Assuming you're referring to ivermectin or it's brand name, Ivomec


Heartgaurd, a popular heartworm preventative, is ivermectin.

It's not the same as the pure form. And a helluva lot cheaper.

Do you think heartguard is the same stuff they give cattle?

No I don't think cattle are given heartgard chewable tables.

I think the active ingredient in Heartgard is ivermectin. Ivermectin also comes in other oral, topical, and injectable forms and these are often used in production animals.

Well idk about all that.

The problem with heartguard is the dosage is too low. There are some dogs that can't handle the higher dosage. I find that my BMC cur and mutts don't seem to mind.

Yeah it's not pure 100% Ivermectin.

There is a cattle wormer paste that is good, but I use the injectable type but give it oral.

Now this could be a more reasonable argument. If heartworms in the deep south are developing resistance to ivermectin at the doses typically used in heartworm preventatives it is possible that a higher dose would be required for prevention.

ivomec isn't 100% ivermectin either. Which is a good thing b/c that would make it unstable and difficult to dose at a high concentration. It's a 1% solution (or 10mg/mL) that also contains other ingredients for stability and to make it safe for injection or oral administration.

Oral forms of ivermectin like pastes and chewable tablets also combine ivermectin with other ingredients for the same reasons.

Recent information has come to light that Heartgard may be only 95% effective, rather than 100% effective, in preventing heartworm infections. That means it will destroy 95% of heartworm larvae, not that 95% of dogs receiving Heartgard will remain heartworm-free.

The dosage of ivermectin used in Heartgard was the lowest found to be 100% effective at killing heartworm larvae when the product was originally approved. Since lower doses were less effective, it's possible that higher doses may continue to be 100% effective.

Higher doses of ivermectin are safe for all dogs except those with the MDR1 mutation. Dosages as high as 50 times the amount used to prevent heartworms are used to treat mites on dogs (demodectic mange). Very high dosages may also be problematic for dogs infected with Heartworms, and those being treated with Comfortis. See Ivermectin Sensitivity above for more information.

It may be best to double the amount of ivermectin you give your dogs in order to potentially provide better protection from heartworm infection. Again, this does not apply to dogs with the MDR1 mutation.

Interesting but appears to be an opinion piece. Who wrote this? Link?

So I just got a new puppy. She went for her second round of shots today. Doc gave me the trifexis sample for her first dose. I fricked it up and have to go get another pill tomorrow. Should I ask about this other stuff y'all are talking about?

Picture for y'all. This was a month ago. She's twice that size now.

The stuff they're talking about is available online and at tractor supply I believe. It's for cattle but you give a more dilute dose to pups.

Most lilely, your vet will tell you it's extremely reckless and would never advise it.

Your vet also makes $1000s of dollars a month on pet meds.

Take that for what it's worth. Read about it online, there is lots of info on it there.

i was also given the slow kill option but was advised against it due to high resistance rates.

that's bullshite. its cheaper, that's why you were advised against it.
we had 3 rescue dogs all do the slow kill, it worked for every one of them. one of them being a 7 year old dog who was always outside and never on heartworm prevention

My Lab currently has heart worms, we've treated him once before and we had to lock him up for 4 weeks. This is an outside dog and it was terrible. I'm not sure what we will do this time b/c I don't want to crate him for another 4 weeks and he his 12 years old and money is really tight right now.

Fish- The treatment is 30 days on antibiotics then wait 30 days for them to fully work. Then a shot and crated for 4 weeks. Then 2 shots and an overnight stay at vet and then another 4 weeks in crate. Any excitement can cause heartworms parts to flush through and form blood clots so you have to keep them very calm, cool and rested until worms fully disolve. Don't know how that's possible with such a young and active dog.


You need to see another Vet. My daughter is one and has treated many dogs.

Yes, it depends how bad the worms are and what stages. The one dog that I had treated was in the late stages. BUT, he was very strong besides the worms. Was able to run along side me on my 4wheeler at 20 mph over 3 miles without any problems.

Results in more long term damage to the heart and may be leading to increased ivermectin resistance.

From the American heartworm society (veterinary specialists that focus on heartworm prevention and treatment of the disease):

quote:

Long-term Macrocyclic Lactone Administration. Slow-kill methods using continuous monthly administration of prophylactic doses of any ML are NOT RECOMMENDED.



(FYI ivermectin is a macrocyclic lactone)

I think I'll go with what the experts say over anecdotal internet message board reports...

My vet told me 1/10th CC/lb once a month and it's been 100% effective. Never had a dog get worms since.

The first time you give it to a litter of puppies, their shite looks like spaghetti. It smokes worms. That's why I think it would kill a dog that was ate up with worms.
