Because this has black walnut, I first tested this out on my dogs at 1/4 of a dose with gradually increasing doses up to the recommended dosage for their weight (I had to look this up online since I have a dog that weighs 130lbs) to make sure it didn’t upset their tummy’s too much or to see if they have allergies to any of the ingredients. They did well and we had no issues. In fact they like it because it is duck flavored. I like that it has pumpkin seed since that provides a natural double whammy for parasites. I especially like the 2 billion CFU of probiotics they include in the mix. You aren’t just eliminating potential parasites but you are also supporting gut health and crowding out anything in their gut that doesn’t belong. I will order this again since you get 60 total servings in 2 fluid ounces. This is enough to do the 21 day cleans for both of my pups. As a tip, it’s helpful to put the last day on the calendar so you don’t forget how many days you have given it.

As a side note, it is not tested on pregnant or lactating dogs so you will want to check with your vet before giving your dog this product.
