This Ivermectic is great because it is inexpensive and can be used to treat worms and be used as a heartworm preventative. Great for the shelter.

Pros: many uses

Cons: tastes bad

My pot bellied pigs will eat this (as recommended by the vet) So it is easier than an injection same with the horse

Pros: Does not have to be an injection

Cons: can be messy

This product works well for several treatments, mange, parasites etc.

Pros: Love this

Cons: side effects

I foster a large number of dogs and buy this product in 500 ml bottles. It is the active ingredient in Heartgard, minus the flavoring and chewy stuff, and at a tiny fraction of Heartgard's cost. It is totally effective as a heartworm preventive (administered once monthly by mouth) and is also used to treat sarcoptic and demodectic mange. Also kills hook and roundworms. I recommend it to my adopters who have multiple dogs.

This can also be used for feline heartworm preventive but must be diluted 9:1 with propylene glycol.

I wouldn't be without it!!

Pros: low cost heartworm prevention

Cons: some dogs don't like the taste

This cleared Antonio's condition in three weeks along with medicated shampoo. I thought that malnutrition from a year in a shelter environment caused some of his hair to fall out, but after a scraping... it was mange.

His coat is beautiful now and there were no adverse effects after the injection ie. lethargy, loss of appetite, or change in bowel.

Pros: worked as advertised

Cons: injection hurts like hell and dog yelps
