Ivermectrin dewormer kills dogs and horses

Ivermectrin, a dewormer for animals, is extremely dangerous and deadly to certain dogs and horses. I believe it is also sold under the name of Zymectrin.

Never give Ivermectrin to any working dog, especially collies. My friend's dog, an Australian Shepherd, licked up some ivermectrin that had fallen to the ground. It cost $12,000.00 and weeks of intensive care at the vet and then more care at home to make her well. She couldn't see, she would put her mouth in the water bowl and stay there if she wasn't watched. Her head bobbed and she was totally out of. It was awful, but they saved her.

Never give Ivermectrin to an Arabian horse. I lost my boy Icon the night after I dewormed him. The Ivermectrin caused him to colic. The next morning he had surgery, but some of his organs were already necrotic. We could have tried to save him, but it would have been a difficult recovery at best- more colic, maybe foundering, pain from the surgical wounds, and still, possible death.

Once I learned he would suffer to live, I requested that they not wake him up from surgery. It was beyond awful and I will never forget the pain he suffered. It didn't have to happen.

Never give Ivermectrin to any kind of collie or working dog. It was also lethal to Icon, an Arabian horse. Other horse breeds can also be affected. I read that Thoroughbreds sometimes can't tolerate Ivermectrine either. I don't know what other breeds might be affected.

I never knew this before Icon died. I wish I had known. Now you know and can pass the information along to collie owners, working dog owners, and horse owners.

I wish I had known.

(Icon was an incredibly beautiful and good horse. We shared the same birthday, his gray dapples slowly turning white through our years together. He was a beautiful creature, a Polish Arabian in the prime of his life, given to me years ago by my father, who is also gone now. I miss them both so much).

Even some vets are not aware of the dangers of Ivermectrin. There is some kind of genetic testing that can identify the animals who can't have Ivermectrin... I just don't use it at all now.

Pass this information along to other dog and horse owners in case they don't know either.
