My Husband and I have breed dogs for close to 20 years, and this is the first time using this Medication on our 4 month old Mini Dachshunds. He gave them the dose that seemed to be correct. The Next day, One was near death and the other two were very sick as well. This medication, should not be used on dogs. One of mine died last night, and one seems to be blind. It is not worth the effect this could have on your dog and you as the owner. We of course have decide against using this medication on any of our pets. My husband spoke to a feed store owner today, and He too agrees. He also stated that many people purchase this to give to their Beagles. Please use Zimecterin Gold only on horses. This medication is no joke and causes a sad slow, death for the animals.

I have a 5 months old Pitbull/German Shepard mix. He was diagnosed with Demadex Mange and was prescribed Ivermectin. He was on a low dose at first but then they increased it. After they did that we noticed his pupils dilated and the next day after another dose he became very ill. He is in the hospital now and he’s stable, but I am worried he will have permanent damage. I also question why the vet didn’t think to test him or take precautions since he has one of the sensitive breeds in him.

My 5 month old puppy was diagnosed with demodetic mange. The vet gave him ivamec 2cc every day. The second day i noticed that his back legs began to get wobbly. Does he have ivamec posioning and if so what should i do and is there any thing else to cure demodectic mange?

Your vet can best tell you, but many dogs overcome this.

Dogs can sometimes have a reaction to ivermectin if they are heartworm positive or they can have a bad reaction to the ivermectin itself for various reasons. Right now, your vet is the best source of info on this.

Best wishes, and please let me know how she does. Prayers to you both! And think positive! Think of many long years together once you get this behind you!

I just adopted a lab/retriever mix from a local shelter 10 days ago. She has been put on ivomec teo days before we got her as a treatment for demodectic mange. She has spent the last two days in the vet hospital on IV ans steriod drip. She was falling over, deeply depressed, swollen eyes, etc. They also diagnosed her as heartworm positive, which I was told she didn’t have upon adoption. Poor baby. She’s only 2 years old. Will she ever get better? I fear not. Do dogs recover from this toxicity?

I am so sorry to hear about your boy. I hope he recovers fully. Let us know.

Our 12 yr old very healthy male golden retriever had a severe adverse reaction to Heartgard Plus three days ago. He had all the symptoms listed above (except seizure, coma, and death… so far anyway). He’s taken this stuff for years with only getting nausea in the past. He vomited within an hour but still (today) has dilated pupils, fear & paranoia, difficulty standing, and staggers like a drunken sailor. The vet only gave him some anti-nausea pills. She seemed incredulous that this was the cause. I can assure you, I watch my dogs very closely and this reaction was caused by the Heartgard. I can coax him to drink and eat boiled chicken but mostly he’s just laying around looking miserable (POOR BABY!).

So… it’s not just collies and it’s not just “high” doses that can cause problems. I just hope he recovers from this because I can’t find anything (online or from the vet) that talks about possible long term damage.

It is to notice Finnish Lapinkoiras can carry the MDR1 lethal mutation too. Recently one dog of this breed died in Canada from ivermectin.

Here’s to Rosey… and many more healthy, happy years! And to her playmates as well. Do you mix the 1% with anything to disguise the taste?

I have a poodle schnauzer cross, Rosey, that had her 18th birthday in June. She averages 18-20lbs weight. I have been giving her 2/10 ml 1% IVOMEC [injectable-but dosed orally in dogs] since I adopted her at 6 months of age. In our South Central U.S. location I give this every 30 days year round. I was a veterinary assistant at the time I acquired old Rosey. This was the dose recommended by the very good vet that I worked for. I had several dogs at the time and it was most economical for me. I have never used anything else for parasite control on any of my dogs. They have all stayed healthy and lived long lives on it. This includes many purebreds as well as my favorite mutts. [no collies of course, but I did have one Aussie that was on it with no problems]. I now have two Jack Russell Terrier / Min Pin mix pups that are 9 months old which I have started on the IVOMEC. Rosey plays with them and they are all a lively bunch. We also have an Anatolian Shepherd Dog which weighs 110 lbs. He is on the 1% IVOMEC and gets 1 full ml every month. No ill effects for him either. Of course dogs should be heartworm free before begining this high a dosage, but keep in mind that too low a dosage is not 100% effective for heartworm prevention and does nothing for intestinal worms either. The dose in Heartguard is NOT effective on other [intestinal] parasites. Old Rosey has NEVER had any intestinal parasites and has had a clean [occult] heartworm test every year of her life as well as clean fecal exams. I attribute this, thanks to the IVOMEC, and her hearty mix-breed constitution to her longevity. I expect the old gal has several more good years in her yet!
