Hello,
I was told by a Jack Russell Terrier breeder that it would be ok to give my Jack Russel Terrier Liqui-Care P. for worms. I know this stuff is for horses. Is this ok or not? Thank you!

Dear CO,
If you’re a fan of my Ask the Vet blog, then you know I’M not a fan of giving dogs products made for horses and vice versa. So the short answer to your question is: no, giving your Jack Russell a horse dewormer is NOT okay.
The long answer is that horse dewormers are way more concentrated than dog dewormers. The product you specifically mentioned, Liqui-Care P, is designed to be given at a rate of 6ml per every 100lbs body weight. For a 1,000 pound horse, that’s 60mls, easily doable with a large syringe. But for a 10lb Jack Russell, that’s only 0.6ml, a small amount to have to be sure to measure correctly. And since this particular dewormer is a suspension—meaning it has to be shaken or stirred first because it has a tendency to separate—you have to be that much more careful when it comes to measuring.
My advice is to stick with a product specifically made for dogs and puppies. Most of the canine dewormers that contain the same active ingredient—pyrantel pamoate—are designed to be given at a rate of 5ml (one full teaspoon) per every 10lbs of body weight, a convenient amount to give to a small dog.
One other thing to think about: since pyrantel pamoate controls the roundworms Toxocara and Toxascaris and as well as the hookworms Ancylostoma and Uncinaria, why not use a heartworm preventative like HeartGard Plus which not only controls these parasites but also heartworm, a much more deadly threat?

need we mention Ivermectin poisioning in herding dogs? our Australian shepard almost died from thios. thanks
I have to say that it is good to have someone say something about this. I worked somewhere that it was popular to sell paste horse wormers to be used for dogs. This just really worried me and while the drugs are the same it just seems way to easy to accidentally overdose such a drastically smaller animal! Thanks for addressing this issue!!!
A friend of mine lost her very much loved collie from it and found it is very deadly to certain dog breeds. I would NEVER even think of giving our dogs any horse products. Different kind of animals and so much smaller in size.
You can actually test you dogs to see if they have the MDR-1 mutation which is the problem with some herding dogs and ivermectin (and other p-glycosubstrate drugs, like the antibiotic erythromycin for example). I’ve had an Australian shepherd and a rough collie both tested, both turning out to be heterozygous for the gene, and they have no trouble taking normal doses of ivermectin like the dosage in canine heartworm drugs. The collie did have a reaction the first time she was treated with erythromycin, however. Simple solution to the ivermectin/herding dog question- just have your dog tested!
I’ve used horse dewormer on my dogs on several occasions without any issues. I would not recommend it for anyone that hasn’t had training in drugs, dosages and side effects. There can be serious repercussions if you miscalculate the dosage.
I’m a breeder for Chesapeake Bay Retrievers I use Strongid on my puppies, works great and never had an issue. Oh works great on my horses too.
What do you think a proper dosage would be for a 90 lb dog
The vet asks, “Why don’t you use something intended for dogs – such as Heartguard?” I am guessing the answer to that is pretty obvious… it comes down to dollars. I wouldn’t have stumbled across this question here, if I wasn’t asking the same question – is it safe? Can I do it? Can I save myself a lot of money? You can buy horse wormer over the counter – Heartguard, need to go to a vet or get a script from a vet to buy online. So, if you do the math, I think you can imagine why the question was posed in the first place. I have a better question – if we know many formulations of wormer are safe for dogs (we’ve been giving them to dogs for years), why do vets have to prescribe them and why can’t they open up the marketplace to make the prices more competitive and affordable. If I can worm my 1000 lb palamino quarter horse for $7-12 with over the counter wormer – why can’t I do the same for my 2 Goldens and my Bernese Mountain Dog. Very frustrating!
Because there are so many more dog owners than horse owners–the opportunity to make money off a larger market–that’s my opinion.
what about using a horse dewormer for a Mastiff that is 140 ponds. I find it to be more cost effective and ok to measure for this size dog
Horse dewormer paste is formulated for a horse whose intestines are 100 ft in length it takes 2 days for paste to pass through, dogs have very short in length intestines it travels too fast to work properly they basically poop most of it out before it can kill any worms. if your vet tells you its ok to use a horse wormer i would be getting another vet! The companies that make these wormers will be the first to tell you NO!
I think safeguard was used not only for horses but people found out that by increasing the dosage because of the shortness of the dogs digestive system, Saeguard could be used for dogs. Not all dogs, but most. By specifying DOGS safeguard could increase profits. It is all about money, not the wellbeing of the dog. I have used horse wormer on puppies for many years and saved a lot of puppies lives and didnt need to have a vet tell me if they had worms or not, or what kind. It doesnt matter, and so what if some impoverished vet didnt get the fee to tell me what kind of worms they were.
I just gave my pregnant dog horse dewormer I gave her a little bit I put it on the tip of my finger I want to know will the puppies be safe I don’t want them to die
Thank you for your question. We recommend contacting your dog’s veterinarian. With such precious cargo on board, pregnant animals really do need to be “handled with care” and your vet will be the best resource to determine the ideal course of action, as well as to set up a parasite control program for your dog going forward.

