Our family raises old farm collies, English Shepherds. Like all the collie breeds, many within the breeds can carry the MDR1 mutation, which can cause many worming drugs (the Ivermectin/Heartguard family of drugs) to cross the blood/brain barrier and cause neurological issues in the dog. (For more on the MDR1 mutation, see the end of the article)
We try our best to “regard the life of our beasts” like it says in Proverbs 12:10.
A righteous man regardeth the life of his beast: but the tender mercies of the wicked are cruel.
We try to attend to their vitamin and mineral levels, and not poison them with chemicals and drugs, ‘naturally rearing’ our animals, dogs (and puppies) included.
When we lived in the more northern climate, the only worms we had to contend with were tapeworms.
After moving Southwest, we had both hookworm and giardia show up in stool samples for our summer litters. So we knew for our next litters, we would have to do something different.
After research, we tried the following protocol. It means weighing puppies and dosing accordingly, but, when our spring puppies’ stools were tested, they were worm free!
This is a ‘week-on’, ‘week off’ protocol; check for dead worms in the puppies stools in the ‘week off’.
Once per day:
Week 3- Black Walnut Tincture, in a dropper (be sure to ‘drop’ it in, not squirt, so that it does not enter the lungs forcefully)- ½ teaspoon per 3 wk old pup (for older dogs, 20 drops per 5lb)
Week 5- Apple Cider Vinegar (ACV) & Diatomaceous Earth (DE)1/2 tsp. each per 5lbs. Mixed with hydrated/wettened kibble. (The same dosage applies to older dogs)
Week 7- Ground Pumpkin Seeds mixed with hydrated/wettened kibble1 tsp per 10 lbs (The same dosage applies to older dogs)
Breeding Farm collies, we have heard and met people who lost their dogs to the Ivermectin deworming group of drugs, due to the MDR1 mutation.
You can purchase a cheek swab and test your dog for the mutation yourself.
