Ivermectin should NOT be used on dogs younger than six weeks old
Around six months, but you should never try to breed from a dog at this young age.
Ask the vet.
This will depend upon the formulation of the ivermectin - there is a mg/ml concentration on the bottle and a mg/kg body weight doseage range for canines. I would suggest talking to your veterinarian to figure out how much your dog specifically should be given for the safety of your dog. However, if you have a collie-type dog, you should not use ivermectin on it - these breeds can carry a genetic mutation that makes them exquisitely sensitive to the effects of ivermectin and you can easily overdose them even when using the lowest label dose.

While you can purchase ivermectin over the counter in pet supply stores, it is recommended that you take your dog to a veterinarian before using any medications. Ivermectin in particular can cause severe neurologic damage and death to certain collie-type dogs. Also, a veterinarian will be able to tell if the skin damage is caused by mange (skin parasites) or by some other cause (bacterial or fungal infection, allergies, etc.) that would not be resolved by ivermectin.
.1 Years Old.
Roundworms are susceptible to most commercially available dewormers, including pyrantel pamoate and ivermectin. Depending upon the dewormer, the medication is either ingested by the dog or is injected underneath the skin where it is absorbed.