I used to raise rotty’s. I gave them horse worker all the time. I was told by another breeder the only breed that can not take it is the collie breed. Or a dog that is part collie.
Hi Pam, You are absolutely correct that you need to be extra careful when providing dewormers to herding breeds like collies, as they can be particularly sensitive to certain active ingredients. That being said, we advise against providing dewormers designed for horses to any breed of dog. Since these dewormers are much more concentrated, have a tendency to separate, and do not specifically target parasites that are particularly deadly in dogs, the best suggestion we can give is to work closely with your small animal veterinarian to design a deworming program specifically for your dog.

I gave our Blue Heeler horse wormer and now it seems he is blind or seeing double. Is there a treatment for this?
Hi mjones,
We’re sorry to hear about what is going on with your dog. We recommend contacting your veterinarian to determine the best course of action.

Ours is doing the same thing did u find out anything.
Our dogs got a hold of our Safegaurd Equipellets and it appears as though 1/3 of the bag is now gone. We can’t be certain how much each may or may not have eaten vs how much the mini horse may gotten. We live quite a ways out and I’m out of work with a significant back injury so an emergency vet visit isn’t financially feasible. What do I need to look for/be concerned about?
Hi
No one that does not have experience ( many years ) with horses and dogs should stick with a vet
Now why would anyone experiment on a pregnant dog to use horse wormer ?? That’s plain Stupid
Now for years now horse wormerz Do work on dogs Not All Breeds of Dogs Some horse worners can’t be given to Bramha bulls either.
Internet is for LEARNING SO when in doubt Don’t do it Find information and dig for the best information on wormers
Now that said ..yes it can be given to dogs Only certain breeds should be avoided and if your not good in math Don’t try it
You have to know what each drug dose will do to your dog
So beware learn what a ml to cc are and don’t over dose your dogs
Avoid small dogs
My dogs are sllways getting rabbits I have No Flea problems in my home or outside / bedding
Its just the dang rabbits
So they are always getting type worms Yes I use horse wormer
Be cause mist small vets are money hungry greedy people
Most large animal vets ( not show horse vets ) make up their own wormers at a good price
I have been around and worked 40 years with dogs.horses.vets
Its safe to give dogs horse wormers but first learn what kind the amount and what breed your dog is And do get educated on it its Free to learn but a mistake can cause heart ache and that comes at a price
Ingorance can be stopped ..
I am not a vet so seek one before you do anything
Get educated on your animals word if mouth thru ignorant people will cost you a ani.also life ..Don’t experiment Get educated
I gave my dog horse wormer,do I need to be afraid.i need to know please
I need to know
