug can have a severe, life-threatening reaction called ivermectin toxicity.
Ivermectin is approved for use in dogs and cats for the prevention of dirofilariasis at oral doses of 0.006 and 0.024 mg/kg, respectively, once a month. Most dogs tolerate oral ivermectin dosages up to 2.5 mg/kg before clinical signs of toxicity occur.
– For most dogs signs of toxicosis may be seen at doses greater than 2 mg/kg (0.9 mg/lb). Dogs affected by genetic sensitivity can have toxicosis with as little as 0.1 mg/kg (0.04 mg/lb). – Clinical signs of toxicosis in cats have been reported at doses of 0.3-0.4 mg/kg (0.1 mg/lb).
Ivermectin is given monthly for heartworm prevention, daily or every other day for demodectic mange treatment, and every week or couple of weeks for most mites. If a dose of heartworm preventive is accidentally forgotten, it is important to give it as soon as it is remembered.
A: “Slow kill,” meaning the administration of ivermectin products alone to kill adult heartworms is not recommended. It will take many months to a few years before adult heartworms are killed; all the while they continue to damage the heart and lungs of the infected dog.

Ivermectin is approved for use in dogs at oral doses up to 0.024 milligrams per kilogram, whereas most dogs can tolerate doses of up to 2.5 milligrams per kilogram without issue.
Clinical signs of poisoning include dilated pupils, difficulty walking (ataxia), tremors, drooling, seizures, coma, inability to breath, and death. Without aggressive treatment, ivermectin poisoning can be deadly.
Maximum Dosage

A genetic sensitivity to ivermectin can be seen in several breeds, but is more commonly seen in the following breeds: Collie. Old English sheepdog. Shetland sheepdog (Sheltie)
In those dogs, ivermectin can cause a fatal side effect characterized by symptoms of shock including vomiting, hypothermia and depression. Ivermectin has also been associated with a central nervous system event in some dogs which leads to loss of coordination, seizures, and in some cases, death.
The severity of clinical signs associated with ivermectin intoxication depends upon the level of exposure and age of animals and includes lethargy, bradycardia, ataxia, hypersalivation, vomiting, muscular tremors, mydriasis, coma, obtundation, respiratory failure, apparent blindness and even death [2, 3, 14, 15].
Heartworm preventives do not kill adult heartworms. Also, giving a heartworm preventive to a dog infected with adult heartworms may be harmful or deadly.
Dog life expectancy after heartworm treatment depends on how much damage was done, how the dog tolerates treatment, and the overall health of the dog. In general, dogs that are asymptomatic for heartworm disease can live a long, healthy life free of symptoms after treatment.
Ivermectin dosage for dogs
The general rule of thumb for ivermectin dosage is 0.0015 – 0.003 mg per pound each month for heartworm prevention. For external parasite treatment, you typically administer 0.15 mg per pound for two weeks and, for internal parasites, 0.1 mg per pound one time.

Ivermectin is used to treat various parasitic infestations of intestine, skin and hair infestation including scabies and pediculosis and certain inflammatory diseases.
Horse Ivermectin Is Too Strong for Dogs
Ivermectin paste is formulated for horses and should not be given to dogs. Each milligram of paste contains 18.7 mg of ivermectin. A small 6-gram tube of medication that strength contains enough ivermectin to treat a horse.
Description: Corectin tablets contains ivermectin which is an ecto-endoparasiticide in nature. It is also effective against both external and internal parasites. Avoid dose dumping side effect with advantage of 6 mg melt in mouth dissolving tablets.
As an anthelmintic (“Dewormer”) medication it can be used to treat multiple species of internal and external parasites.

Ivermectin. Ivermectin-based Heartworm medications are given orally once per month. Ivermectin is a broad-spectrum antiparasitic drug used in humans and animals. In monthly Heartworm prevention, the dose of ivermectin is low but effective at killing Heartworm larvae.
Of course, these dogs can be given heartworm preventatives that do not utilize ivermectin (Revolution [selamectin] and Advantage multi [moxidectin] are both topical, so they treat fleas as well as prevent heartworm disease). Both of these medications are fairly new and will need to be purchased from your veterinarian.
Some of the products that may interact with this drug include: barbiturates (such as phenobarbital, butalbital), benzodiazepines (such as clonazepam, lorazepam), sodium oxybate (GHB), valproic acid.
