Yes you can use Ivomec.
You will probably need to buy from a Vet in Canada.
You can buy here in the US . http://www.tractorsupply.com/ivomec-reg-ivermectin-1-injection-for-cattle-swine-50-ml-2207551
what I do for HW prevention.............
You should check with your vet first to make sure your dogs test heart worm neg.
Below is what I use and do for my 10 hounds + one dog for a friend in need (dogs 8 weeks and older) , you can use your own judgment whether this will benefit you.
Ivomec 1% injection or generic Ivermectin 1% injection type are the same drug, just compare labels.
Do not use "Ivomec Plus" or any generic "Ivermectin Plus" as it contains chemicals that may harm your dog .
If you consider Heartgard the gold standard for HW prevention please read on for small, med and large dog application.
Dosing for dog 1 to 25 pounds. 68 mcg.
Dosing for dog 26 to 50. 136 mcg.
Dosing for dog 51 to 100 pounds. 272 mcg.
As you can see there is a wide safety range for this drug as dogs at the lower end of a weight range receive much more Ivermectin than dogs at the top end. Having said this notice that FDA approved HW prevention dosing is in micrograms(mcg). Heartgard uses 2.72mcg. per pound as their upper control point , so , small dogs sometimes get significantly more Ivermectin than 2.72mcg. per pound in a given weight range.
Ivermectin 1% injection straight out of the bottle has 10 mg of Ivermectin per ml/cc.
One ml/cc of Ivermectin 1% injection contains 10 mg. / 10,000 mcg. Ivermectin.
One tenth (1/10) ml/cc Ivermectin 1% contains 1mg. /1,000mcg. Ivermectin.
It is hard to measure less than 1/10 ml/cc. , so , for the small dog of say 20 pounds or less using the Heartgard dose of 68 mcg. Ivermectin , it would make sense to dilute the Ivermectin 1% injection.
Use food grade propylene glycol from local pharmacy or farm supply to dilute Ivermectin 1%.
** Do Not Use Ethylene Glycol ( antifreeze ) as this is POISON and will KILL The Dog **
I buy IVOMEC® (IVERMECTIN) 1% INJECTION FOR CATTLE & SWINE, 50 ML bottle as this is the most cost effective for me.
Go to local pharmacy and pick up a new 120 ml plastic bottle, they will prolly give it to you.
Fill with food grade propylene glycol to 99 ml/cc eyeball just under the 100 ml/cc mark. Draw up 1 ml/cc Ivermectin 1% injection ( make sure it is a full ml with no air bubble) and add to the 99 ml/cc of propylene glycol in the bottle. Shake to mix.
Always clean rubber top on Ivermectin w/alcohol, let dry and use throw away syringes graduated in ml/cc . Never stick your source bottle of Ivermectin twice with same syringe , always use a new syringe.
You have 1 ml/cc Ivermectin 1% ( 10 mg ivermectin ) now in 99 ml/cc of proplene glycol for a total of 100 ml/cc.
10mg Ivermectin divided by total solution of 100ml = 0.1 mg or 100 mcg ivermectin per ml/cc.
To dose the small dog using the Heartgard schedule of 68 mcg. just draw up .7 ml/cc or 7/10 ml/cc of diluted Ivermectin 1% and you have 70 mcg. (micrograms) of Ivermectin.
To dose the large dog with above schedule 51 to 100 pounds just draw up 2.8 ml/cc or 2 and 8/10 ml/cc and you have 280 mcg. (micrograms) of Ivermectin.
Helpful Note: When measuring my dose, I pour a little of my mixed Ivermectin solution into a small dosing cup and use a dropper graduated in ml/cc or a dosing syringe(no needle) graduated in ml/cc to draw up the dose and give to dog or put on food. Make sure if on food that dog eats everything so you know the dose was given in full. If you are ever not sure your dog ate everything just re-dose with full amount the next day. Do not pour what is left over back into source bottle or you risk contamination. Just throw any solution leftover away as it is very inexpensive.
**Always use a fresh disposable sryinge to draw Ivermectin 1% and wipe top of bottle alcohol**
********Keep everything very clean so as not to contaminate mixed solution*********
Safety Note: As with any drug , make sure that Ivermectin can be used with any other medication , supplement or spot on topical such as Flea Prevention you are using. I do know that Ivermectin should not be used with the " Comfortis Flea control medication". If in doubt as to drug interaction with any med the dog is on ckeck with your vet first before using Ivermectin.
To the above HW prevention I add generic pyrantel pamoate dosed by weight for parasite prevention.
